Debugging SQL Server Statements In Code

How can I view the raw SQL code that ASP.NET sends to SQL Server when using parameters?

The code below doesn't display the actual SQL statement, but instead: System.Data.SqlClient.SqlCommand.

string SQL = "INSERT INTO [BLAH] VALUES (@startDate)";
SqlConnection mySqlConn = new SqlConnection(ConfigurationSettings.AppSettings["DSN"]);
SqlCommand mySqlCmd = new SqlCommand(SQL, mySqlConn);

mySqlCmd.Parameters.Add(new SqlParameter("@startDate", SqlDbType.DateTime));
mySqlCmd.Parameters["@startDate"].Value = Request.Form["start_date"];

lblSQLDebug.Text = mySqlCmd.ToString();

TIA.
