[RESOLVED] Uri.GetHashCode Unique?

[Chen.Fisher]

Hi,

Is the hashcode produced by the function Uri.GetHashCode unique? Can two different URIs produce the same hashcode?

A quote from Object.GetHashCode:
The default implementation of GetHashCode does not guarantee uniqueness or consistency

I would like to use the value of Uri.GetHashCode as a unique key in my DB and i have to be sure it is unique.

If you have a link to an article claiming it is unique, please refer me to it.

Thanks,
Chen.

Hash codes are generally not guaranteed to be unique.

To see why, have a look at:

The number of possible URLs if far bigger than the number of possible hash codes returned by the .net method.

Thanks, Zaccheus.
