TimeSpan 以下演算子

2008-03-28

指定した TimeSpan が、指定したもう 1 つの TimeSpan 以下かどうかを示します。

returnValue = TimeSpan.op_LessThanOrEqual(t1, t2)
[C#]
public static bool operator <=(TimeSpant1,TimeSpant2);
[C++]
public: static bool op_LessThanOrEqual(TimeSpant1,TimeSpant2);
[JScript]
returnValue = t1 <= t2;

[Visual Basic] Visual Basic では、この型で定義されている演算子を使用することができます。ただし、独自に定義することはできません。Compare メソッドを TimeSpan 以下演算子の代わりに使用することができます。

[JScript] JScript では、この型で定義されている演算子を使用することができます。ただし、独自に定義することはできません。

引数 [Visual Basic, JScript]

t1
TimeSpan 。
t2
TimeSpan 。

パラメータ [C#, C++]

t1
TimeSpan 。
t2
TimeSpan 。

戻り値

t1 の値が t2 の値以下の場合は true 。それ以外の場合は false 。

使用例

[Visual Basic, C#, C++] LessThanOrEqual 演算子を使用して、複数の TimeSpan オブジェクトを TimeSpan の参照値と比較するコード例を次に示します。
