String.Replace Method (Char, Char)

Replaces all occurrences of a specified Unicode character in this instance with another specified Unicode character.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public string Replace (
	char oldChar,
	char newChar
)
public String Replace (
	char oldChar, 
	char newChar
)
public function Replace (
	oldChar : char, 
	newChar : char
) : String
Not applicable.

Parameters

oldChar

A Unicode character to be replaced.

newChar

A Unicode character to replace all occurrences of oldChar.

Return Value

A String equivalent to this instance but with all instances of oldChar replaced with newChar.

This method performs an ordinal (case-sensitive and culture-insensitive) search to find oldChar.

The following code example creates a comma separated value list by substituting commas for the blanks between a series of numbers.

using System;

class stringReplace1 {
    public static void Main() {
        String str = "1 2 3 4 5 6 7 8 9";
        Console.WriteLine("Original string: \"{0}\"", str);
        Console.WriteLine("CSV string:      \"{0}\"", str.Replace(' ', ','));
    }
}
//
// This example produces the following output:
// Original string: "1 2 3 4 5 6 7 8 9"
// CSV string:      "1,2,3,4,5,6,7,8,9"
//

import System.*;

class StringReplace1
{
    public static void main(String[] args)
    {
        String str = "1 2 3 4 5 6 7 8 9";
        Console.WriteLine("Original string: \"{0}\"", str);
        Console.WriteLine("CSV string:      \"{0}\"", str.Replace(' ', ','));
    } //main
} //StringReplace1
//
// This example produces the following output:
// Original string: "1 2 3 4 5 6 7 8 9"
// CSV string:      "1,2,3,4,5,6,7,8,9"
