Properties
Name | Description | |
---|---|---|
Count | Gets the number of elements contained in the ReadOnlyCollection<T> instance. (Inherited from ReadOnlyCollection<TTargetElement>.) | |
Item | Gets the element at the specified index. (Inherited from ReadOnlyCollection<TTargetElement>.) | |
Items | Returns the IList<T> that the ReadOnlyCollection<T> wraps. (Inherited from ReadOnlyCollection<TTargetElement>.) |

Methods
Name | Description | |
---|---|---|
Contains | Determines whether an element is in the ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<TTargetElement>.) | |
CopyTo | Copies the entire ReadOnlyCollection<T> to a compatible one-dimensional Array, starting at the specified index of the target array. (Inherited from ReadOnlyCollection<TTargetElement>.) | |
Dispose() | Tears down all elements of the transformed collection, clears the transformed collection, and stops listening to change events on the source collection. | |
Dispose(Boolean) | ||
Equals | 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 enumerator that iterates through the ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<TTargetElement>.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IndexOf | Searches for the specified object and returns the zero-based index of the first occurrence within the entire ReadOnlyCollection<T>. (Inherited from ReadOnlyCollection<TTargetElement>.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
OnCollectionChanged | ||
OnPropertyChanged | ||
ReceiveWeakEvent | ||
ToString | Returns a string that represents the current object. (Inherited from Object.) |
