A 32-bit signed integer hash code.
Examples
The following example generates the hash codes of several TimeSpan objects using the GetHashCode method.
// Example for the TimeSpan::GetHashCode( ) method.
using namespace System;
void DisplayHashCode( TimeSpan interval )
{
// Create a hash code and a string representation of
// the TimeSpan parameter.
String^ timeInterval = interval.ToString();
int hashCode = interval.GetHashCode();
// 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( "{0,22} 0x{1:X8}, {1}", timeInterval, hashCode );
}
int main()
{
Console::WriteLine( "This example of TimeSpan::GetHashCode( ) generates "
"the following \noutput, which displays "
"the hash codes of representative TimeSpan \n"
"objects in hexadecimal and decimal formats.\n" );
Console::WriteLine( "{0,22} {1,10}", "TimeSpan ", "Hash Code" );
