How to use the varchar data type in c#?

NO this is untrue, When you step through a process by changing the debugging settings located in VS you can step through a SQL script process also if you run an example like this where a table has varchar values set into it.

Try
{
  using (SqlCommand cmd = new SqlCommand(examplestring, connection))
  {
    cmd.ExecutenonQuery();
  }
 }
 catch
 {
    return;
  }

now put a breakpoint onto the catch statement and in the examplestring have a string called '456789 - 1' equal to Itemnumber varchar(25) in the SQL table.

The catch will get the following error SqlException was caught - Error converting data type varchar to numeric.

Now query string is set as a string cause that is the only way the SqlCommand works look it up on MSDN : System.Data.SqlClient.SqlCommand

So yes Lasse there is varchar in .NET.
