In a application there is an option to upload file and the file name is dynamically set with user's Name and Phone number. When user fills the phone number as +965-97324246. The file name is saved a Name_+965-97324246.pdf. Since "+" is there the hyper link ofthe file gave error when we try to view in browser. Thus we can use Regex to ignore special charaters. please find the sample below:

Sample:

using System;

using System.Text.RegularExpressions;

namespace Regex_Replace

{

// Remove forbidden chars for filename

class Class1

{

static void Main(string[] args)

{

string sourceStr = @"1\2/3:4*5?6""7<8+>90";

string rgPattern = @"[\\\/:\*\?""<>+]";

Regex oRegex = new Regex(rgPattern);

Console.WriteLine(oRegex.Replace(sourceStr, ""));

Console.Write("\nPress [Enter] to Exit ... ");

Console.ReadLine();

}

}

}

Hope it Helps...

Happy Diwali :)
