This happens when the length of textbox2 value is less than 5000, try this:

C#

String PostData = TextBox2.Text;
if (PostData.Length > 5000){
    PostData = PostData.Substring(0,5000);
}

or it could be like this in one line :

string PostData = (TextBox2.Text.Length > 5000 ? TextBox2.Text.Substring(0, 5000) : TextBox2.Text);
