Return Value

Type: System.Int32
The hash code for the current instance.

The following example demonstrates how to use the GetHashCode method to return a hash code for an instance of UTF8Encoding. Notice that the hash code returned by this method varies depending on the constructor used to create the UTF8Encoding.

using System;
using System.Text;

class UTF8EncodingExample {
    public static void Main() {
        // Many ways to instantiate a UTF8 encoding.
        UTF8Encoding UTF8a = new UTF8Encoding();
        Encoding UTF8b = Encoding.UTF8;
        Encoding UTF8c = new UTF8Encoding(true, true);
        Encoding UTF8d = new UTF8Encoding(false, false);

        // But not all are the same.
