String.ToString Method

Returns this instance of String; no actual conversion is performed.

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

public override string ToString()

Return Value

Type: System.String
The current string.

Because this method simply returns the current string unchanged, there is no need to call it directly. It is usually called implicitly in a composite formatting operation, as the example shows.

The following example demonstrates the ToString method. Note that the example does not explicitly call the ToString method. Instead, the method is called implicitly by the composite formatting feature.

using System;

class stringToString {
    public static void Main() {
    String str1 = "123";
    String str2 = "abc";

    Console.WriteLine("Original str1: {0}", str1);
    Console.WriteLine("Original str2: {0}", str2);
    Console.WriteLine("str1 same as str2?: {0}", Object.ReferenceEquals(str1, str2));

    str2 = str1.ToString();
    Console.WriteLine();
    Console.WriteLine("New str2:      {0}", str2);
    Console.WriteLine("str1 same as str2?: {0}", Object.ReferenceEquals(str1, str2));
    }
}
/*
This code produces the following output:
Original str1: 123
Original str2: abc
str1 same as str2?: False

New str2:      123
str1 same as str2?: True
*/
