Syntax
public class SFArrayList : ArrayList, IList, ICollection, IEnumerable, ICloneable

Constructors

SFArrayList()

Overloaded. Initializes a new instance of the SFArrayList class that is empty and has the default initial capacity.

Declaration
public SFArrayList()

SFArrayList(ICollection)

Initializes a new instance of the SFArrayList class that contains elements copied from the specified collection and has the same initial capacity as the number of elements copied.

Declaration
public SFArrayList(ICollection c)
Parameters
Type Name Description
System.Collections.ICollection c

The System.Collections.ICollection whose elements are copied to the new list.

Properties

Item[Int32]

Gets / sets the element at the specified index. In C#, this property is the indexer for the SFArrayList class.

Declaration
public override object this[int index] { get; set; }
Parameters
Type Name Description
System.Int32 index

The zero-based index of the element to get / set.
Property Value
Type Description
System.Object

The element at the specified index. When querying the value and the index is out of range, an empty (null) object will be returned. When setting the value and the index is out of range the array will be enlarged. See EnsureCount(Int32)
Overrides
System.Collections.ArrayList.Item[System.Int32]

Methods

Clone()

Overridden. Creates a deep copy of the SFArrayList.

Declaration
public override object Clone()
Returns
Type Description
System.Object

A deep copy of the SFArrayList.
Overrides
System.Collections.ArrayList.Clone()

EnsureCount(Int32)

Enlarges the array if needed.

Declaration
public void EnsureCount(int value)
Parameters
Type Name Description
System.Int32 value

The size to be checked. If the array has less elements, empty (null) objects will be appended at the end of the array.

InsertRange(Int32, Int32)

Inserts a specified number of (null) values in the SFArrayList at a given index.

Declaration
public void InsertRange(int index, int count)
Parameters
Type Name Description
System.Int32 index

The zero-based index of the first value to be inserted.
System.Int32 count

The number of values in the range to be added.
Examples
SFArrayList array = new SFArrayList();
array[0] = 0;
array[1] = 1;
array[2] = 2;
array[3] = 3;
array.InsertRange(1, 2);
// results in new order: 0, null, null, 2, 3

MoveRange(Int32, Int32, Int32)

Rearranges the values in the SFArrayList.

Declaration
public void MoveRange(int index, int count, int dest)
Parameters
Type Name Description
System.Int32 index

The zero-based index of the first value to be moved.
System.Int32 count

The number of values in the range to be moved.
System.Int32 dest

The new starting index for the range. The zero-based index is based on the original array.
Examples
SFArrayList array = new SFArrayList();
array[0] = 0;
array[1] = 1;
array[2] = 2;
array[3] = 3;
array.MoveRange(0, 2, 3);
// results in new order: 2, 0, 1, 3

RemoveRange(Int32, Int32)

Removes a range of values from the SFArrayList.

Declaration
public override void RemoveRange(int index, int count)
Parameters
Type Name Description
System.Int32 index

The zero-based index of the first value to be removed.
System.Int32 count

The number of values in the range to be removed.
Overrides
System.Collections.ArrayList.RemoveRange(System.Int32, System.Int32)
Examples
SFArrayList array = new SFArrayList();
array[0] = 0;
array[1] = 1;
array[2] = 2;
array[3] = 3;
array.RemoveRange(1, 2);
// results in new order: 0, 3
