Exceptions
Exception | Description |
---|---|

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.
Capture Input names are unique. An application can use this method to find a specific input. A Capture Input name can be retrieved with the CaptureInput.Name property. If the method fails, an error will be raised.
For more information, refer to the Error Codes.
