DateTime application

Question

Can anyone help me with this? I'm trying to calculate the number of days of  a start and a finish date and put the result of days in a textbox. The problem I'm having is the conversion, I'm getting 243.00:00:00 mailto:[email protected]. Also put result on forum

Here's the code: 

                

System.DateTime dtmStartDate = new System.DateTime(2007,1,1);

System.DateTime dtmFinishDate = new System.DateTime(2007,9,1);

System.TimeSpan intDays=dtmFinishDate.Subtract(dtmStartDate);

txtDays.Text=Convert.ToString( intDays );
