Introduction:
Here I will explain how to use regular
expression or regex in c#
to replace all special characters with space in string using c#,
vb.net.
Description:
In previous articles I explained constructors in c#, polymorphism example in c#, delegates in c# with example, Difference b/w compile time and runtime polymorphism, sealed classes in c#.net and many articles relating to c#,
vb.net,
code snippets. Now I will explain how to replace all
special characters in string with space in c#,
vb.net.
C#
Code to replace special characters with spaces
If we want to replace all special characters in string
with spaces we need to write code like as shown below
using System;
using System.Text.RegularExpressions;
namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
string str = "welcome@to-aspdotnet#sueresh.com";
string replacestr= Regex.Replace(str,
"[^a-zA-Z0-9_]+", " ");
Console.WriteLine(replacestr);
Console.ReadLine();
}
}
}
|
VB.NET Code
Imports System.Text.RegularExpressions
Module Module1
Sub Main()
Dim str As String = "welcome@to-aspdotnet#sueresh.com"
Dim replacestr As String = Regex.Replace(str, "[^a-zA-Z0-9_]+", "
")
Console.WriteLine(replacestr)
Console.ReadLine()
End Sub
End Module
|
If we run above code we will get output like as shown
below

Its very helpful. thx.
Very helpful code.....
But there is a small mistake in C# code. Third parameter (MatchEvaluator) should be " " instead of "-".
VB.Net code is correct.
