You can also use regular expressions

e.g. for email you can use ^[\w-]+@[\w-]+\.(com|net|org|edu|mil)$

I mean if we type any numbers or any special symbols,it should display errror that"U should enter only characters.
And in Pincode,phone number we should enter only numbers.other than numbers ,it should display error.
   For Website and for E-mailID,it should contain @ at the right side only n only onedot(.), after dot we have either com or org.

      Am doing this in .net using Project type as VisualC# in asp.net web application.
    Now am learning C#,but I want the code in c# with all controls should be applied including validations. Plz send as soon as possible.Its urgent.

For the numbers, you can do something like this :
char[] numbers = {'1', '2', '3', '4', '5', '6', '7', '8', '9', '0'};
if (textBox1.Text.IndexOfAny(numbers) != -1)
MessageBox.Show("found numbers");
else
MessageBox.Show("didn't found number");

and for the email, you can do such validation as

if (textBox1.Text.IndexOf('@') != -1 && textBox1.Text.IndexOf('.') != -1 && textBox1.Text.IndexOf('@') < textBox1.Text.IndexOf('.'))

You will need to add some validation to make sure that "@." doesn't validate successfully...have a deeper look at the IndexOf method and other string manipulation methods.
