How to use regex to remove whitespace in C#

[AbhayD]

I am having a small piece of code that displays a line after each statement. I want to remove this unnecessary extra lines. I thought regex would be the best solution for this. But now the problem is the that I don't know how to use regex in C#? Does anyone over here know about this? Please help!

Here is how regex is used:

string str1 = your_string;
Regex regex = new Regex(@"\W");
string newString = regex.Replace(str1, " ");
Console.WriteLine (newString);

You can even try out the code as below:

public static string RemoveWhitespace (this string myStr)
{
    try
    {
        return new Regex(@"\s*").Replace(myStr, string.Empty);
    }
    catch (Exception)
    {
        return myStr;
    }
}

Well is what I did it once:

using System;
using System.Text.RegularExpressions;

class MainClass
{
    static void Main()
    {
        string s1 = "My name   is Zecho.";
        Regex r1 = new Regex(@"\s+");
        string s2 = r1.Replace(s1, @" ");
        Console.WriteLine(s2);
        Console.ReadLine();
    }
}

Output of the code would be as follows:

My name is Zecho.
