傳回這個執行個體的雜湊碼。

public override int GetHashCode();

傳回

Int32

32 位元帶正負號的整數雜湊碼。

範例

下列範例會使用 GetHashCode 方法產生數 TimeSpan 個物件的雜湊碼。

// Example for the TimeSpan.GetHashCode( ) method.
using System;

class GetHashCode
{
    static void DisplayHashCode( TimeSpan interval )
    {
        // Create a hash code and a string representation of 
        // the TimeSpan parameter.
        string  timeInterval = interval.ToString( );
        int     hashCode = interval.GetHashCode( );

        // Pad the end of the TimeSpan string with spaces if it 
        // does not contain milliseconds.
        int pIndex = timeInterval.IndexOf( ':' );
        pIndex = timeInterval.IndexOf( '.', pIndex );
        if( pIndex < 0 )   timeInterval += "        ";

        Console.WriteLine( "{0,22}   0x{1:X8}, {1}", 
            timeInterval, hashCode );
    }

    static void Main( )
    {
        Console.WriteLine(
            "This example of TimeSpan.GetHashCode( ) generates " +
            "the following \noutput, which displays " +
            "the hash codes of representative TimeSpan \n" +
            "objects in hexadecimal and decimal formats.\n" );
        Console.WriteLine( "{0,22}   {1,10}", 
            "TimeSpan        ", "Hash Code" );
        Console.WriteLine( "{0,22}   {1,10}", 
            "--------        ", "---------" );

        DisplayHashCode( new TimeSpan( 0 ) );
        DisplayHashCode( new TimeSpan( 1 ) );
        DisplayHashCode( new TimeSpan( 0, 0, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 0, 1, 0 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0 ) );
        DisplayHashCode( new TimeSpan( 36000000001 ) );
        DisplayHashCode( new TimeSpan( 0, 1, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0, 0 ) );
        DisplayHashCode( new TimeSpan( 864000000001 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 1, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 100, 0, 0, 0 ) );
        DisplayHashCode( new TimeSpan( 100, 0, 0, 0, 1 ) );
        DisplayHashCode( new TimeSpan( 100, 0, 0, 1 ) );
    } 
}

備註

兩 TimeSpan 個物件可能具有相同的雜湊程式碼，即使它們代表不同的時間值也一樣。
