Určuje, zda TimeSpan jsou dvě instance stejné.
public:
static bool operator ==(TimeSpan t1, TimeSpan t2);
public static bool operator == (TimeSpan t1, TimeSpan t2);
static member ( = ) : TimeSpan * TimeSpan -> bool
Public Shared Operator == (t1 As TimeSpan, t2 As TimeSpan) As Boolean
Parametry
- t1
- TimeSpan
První časový interval pro porovnání.
- t2
- TimeSpan
Druhý časový interval pro porovnání.
Návraty
true
jsou-li hodnoty t1
a t2
jsou stejné, v opačném případě false
.
