Return Value
An integer that contains the hash code for the object. Two FormDefinitionCollection objects whose FormDefinition objects have different template image hash codes will almost always have different template image hash codes.
This method computes and returns a hash code for this object. Unlike the GetHashCode method, this method is not intended for use in a hash table or other similar data structure. Instead, you can use it to determine when template images in this object have changed. Specifically, this method examines the template images of the forms in the collection and their ordering, which affects form identification.
