Question

I am taking a string value from a textbox named txtLastAppointmentNo and
I want to convert it to an int and then store it in a database using Linq to sql but I am getting error “input string was not in proper format”.

My input string is 2.

My code is:

      objnew.lastAppointmentNo=Convert.ToInt32(txtLastAppointmenNo.Text);

Please point out my mistake.

Assuming you are using WebForms, then you just need to access the textbox value and not the textbox itself:

objnew.lastAppointmentNo = Convert.ToInt32(txtLastAppointmenNo.Text);

Or if you are referencing the HTML control then:

objnew.lastAppointmentNo = Convert.ToInt32(Request["txtLastAppointmenNo"]);
