Constructors

ReadOnlyStringList(IList<String>)

Initializes a new instance of the ReadOnlyStringList class.

Declaration
public ReadOnlyStringList(IList<string> items)
Parameters
Type Name Description

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; }

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>.

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()
