Public method GetEnumerator(Int32, Int32) Returns an enumerator for a range of elements in the ArrayList.
Public method GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetRange Returns an ArrayList which represents a subset of the elements in the source ArrayList.
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method IndexOf(Object) Searches for the specified Object and returns the zero-based index of the first occurrence within the entire ArrayList.
Public method IndexOf(Object, Int32) Searches for the specified Object and returns the zero-based index of the first occurrence within the range of elements in the ArrayList that extends from the specified index to the last element.
Public method IndexOf(Object, Int32, Int32) Searches for the specified Object and returns the zero-based index of the first occurrence within the range of elements in the ArrayList that starts at the specified index and contains the specified number of elements.
Public method Insert Inserts an element into the ArrayList at the specified index.
Public method InsertRange Inserts the elements of a collection into the ArrayList at the specified index.
Public method LastIndexOf(Object) Searches for the specified Object and returns the zero-based index of the last occurrence within the entire ArrayList.
Public method LastIndexOf(Object, Int32) Searches for the specified Object and returns the zero-based index of the last occurrence within the range of elements in the ArrayList that extends from the first element to the specified index.
Public method LastIndexOf(Object, Int32, Int32) Searches for the specified Object and returns the zero-based index of the last occurrence within the range of elements in the ArrayList that contains the specified number of elements and ends at the specified index.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method Static member ReadOnly(ArrayList) Returns a read-only ArrayList wrapper.
Public method Static member ReadOnly(IList) Returns a read-only IList wrapper.
Public method Remove Removes the first occurrence of a specific object from the ArrayList.
Public method RemoveAt Removes the element at the specified index of the ArrayList.

Public method Reverse() Reverses the order of the elements in the entire ArrayList.
Public method Reverse(Int32, Int32) Reverses the order of the elements in the specified range.
Public method SetRange Copies the elements of a collection over a range of elements in the ArrayList.
Public method Sort() Sorts the elements in the entire ArrayList.
Public method Sort(IComparer) Sorts the elements in the entire ArrayList using the specified comparer.
Public method Sort(Int32, Int32, IComparer) Sorts the elements in a range of elements in ArrayList using the specified comparer.
Public method Static member Synchronized(ArrayList) Returns an ArrayList wrapper that is synchronized (thread safe).
Public method Static member Synchronized(IList) Returns an IList wrapper that is synchronized (thread safe).
Public method ToArray() Copies the elements of the ArrayList to a new Object array.
Public method ToArray(Type) Copies the elements of the ArrayList to a new array of the specified element type.
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Public method TrimToSize Sets the capacity to the actual number of elements in the ArrayList.
