Exceptions
Exception | Description |
---|---|
System.ArgumentOutOfRangeException | The exception that is thrown when the value of an argument is outside the allowable range of values as defined by the invoked method. |
System.NullReferenceException | The exception that is thrown when there is an attempt to dereference a null object reference. |
This property provides the ability to access a specific item in the collection by using the following syntax: myCollection[index]
The C# language uses the this keyword to define the indexers instead of implementing the Item property. VB implements Item as a default property, which provides the same indexing functionality.
