Gets or sets the element at the specified index.
Assembly: mscorlib (in mscorlib.dll)
List(T) accepts a null reference (Nothing in Visual Basic) as a valid value for reference types and allows duplicate elements.
This property provides the ability to access a specific element in the collection by using the following syntax: myCollection[index].
Retrieving the value of this property is an O(1) operation; setting the property is also an O(1) operation.
The following code example demonstrates the property (the indexer in C#) and various other properties and methods of the List(T) generic class. After the list has been created and populated using the Add method, an element is retrieved and displayed using the property.
Visual Basic, C#, and C++ all have syntax for accessing the property without using its name. Instead, the variable containing the List(T) is used as if it were an array.
The C# language uses the this keyword to define the indexers instead of implementing the property. Visual Basic implements as a default property, which provides the same indexing functionality.
For a code example that uses the property to set the value of a list element, see AsReadOnly.
