NameValueCollection.Item Property (Int32)

Gets the entry at the specified index of the NameValueCollection.

Namespace:  System.Collections.Specialized
Assembly:  System (in System.dll)

member Item : string


Type: System.Int32
The zero-based index of the entry to locate in the collection.

Property Value

Type: System.String
A String that contains the comma-separated list of values at the specified index of the collection.


index is outside the valid range of indexes for the collection.

This property provides the ability to access a specific element in the collection by using the following syntax: myCollection[index].

This property cannot be set. To set the value at a specified index, use Item[GetKey(index)].

The C# language uses the this keyword to define the indexers instead of implementing the Item property. Visual Basic implements Item as a default property, which provides the same indexing functionality.

Retrieving the values at the specified index is an O(n) operation, where n is the number of values.
