  The following code is confusing. There is a function, which only returns the given parameter. When I call the Function with a Directory it works. But when I call the function with a SqlDataReader it doesn't.
  
  

  I use power shell 1.0.
  
  

  Can anybody tell me what is wrong?
  
  

  function test ($p) {
  
   return $p;
  
  }
  
  
  
  $x = (Get-ChildItem)[0];
  
  $x = test -p $x;
  
  
  
  if ($x -eq $null) {
  
   echo "this will not be shown";
  
  }
  
  
  
  $conn = New-Object System.Data.SqlClient.SqlConnection("Server=***;Database=***;Password=***;User ID=***;MultipleActiveResultSets=True;Workstation ID=sync_reader");
  
  $conn.Open();
  
  
  
  $cmd = New-Object System.Data.SqlClient.SqlCommand;
  
  $cmd.Connection = $conn;
  
  $cmd.CommandText = "SELECT * FROM dbo.TABLE_COLUMNS";
  
  $x = $cmd.ExecuteReader();
  
  
  
  if ($x -eq $null) {
  
   echo "this will not be shown";
  
  }
  
  
  
  $x = test -p $x;
  
  
  
  if ($x -eq $null) {
  
   echo "this will be shown";
  
  }
  
  
  
  $conn.Close();
