Parameters

index
Type: System.Int32

The zero-based index of the entry to locate in the collection.

Property Value

Type: System.String

The String key of the entry at the specified index of the collection.

Exception Condition
ArgumentOutOfRangeException

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] (In Visual Basic, myCollection(index)).

The C# language uses the 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 value of this property is an O(1) operation; setting the property is also an O(1) operation.
