The using Directive Can Create an Alias for a Type

You can use the using directive to create an alias for a namespace, which you can then use to access the types in that namespace.  For example:

1 2	using U1 = DogLibrary.Utility.StandardLogging; using U2 = DogLibrary.Utility.AlternateLogging;

We might do the above if we had an identically named type in each of the two namespaces so that we could then prefix the type with the appropriate namespace.

1 2	U1.DogLogger log1 = new U1.DogLogger(@"C:\log1.txt"); U2.DogLogger log2 = new U2.DogLogger(@"C:\log2.txt");

We can also use the using directive to create an alias for a specific type.  For the example above, we could do the following:

1 2	using Logger1 = DogLibrary.Utility.StandardLogging.DogLogger; using Logger2 = DogLibrary.Utility.AlternateLogging.DogLogger;

We could then use the alias directly as a type name:

1 2 3 4 5

// Short for DogLibrary.Utility.StandardLogging.DogLogger Logger1 log1 = new Logger1(@"C:\log1.txt");   // Short for DogLibrary.Utility.AlternateLogging.DogLogger Logger2 log2 = new Logger2(@"C:\log2.txt");
