Unable to read a SQL UniqueIdentifier element in C#

Unable to read a SQL UniqueIdentifier element in C#

Unable to read a SQL UniqueIdentifier element in C#

I have a ASP.NET page in C# that calls a stored procedure and returns a small result set, and I'm unable to read the UniqueIdentifer element from that result set. What am I doing wrong?


Here is the final select statement of my Stored Procedure that contains the value I need the C# routine to work with. The 'UserId' field is defined as a uniqueidentifier in the SQL table.


SELECT PeopleId, UserId, FirstName, LastName, UserType FROM People 
	WHERE PeopleId = @UserNumber 

This is the code from the ASP 'cs' file


// Get results from stored procedure
string cSysUserCode;
string cAHFUserId;
int nAHFUserId;
string cFullName;
UserReader = command.ExecuteReader();
if (UserReader.HasRows)
   while (UserReader.Read())
      // This first value is not converting to string...
      cSysUserCode = UserReader["UserId"].ToString().Trim();
      cAHFUserId = UserReader["PeopleId"].ToString();
      nAHFUserId = Convert.ToInt16(cAHFUserId);
      cFullName = UserReader["FirstName"].ToString().Trim()
          + " " + UserReader["LastName"].ToString().Trim();

Here is the error message that I'm getting

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IndexOutOfRangeException: UserId

cSysUserCode = UserReader["UserId"].ToString().Trim();

RE: Unable to read a SQL UniqueIdentifier element in C#

Never Mind... I was able to figure it out.
