Examples

This section provides two code examples. The first demonstrates how to declaratively specify values for several properties of the AssemblyCollection class. The second demonstrates how to use members of the AssemblyCollection class.

The following configuration file example shows how to declaratively specify values for several properties of the AssemblyCollection class.

Remarks

The AssemblyCollection class does not refer to any actual element in the underlying configuration file. It is a construct that allows access to the assembly information it contains.

Constructors
