public:
static bool operator <=(TimeSpan t1, TimeSpan t2);public static bool operator <= (TimeSpan t1, TimeSpan t2);static member ( <= ) : TimeSpan * TimeSpan -> boolPublic Shared Operator <= (t1 As TimeSpan, t2 As TimeSpan) As BooleanParameters
- t1
- TimeSpan
The first time interval to compare.
- t2
- TimeSpan
The second time interval to compare.
Returns
true if the value of t1 is less than or equal to the value of t2; otherwise, false.
Examples
The following example compares several TimeSpan objects to a reference TimeSpan using the LessThanOrEqual operator.
// Example of the TimeSpan relational operators.
