I have a small application in VB.NET that works and now I am converting it to C#.

I am trying to create an Update Function using C#. The Form makes a call to my Data Class.

In the Form’s Update Function:

private string UserID;
private string FirstName;

UserID = txtUserID.Text;
FirstName = txtFirstName.Text;

ScrapDB.UpdateUser(UserID, FirstName); // I am not sure of this part!  It throws these errors: 

Errors:
1. c:\inetpub\wwwroot\eScrap_C\Users.aspx.cs(85): Argument '1': cannot convert from 'string' to 'eScrap_C.ScrapDB.User'

2. c:\inetpub\wwwroot\eScrap_C\Users.aspx.cs(85): Argument '2': cannot convert from 'string' to 'eScrap_C.ScrapDB.User'


ScrapDB.cs

public class User
		{
			public string UserID;
			public string FirstName;
			public string LastName;
			public string PhoneExt;
			public string DepartmentCode;
			public string PositionName;

		}

public void UpdateUser(User UserID,User FirstName)

SqlConnection UpdateUserConnection = GetConnection();
{
		
			string UpdateStatement	= "UPDATE UserInfo SET  "
				+ "UserID = @UserID, "
				+ "FirstName = @FirstName ";

SqlCommand UpdateCommand = new SqlCommand(UpdateStatement, UpdateUserConnection);
UpdateCommand.Parameters.Add("@UserID", UserID);
UpdateCommand.Parameters.Add("@FirstName", FirstName);
		
UpdateUserConnection.Open();

UpdateCommand.ExecuteNonQuery();
UpdateUserConnection.Close();
}

Any suggestion are most welcomed!
