TimeSpan.Compare Method

Compares two TimeSpan values and returns an integer that indicates their relationship.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public:
static int Compare (
	TimeSpan t1, 
	TimeSpan t2
)
public static int Compare (
	TimeSpan t1, 
	TimeSpan t2
)
public static function Compare (
	t1 : TimeSpan, 
	t2 : TimeSpan
) : int

Parameters

t1

A TimeSpan.

t2

A TimeSpan.

Return Value

Value

Condition

-1

t1 is less than t2

0

t1 is equal to t2

1

t1 is greater than t2

The following code example compares several TimeSpan objects to a reference TimeSpan using the Compare method.

// Example of the TimeSpan::Compare( TimeSpan, TimeSpan ) and 
// TimeSpan::Equals( TimeSpan, TimeSpan ) methods.
using namespace System;

// Compare TimeSpan parameters, and display them with the results.
void CompareTimeSpans( TimeSpan Left, TimeSpan Right, String^ RightText )
{
   String^ dataFmt = gcnew String( protoFmt );
   Console::WriteLine();
   Console::WriteLine( dataFmt, String::Concat( "Right: ", RightText ), Right );
   Console::WriteLine( dataFmt, "TimeSpan::Equals( Left, Right )", TimeSpan::Equals( Left, Right ) );
   Console::WriteLine( dataFmt, "TimeSpan::Compare( Left, Right )", TimeSpan::Compare( Left, Right ) );
}

int main()
{
   TimeSpan Left = TimeSpan(2,0,0);
   Console::WriteLine( "This example of the TimeSpan::Equals( TimeSpan, TimeSpan "
   ") and \nTimeSpan::Compare( TimeSpan, TimeSpan ) "
   "methods generates the \nfollowing output by creating "
   "several different TimeSpan \nobjects and comparing "
   "them with a 2-hour TimeSpan.\n" );
   Console::WriteLine( gcnew String( protoFmt ), "Left: TimeSpan( 2, 0, 0 )", Left );

   CompareTimeSpans( Left, TimeSpan(2,0,-1), "TimeSpan( 2, 0, -1 )" );
   CompareTimeSpans( Left, TimeSpan(72000000000), "TimeSpan( 72000000000 )" );
   CompareTimeSpans( Left, TimeSpan::FromDays( 1.0 / 12. ), "TimeSpan::FromDays( 1 / 12 )" );
