Adding an Exception

To add a new exception class to the driver

1. From Solution Explorer, double-click the Driver Designer node under the Nimbus node.

2. The IVI.NET Driver Designer tree view opens.

3. Expand the root node, which will be named after the driver assembly (e.g.: Acme.Acme4321).

4. Right-click on the Exceptions node and select Add Exception.

5. A new exception class is added with a default name and the tree node enters edit mode. Type the desired name for the new exception class and hit the Enter key.

   When choosing the name for a new exception class, the following naming rules apply:

   • The name must be unique within the driver.
   • The name must contain only alphanumeric characters, and must start with an alphabetic character.
   • Spaces are not allowed.

   Note

   To define a generic exception class, specify the generic type parameter(s) as part of the exception class name, for example Acme4321Exception\<T, U\>.

   Refer to Understanding Type Name Resolution in Nimbus for more information about type name resolution and generics in Nimbus.

6. The new exception class will be defined in a file named \<exceptionName\>.cs that Nimbus will automatically add to the driver project.

   After the exception class is added, the Exception General Editor appears in the right portion of the IVI.NET Driver Designer.
