名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Overrides Function
 GetHashCode As Integer

Visual Basic (使用法)

Dim instance As TimeSpan
Dim returnValue As Integer

returnValue = instance.GetHashCode

C#

public override int GetHashCode ()

C++

public:
virtual int GetHashCode () override

J#

public int GetHashCode ()

JScript

public override function GetHashCode () : int

戻り値
32 ビット符号付き整数ハッシュ コード。

解説

2 つの TimeSpan オブジェクトが、異なる時間値を表していても、同じハッシュ コードを持つ場合があります。

使用例

GetHashCode メソッドを使用して、複数の TimeSpan オブジェクトのハッシュ コードを生成するコード例を次に示します。
