TimeSpan::CompareTo Method (Object)

Compares this instance to a specified object and returns an integer that indicates whether this instance is shorter than, equal to, or longer than the specified object.

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

public:
virtual int CompareTo(
	Object^ value
) sealed

Parameters

value
Type: System::Object
An object to compare, or nullptr.

Return Value

Type: System::Int32
One of the following values.

Value

Description

-1

This instance is shorter than value.

0

This instance is equal to value.

1

This instance is longer than value.

-or-

value is nullptr.

Implements

IComparable::CompareTo(Object)

ExceptionCondition
ArgumentException

value is not a TimeSpan.

Any instance of TimeSpan, regardless of its value, is considered greater than nullptr.

The value parameter must be an instance of TimeSpan or nullptr; otherwise, an exception is thrown.

The following example compares several TimeSpan structures and other objects to a reference TimeSpan structure using the CompareTo method.


// Example of the TimeSpan::CompareTo( Object* ) and 
// TimeSpan::Equals( Object* ) methods.
using namespace System;

// Compare the TimeSpan to the Object parameters, 
// and display the Object parameters with the results.
void CompTimeSpanToObject( TimeSpan Left, Object^ Right, String^ RightText )
{
   Console::WriteLine( "{0,-33}{1}", String::Concat( "Object: ", RightText ), Right );
   Console::WriteLine( "{0,-33}{1}", "Left.Equals( Object )", Left.Equals( Right ) );
   Console::Write( "{0,-33}", "Left.CompareTo( Object )" );

   // Catch the exception if CompareTo( ) throws one.
   try
   {
      Console::WriteLine( "{0}\n", Left.CompareTo( Right ) );
   }
   catch ( Exception^ ex ) 
   {
      Console::WriteLine( "Error: {0}\n", ex->Message );
   }

}

int main()
{
   TimeSpan Left = TimeSpan(0,5,0);
   Console::WriteLine( "This example of the TimeSpan::Equals( Object* ) "
   "and \nTimeSpan::CompareTo( Object* ) methods generates "
   "the \nfollowing output by creating several different "
   "TimeSpan \nobjects and comparing them with a "
   "5-minute TimeSpan.\n" );
   Console::WriteLine( "{0,-33}{1}\n", "Left: TimeSpan( 0, 5, 0 )", Left );

   // Create objects to compare with a 5-minute TimeSpan.
   CompTimeSpanToObject( Left, TimeSpan(0,0,300), "TimeSpan( 0, 0, 300 )" );
   CompTimeSpanToObject( Left, TimeSpan(0,5,1), "TimeSpan( 0, 5, 1 )" );
   CompTimeSpanToObject( Left, TimeSpan(0,5,-1), "TimeSpan( 0, 5, -1 )" );
   CompTimeSpanToObject( Left, TimeSpan(3000000000), "TimeSpan( 3000000000 )" );
   CompTimeSpanToObject( Left, 3000000000L, "__int64 3000000000L" );
   CompTimeSpanToObject( Left, "00:05:00", "String \"00:05:00\"" );
}
