ReadOnlyMetadataCollection<T> Class

Definition

Represents a collection of members in the ADO.NET metadata hierarchy by providing a read-only collection with advanced lookup capabilities. This class is derived from the ReadOnlyCollection<T> class.

(Inherited from ReadOnlyCollection<T>)

Methods

Contains(String)

Determines whether the collection contains an item with the specified identity.

(Inherited from ReadOnlyCollection<T>)
CopyTo(T[], Int32)

Copies the entire ReadOnlyCollection<T> to a compatible one-dimensional Array, starting at the specified index of the target array.

(Inherited from ReadOnlyCollection<T>)
Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetEnumerator()

Returns an enumerator that can iterate through this collection.

GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
GetValue(String, Boolean)

Retrieves an item from this collection by using the specified identity.

IndexOf(T)

Returns the index of the specified value in this collection.

MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)

Explicit Interface Implementations

ICollection.CopyTo(Array, Int32)

Copies the elements of the ICollection to an Array, starting at a particular Array index.

(Inherited from ReadOnlyCollection<T>)
ICollection.IsSynchronized

Gets a value indicating whether access to the ICollection is synchronized (thread safe).

(Inherited from ReadOnlyCollection<T>)
ICollection.SyncRoot

Gets an object that can be used to synchronize access to the ICollection.

(Inherited from ReadOnlyCollection<T>)
ICollection<T>.Add(T)

Adds an item to the ICollection<T>. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
ICollection<T>.Clear()

Removes all items from the ICollection<T>. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
ICollection<T>.IsReadOnly

Gets a value indicating whether the ICollection<T> is read-only.

(Inherited from ReadOnlyCollection<T>)
ICollection<T>.Remove(T)

Removes the first occurrence of a specific object from the ICollection<T>. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
IEnumerable.GetEnumerator()

Returns an enumerator that iterates through a collection.

(Inherited from ReadOnlyCollection<T>)
IList.Add(Object)

Adds an item to the IList. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
IList.Clear()

Removes all items from the IList. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
IList.Contains(Object)

Determines whether the IList contains a specific value.

(Inherited from ReadOnlyCollection<T>)
IList.IndexOf(Object)

Determines the index of a specific item in the IList.

(Inherited from ReadOnlyCollection<T>)

IList.Item[Int32]

Gets the element at the specified index. A NotSupportedException occurs if you try to set the item at the specified index.

(Inherited from ReadOnlyCollection<T>)
IList.Remove(Object)

Removes the first occurrence of a specific object from the IList. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
IList.RemoveAt(Int32)

Removes the IList item at the specified index. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
IList<T>.Insert(Int32, T)

Inserts an item to the IList<T> at the specified index. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
IList<T>.Item[Int32]

Gets the element at the specified index. An NotSupportedException occurs if you try to set the item at the specified index.

(Inherited from ReadOnlyCollection<T>)
IList<T>.RemoveAt(Int32)

Removes the IList<T> item at the specified index. This implementation always throws NotSupportedException.

(Inherited from ReadOnlyCollection<T>)
