Visual Studio has provided us a great feature of code snippets , Code snippet is a "shortcut" to write large code with less key strokes 
for example if you want to write this 
MessageBox.Show("This is a msg"); 
you just have to write this 
mbox
 and press TAB two times 
see the magic , the mbox will turn into the larger text i.e 
 MessageBox.Show("message"); 
write your msg string here .. and save valuable keystrokes..
but its not the end 
there are many code snippets available in Visual Studio just like that one , just right click and point to "Insert Code snippet" and you will see the list of them ..
still want more...
just visit  
www.gotcodesnippets.net 
and download hundreds of ready-made snippets for your daily use..
still hungry for more :)
you can make your "own snippets" but i left it for your research ... you can find it in MSDN , its really a simple procedure. 
Waiting for research result ... :)
