![]() | Clear | Removes all items from the collection. (Inherited from ProviderCollection.) |
![]() | CopyTo(MembershipProvider(), Int32) | Copies the membership provider collection to a one-dimensional array. |
![]() | CopyTo(ProviderBase(), Int32) | Copies the contents of the collection to the given array starting at the specified index. (Inherited from ProviderCollection.) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | 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 object that implements the IEnumerator interface to iterate through the collection. (Inherited from ProviderCollection.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | Remove | Removes a provider from the collection. (Inherited from ProviderCollection.) |
![]() | SetReadOnly | Sets the collection to be read-only. (Inherited from ProviderCollection.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |

![]() ![]() | ICollection.CopyTo | Copies the elements of the ProviderCollection to an array, starting at a particular array index. (Inherited from ProviderCollection.) |
The membership providers for an application are exposed as a read-only MembershipProviderCollection by the Providers property of the Membership class. You can access a specific membership provider in the collection by name and cast it as the specific provider type, such as SqlMembershipProvider. This enables you to manage membership information from multiple data stores in a single application as well as access custom members of a membership provider that are not part of the MembershipProvider abstract class.
