.NET Framework 3.0
Returns the hash code for this string.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)

The following code example demonstrates the GetHashCode method using various input strings.
// Example for the String::GetHashCode( ) method. using namespace System; void DisplayHashCode( String^ Operand ) { int HashCode = Operand->GetHashCode(); Console::WriteLine( "The hash code for \"{0}\" is: 0x{1:X8}, {1}", Operand, HashCode ); } int main() { Console::WriteLine( "This example of String::GetHashCode( ) " "generates the following output.\n" ); DisplayHashCode( "" ); DisplayHashCode( "a" ); DisplayHashCode( "ab" ); DisplayHashCode( "abc" ); DisplayHashCode( "abd" ); DisplayHashCode( "abe" ); DisplayHashCode( "abcdef" ); DisplayHashCode( "abcdeg" ); DisplayHashCode( "abcdeh" ); DisplayHashCode( "abcdei" ); DisplayHashCode( "Abcdeg" ); DisplayHashCode( "Abcdeh" ); DisplayHashCode( "Abcdei" ); } /* This example of String::GetHashCode( ) generates the following output.
