@Pawan it would be great if you post code rather than posting image. nobody can copy it for usage.

You can use below code.

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
