Type.GetHashCode Method
.NET Framework 3.0
Returns the hash code for this instance.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
This method overrides Object.GetHashCode.
The following example displays the hash code of the System.Windows.Forms.Button class.
