Syntax

public class ReadOnlyStringList : IList<string>, ICollection<string>, IEnumerable<string>, IEnumerable

Constructors

ReadOnlyStringList(IList<String>)

Initializes a new instance of the ReadOnlyStringList class.

Declaration

public ReadOnlyStringList(IList<string> items)

Parameters

Type	Name	Description
System.Collections.Generic.IList<System.String>	items	The items.

Properties

Count

Gets the number of elements contained in the System.Collections.Generic.ICollection<T>.

Declaration

public int Count { get; }

Property Value

Type	Description
System.Int32

IsReadOnly

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

Declaration

public bool IsReadOnly { get; }

Property Value

Type	Description
System.Boolean

Item[Int32]

Gets or the System.String at the specified index. Set is not a valid operation on a readonly list. Will throw InvalidOperationException;

Declaration

public string this[int index] { get; set; }

Parameters

Type	Name	Description
System.Int32	index

Property Value

Type	Description
System.String

Methods

Add(String)

Not a valid operation on a readonly list. Will throw InvalidOperationException;

Declaration

public void Add(string item)

Parameters

Type	Name	Description
System.String	item	The object to add to the System.Collections.Generic.ICollection<T>.

Exceptions

Type	Condition
System.NotSupportedException	The System.Collections.Generic.ICollection<T> is read-only.

Clear()

Not a valid operation on a readonly list. Will throw InvalidOperationException;

Declaration

public void Clear()

Exceptions

Type	Condition
System.NotSupportedException	The System.Collections.Generic.ICollection<T> is read-only.

Contains(String)

Determines whether the System.Collections.Generic.ICollection<T> contains a specific value. The compairson will be performed on upper invariant case.

Declaration

public bool Contains(string item)

Parameters

Type	Name	Description
System.String	item	The object to locate in the System.Collections.Generic.ICollection<T>.

Returns

Type	Description
System.Boolean	true if `item` is found in the System.Collections.Generic.ICollection<T>; otherwise, false.

CopyTo(String[], Int32)

Copies the elements of the System.Collections.Generic.ICollection<T> to an System.Array, starting at a particular System.Array index.

Declaration

public void CopyTo(string[] array, int arrayIndex)

Parameters

Type	Name	Description
System.String[]	array	The one-dimensional System.Array that is the destination of the elements copied from System.Collections.Generic.ICollection<T>. The System.Array must have zero-based indexing.
System.Int32	arrayIndex	The zero-based index in `array` at which copying begins.

Exceptions

Type	Condition
System.ArgumentNullException	`array` is null.
System.ArgumentOutOfRangeException	`arrayIndex` is less than 0.
System.ArgumentException	`array` is multidimensional.-or-`arrayIndex` is equal to or greater than the length of `array`.-or-The number of elements in the source System.Collections.Generic.ICollection<T> is greater than the available space from `arrayIndex` to the end of the destination `array`.-or-Type cannot be cast automatically to the type of the destination `array`.

GetEnumerator()

Returns an enumerator that iterates through the collection.

Declaration

public IEnumerator<string> GetEnumerator()

Returns

Type	Description
System.Collections.Generic.IEnumerator<System.String>	A System.Collections.Generic.IEnumerator<T> that can be used to iterate through the collection.

IndexOf(String)

Determines the index of a specific item in the System.Collections.Generic.IList<T>.

Declaration

public int IndexOf(string item)

Parameters

Type	Name	Description
System.String	item	The object to locate in the System.Collections.Generic.IList<T>.

Returns

Type	Description
System.Int32	The index of `item` if found in the list; otherwise, -1.

Insert(Int32, String)

Not a valid operation on a readonly list. Will throw InvalidOperationException;

Declaration

public void Insert(int index, string item)

Parameters

Type	Name	Description
System.Int32	index	The zero-based index at which `item` should be inserted.
System.String	item	The object to insert into the System.Collections.Generic.IList<T>.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException	`index` is not a valid index in the System.Collections.Generic.IList<T>.
System.NotSupportedException	The System.Collections.Generic.IList<T> is read-only.

Remove(String)

Not a valid operation on a readonly list. Will throw InvalidOperationException;

Declaration

public bool Remove(string item)

Parameters

Type	Name	Description
System.String	item	The object to remove from the System.Collections.Generic.ICollection<T>.

Returns

Type	Description
System.Boolean	true if `item` was successfully removed from the System.Collections.Generic.ICollection<T>; otherwise, false. This method also returns false if `item` is not found in the original System.Collections.Generic.ICollection<T>.

Exceptions

Type	Condition
System.NotSupportedException	The System.Collections.Generic.ICollection<T> is read-only.

RemoveAt(Int32)

Not a valid operation on a readonly list. Will throw InvalidOperationException;

Declaration

public void RemoveAt(int index)

Parameters

Type	Name	Description
System.Int32	index	The zero-based index of the item to remove.
