   const uchar  value        // value
   );

A version for working with the short type.

int GetHashCode(
   const short  value        // value
   );

A version for working with the ushort type.

A version for working with the string type.

int GetHashCode(
   const string  value       // value
   );

A version for working with other types.

template<typename T>
int GetHashCode(
   T  value                  // value
   );

Parameters

value

[in]  The value for which you want to get the hash code.

Return Value

Returns the hash code.

Note

If the T type is an object that implements the IEqualityComparable<T> interface, then the hash code will be obtained based on its HashCode method. In all other cases, the hash code will be calculated as the hash value of the value type name.
