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 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. Compressor names are unique. An application can use this method to find a specific compressor. A Compressor's name can be retrieved with the Compressor.Name property or by using the LTMM DirectShow Filter List Utility. If the method fails, an error is raised.
For more information, refer to the Error Codes.
