    Hi,

    I was wandering if you could help, I am attempting to create the following policy.

    I have named the policy FilteredExpiration.cs

    When I go to build it, it comes up with the following error:

    Error 1 'ExpirationTest.FilteredExpiration' does not implement interface member 'Microsoft.Office.RecordsManagement.PolicyFeatures.IExpirationFormula.ComputeExpireDate(Microsoft.SharePoint.SPListItem, System.Xml.XmlNode)' C:\Users\Alex.Nagy\Documents\Visual Studio 2010\Projects\ExpirationTest\ExpirationTest\FilteredExpiration.cs 11 18

    using System.Web;
using Microsoft.SharePoint;
using Microsoft.Office.RecordsManagement;
using Microsoft.Office.RecordsManagement.PolicyFeatures;
using Microsoft.Office.DocumentManagement;
using Microsoft.SharePoint.Utilities;
using System;

namespace ExpirationTest
{
    public class FilteredExpiration : IExpirationFormula
    {
        public DateTime? ComputeExpiteDate(SPListItem item, System.Xml.XmlNode parametersData)
        {

            //Check if item is in warning period
            //If it is, send warning email stating
            //that document will expire in a month

            DateTime expiryDate = new DateTime();
            if (item["_dlc_ExpireDate"] != null)
            {

                //Get item's expiry date.
                expiryDate = (DateTime)item["_dlc_ExpireDate"];

                //Find remaining time to expiry
                TimeSpan diff = expiryDate.Subtract(DateTime.Now);

                //If less then a month, send warning email
                if (diff.Minutes <= 2)
                    SendWarningEmail(item);

            }

            if (item["CollectMe"].ToString().Equals("True"))
                return DateTime.Now;
            else
                return ((DateTime)item["Modified"]).AddDays(365);

        }

        private void SendWarningEmail(SPListItem item)
        {
            try
            {
                SPSite thisSite = new SPSite("http://sharepoint:14236");
                SPWeb thisWeb = thisSite.RootWeb;
                string toField = "Alex.Nagy@centraxtcl.com";
                string subject = "Test Message";
                string body = "Document - " + item.Name + " - will expire in a month.";
                HttpContext oldContext = HttpContext.Current;
                HttpContext.Current = null;
                bool success = SPUtility.SendEmail(thisWeb, true, true, toField, subject, body);
                HttpContext.Current = oldContext;

            }
            catch (Exception ex)
            {
                //handle exception
            }

        }
    }
}

    any ideas ?

    Your method signature does not match the interface.

    DateTime? its different than Nullable<DateTime>

    http://msdn.microsoft.com/en-us/library/microsoft.office.recordsmanagement.policyfeatures.iexpirationformula.computeexpiredate.aspx

    Change it and let me know if it compiles, also change the typo error.ComputeExpiteDate to ComputeExpireDate

    Hi,

    Thanks for the reply. I have had a look at the link and have changed it too:

    using System.Web;
using Microsoft.SharePoint;
using Microsoft.Office.RecordsManagement;
using Microsoft.Office.RecordsManagement.PolicyFeatures;
using Microsoft.Office.DocumentManagement;
using Microsoft.SharePoint.Utilities;
using System;

namespace ExpirationTest
{
    public class FilteredExpiration : IExpirationFormula
    {
       public Nullable <DateTime> ComputeExpiteDate(SPListItem item, System.Xml.XmlNode parametersData)
        {

            //Check if item is in warning period
            //If it is, send warning email stating
            //that document will expire in a month

            DateTime expiryDate = new DateTime();
            if (item["_dlc_ExpireDate"] != null)
            {

                //Get item's expiry date.
                expiryDate = (DateTime)item["_dlc_ExpireDate"];

                //Find remaining time to expiry
                TimeSpan diff = expiryDate.Subtract(DateTime.Now);

                //If less then a month, send warning email
                if (diff.Minutes <= 2)
                    SendWarningEmail(item);

            }

            if (item["CollectMe"].ToString().Equals("True"))
                return DateTime.Now;
            else
                return ((DateTime)item["Modified"]).AddDays(365);

        }

    I still get the error:

    Error 1 'ExpirationTest.FilteredExpiration' does not implement interface member 'Microsoft.Office.RecordsManagement.PolicyFeatures.IExpirationFormula.ComputeExpireDate(Microsoft.SharePoint.SPListItem, System.Xml.XmlNode)' C:\Users\Alex.Nagy\Documents\Visual Studio 2010\Projects\ExpirationTest\ExpirationTest\FilteredExpiration.cs 11 18 ExpirationTest

    Hi

    There's a typo in your code. The interface method's name is ComputeExpireDate. You have named it ComputeExpiteDate..

    My bad.

    I have since corrected the spelling mistake in the code and I am now getting the following error.

    Error 1 The type or namespace name 'HttpContext' could not be found (are you missing a using directive or an assembly reference?) C:\Users\Alex.Nagy\Documents\Visual Studio 2010\Projects\ExpirationTest\ExpirationTest\FilteredExpiration.cs 52 17 ExpirationTest

    Error 2 The name 'HttpContext' does not exist in the current context C:\Users\Alex.Nagy\Documents\Visual Studio 2010\Projects\ExpirationTest\ExpirationTest\FilteredExpiration.cs 52 42 ExpirationTest

    you have to add a reference to System.Web

    https://www.google.com/search?ix=sea&sourceid=chrome&ie=UTF-8&q=HttpContext

    Hi, 

    I have already put using system.web at the top of the code, do I need to reference it again further down the code?

    using System.Web;
using Microsoft.SharePoint;
using Microsoft.Office.RecordsManagement;
using Microsoft.Office.RecordsManagement.PolicyFeatures;
using Microsoft.Office.DocumentManagement;
using Microsoft.SharePoint.Utilities;
using System;

namespace ExpirationTest
{
    public class FilteredExpiration : IExpirationFormula
    {
       public Nullable <DateTime> ComputeExpireDate(SPListItem item, System.Xml.XmlNode parametersData)
        {

            //Check if item is in warning period
            //If it is, send warning email stating
            //that document will expire in a month

            DateTime expiryDate = new DateTime();
            if (item["_dlc_ExpireDate"] != null)
            {

                //Get item's expiry date.
                expiryDate = (DateTime)item["_dlc_ExpireDate"];

                //Find remaining time to expiry
                TimeSpan diff = expiryDate.Subtract(DateTime.Now);

                //If less then a month, send warning email
                if (diff.Minutes <= 2)
                    SendWarningEmail(item);

            }

            if (item["CollectMe"].ToString().Equals("True"))
                return DateTime.Now;
            else
                return ((DateTime)item["Modified"]).AddDays(365);

        }

        private void SendWarningEmail(SPListItem item)
        {
            try
            {
                SPSite thisSite = new SPSite("http://sharepoint:14236");
                SPWeb thisWeb = thisSite.RootWeb;
                string toField = "Alex.Nagy@centraxtcl.com";
                string subject = "Test Message";
                string body = "Document - " + item.Name + " - will expire in a month.";
                HttpContext oldContext = HttpContext.Current;
                HttpContext.Current = null;
                bool success = SPUtility.SendEmail(thisWeb, true, true, toField, subject, body);
                HttpContext.Current = oldContext;

            }
            catch (Exception ex)
            {
                //handle exception
            }

        }
    }
}

    system.web.dll is not added to the project by default, you have to add it before you can use it in the using statement.

    References, right click, add reference, find the dll

    Just for clarification sake, actually, DateTime? is not different than Nullable<DateTime>.  Albeit different from the MSDN example you referenced, the code sample below uses DateTime?

    http://code.msdn.microsoft.com/office/SharePoint-2010-Developing-37ad2f01/sourcecode?fileId=49663&pathId=934555589

    DateTime? is shorthand for Nullable<DateTime> as with Int?, GUID? etc. etc.
