You can use regular expression for this rather using multiple if else condition. Regex class is available under namespace using System.Text.RegularExpressions; Here's the code for mobile validation: public bool IsCorrectMobileNumber( String strNumber) { Regex mobilePattern = new Regex ( @^[1-9]\d{10}$ ); return !mobilePattern.IsMatch(strNumber); }

if(txt_Mobile.Text.Length>=10 && (!txt_Mobile.StartsWith(0))) //Do next thing else //throw error message
