Using Namespace Aliases in .NET

In most cases, when there are namespace conflicts, developers tend to use the complete qualified name in the code. For example:

using System.Web.UI.WebControls;
using MyComponent.Web.UI.WebControls;
This is usually okay for simple class files—assuming that there is a Calendar class in both namespaces and you need to use the custom class in many sections of the class.

However, instead of specifying the fully qualified name, you could also give an alias for the namespace and make use of it everywhere, like this:

using System.Web.UI.WebControls;
using MyControls = MyComponent.Web.UI.WebControls;
Then, instead of using the fully-qualified name like this:

MyComponent.Web.UI.WebControls.Calender cal = 
new MyComponent.Web.UI.WebControls.Calender();
You'd be able to use the shorter aliased name, like this:

MyControls.Calender  cal = new MyControls.Calender();
