Properties

CacheSize	Gets or sets the size of the cache used to store data from the file in memory.
Count	Gets the number of elements contained in the FileBackedHashSetT.
DefaultSignature	Gets the default signature used by the FileBackedHashSetT if no user-defined signature is supplied.
FilePath	Gets or sets the path to the file backing this hash set.
FragmentationCount	Gets the number of operations that fragment the lookup table that have occurred since the last time the lookup table was compacted.
IsReadOnly	Gets a value indicating whether the FileBackedHashSetT is read-only.
Signature	Gets or sets the signature of the file backing the lookup table.

Methods

Add	Adds an element to the current set and returns a value to indicate if the element was successfully added.
Clear	Removes all items from the FileBackedHashSetT.
Close	Closes the file backing this hash set.
Compact	Defragments the item section of the hash set, which gets fragmented after removing items.
Contains	Determines whether the FileBackedHashSetT contains a specific value.
CopyTo	Copies the elements of the FileBackedHashSetT to an Array, starting at a particular Array index.
Dispose	Releases all the resources used by the FileBackedHashSetT object.
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
ExceptWith	Removes all elements in the specified collection from the current set.
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
GetEnumerator	Returns an enumerator that iterates through the collection.
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
IntersectWith	Modifies the current set so that it contains only elements that are also in a specified collection.
IsProperSubsetOf	Determines whether the current set is a proper (strict) subset of a specified collection.
IsProperSupersetOf	Determines whether the current set is a proper (strict) superset of a specified collection.
IsSubsetOf	Determines whether a set is a subset of a specified collection.
IsSupersetOf	Determines whether the current set is a superset of a specified collection.
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
Open	Opens the file backing this hash set.
OpenRead	Opens the file backing this hash set in read-only mode.
Overlaps	Determines whether the current set overlaps with the specified collection.
Remove	Removes the first occurrence of a specific object from the FileBackedHashSetT.
RemoveWhere	Removes all elements that match the conditions defined by the specified predicate from a FileBackedHashSetT collection.
SetEquals	Determines whether the current set and the specified collection contain the same elements.
SymmetricExceptWith	Modifies the current set so that it contains only elements that are present either in the current set or in the specified collection, but not both.
ToString	Returns a string that represents the current object. (Inherited from Object)
UnionWith	Modifies the current set so that it contains all elements that are present in either the current set or the specified collection.
