VS 2010 mouse automation

问题

I am having an issue when using Microsoft.VisualStudio.TestTools.UITesting.Mouse. When I used as follow it gives me an exception saying "Object reference not set to an instance of an object".

Code

Microsoft.VisualStudio.TestTools.UITesting.Mouse.Click();  

I think I may have missed something. Can any body please provide me some good examples on this topic. Also please correct with my error code.
