You didn't specify a problem with your code. What is wrong with it? Do you expect us to figure out what is wrong with it and provide you the solution?

You need to realize we know nothing about what you are trying to accomplish nor can we see what is on your hard drive, I would suggest you use Improve question link on your post and update your question with a clearly defined explanation of your issue.

How to correct it below code

First step is to tell us why you think the code is wrong. We can't help you because we don't know what your code is supposed to do in first place.

There is a tool that allow you to see what your code is doing, its name is debugger. It is also a great learning tool because it show you reality and you can see which expectation match reality.
When you don't understand what your code is doing or why it does what it does, the answer is debugger.
Use the debugger to see what your code is doing. Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

Debugger - Wikipedia, the free encyclopedia[^]

Mastering Debugging in Visual Studio 2010 - A Beginner's Guide[^]
Basic Debugging with Visual Studio 2010 - YouTube[^]
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't find bugs, it just help you to. When the code don't do what is expected, you are close to a bug.
