TimeSpan::FromSeconds Method
Returns a TimeSpan that represents a specified number of seconds, where the specification is accurate to the nearest millisecond.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Double
A number of seconds, accurate to the nearest millisecond.
| Exception | Condition |
|---|---|
| OverflowException | value is less than MinValue or greater than MaxValue. -or- value is Double::PositiveInfinity. -or- value is Double::NegativeInfinity. |
| ArgumentException | value is equal to Double::NaN. |
The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to intialize the new TimeSpan. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this can generate an OverflowException for values that are near but still in the range of either MinValue or MaxValue, This is the cause of an OverflowException, for example, in the following attempt to instantiate a TimeSpan object.
The following example creates several TimeSpan objects using the FromSeconds method.
// Example of the TimeSpan::FromSeconds( double ) method. using namespace System; void GenTimeSpanFromSeconds( double seconds ) { // Create a TimeSpan object and TimeSpan string from // a number of seconds. TimeSpan interval = TimeSpan::FromSeconds( seconds ); String^ timeInterval = interval.ToString(); // 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 = String::Concat( timeInterval, " " ); Console::WriteLine( "{0,21}{1,26}", seconds, timeInterval ); } int main() { Console::WriteLine( "This example of TimeSpan::FromSeconds( double )\n" "generates the following output.\n" ); Console::WriteLine( "{0,21}{1,18}", "FromSeconds", "TimeSpan" ); Console::WriteLine( "{0,21}{1,18}", "-----------", "--------" ); GenTimeSpanFromSeconds( 0.001 ); GenTimeSpanFromSeconds( 0.0015 ); GenTimeSpanFromSeconds( 12.3456 ); GenTimeSpanFromSeconds( 123456.7898 ); GenTimeSpanFromSeconds( 1234567898.7654 ); GenTimeSpanFromSeconds( 1 ); GenTimeSpanFromSeconds( 60 ); GenTimeSpanFromSeconds( 3600 ); GenTimeSpanFromSeconds( 86400 ); GenTimeSpanFromSeconds( 1801220.2 ); } /* This example of TimeSpan::FromSeconds( double ) generates the following output.
