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. |
This property allows access to a specific item in the collection by using the following syntax: myCollection[index], where index is the specified TargetFormatType enumeration type. 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.
