Assembly:  System.Web.ApplicationServices (in System.Web.ApplicationServices.dll)

public ref class MembershipUserCollection sealed : IEnumerable, 

The MembershipUserCollection type exposes the following members.

Public methodMembershipUserCollectionCreates a new, empty membership user collection.

Public propertyCountGets the number of membership user objects in the collection.
Public propertyIsSynchronizedGets a value indicating whether the membership user collection is thread safe.
Public propertyItemGets the membership user in the collection referenced by the specified user name.
Public propertySyncRootGets the synchronization root.

Public methodAddAdds the specified membership user to the collection.
Public methodClearRemoves all membership user objects from the collection.
Public methodCopyToCopies the membership user collection to a one-dimensional array.
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetEnumeratorGets an enumerator that can iterate through the membership user collection.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodRemoveRemoves the membership user object with the specified user name from the collection.
Public methodSetReadOnlyMakes the contents of the membership user collection read-only.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodAsParallelEnables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension MethodAsQueryableConverts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension MethodCast<TResult>Casts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodOfType<TResult>Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)

Explicit interface implemetationPrivate methodICollection::CopyToCopies the contents of the MembershipUserCollection object to an Array, starting at a particular Array index.

A System.Web.Security::MembershipUserCollection is returned from the GetAllUsers, FindUsersByName, and FindUsersByEmail methods of the System.Web.Security::Membership class. The MembershipUserCollection objects returned by the GetAllUsers, FindUsersByName, and FindUsersByEmail methods contain a snapshot of user information in the membership data store. That is, changes to the membership user information in a MembershipUserCollection are not reflected in the membership data store. To modify membership user information in the membership data store, use the UpdateUser, CreateUser and DeleteUser methods of the System.Web.Security::Membership class.
