Decimal.GetHashCode Method
.NET Framework 1.1
Returns the hash code for this instance.
[Visual Basic] Overrides Public Function GetHashCode() As Integer [C#] public override int GetHashCode(); [C++] public: int GetHashCode(); [JScript] public override function GetHashCode() : int;
Return Value
A 32-bit signed integer hash code.
Example
[Visual Basic, C#, C++] The following code example uses the GetHashCode method to return the hash codes of several Decimal values.
