Here we have discuss about the TextBox Validation,for that TextBox takes The Only indian Format Phnumber,for that here is the code for it,and also we have to using one more Namespace is using System.Text.RegularExpressions;
Code for Indian Formate Phone Number:
this code write in the txtPhnumbr_Validating Event

            Regex phNum = new Regex("^\\+[9][1][-][\\d]{10}$");

            Match getmatch = phNum.Match(textBox1.Text);

            if (getmatch.Success)
            {
                errorProvider1.SetError(this.textBox1, "");
            }
            else
            {
                errorProvider1.SetError(this.textBox1, "Phnum Should 10 Digits and Format +91-XXXXXXXXXX");
            }
