And what is your question..? :-)
You are not doing anything with str1, str2. And we don't know what is in the lines of your text box and why. It all has very little to no sense...

Perhaps you should switch from what you doing to some conscious programming. So far, this is not programming at all. In programming, you should understand what you are doing, every character you enter. Let's see.

In the loop, you create a string from TextBox2.Lines(x) by calling, actually string.ToString. It works, because all type have the method System.Object.ToString. But why making an identical string from string? It is already a string. Same thing in the next two lines. Now, what's the purpose of str1 and str2? When you exit each iteration of your loop, these two values are lost and the object are discarded, will eventually be destructed by the Garbage Collection.

This is not programming and not the way to learn programming. If you get some code, I doubt it will teach you to write your own. Perhaps you need to try even simpler exercises (how it can be even simpler than this one? I don't know; probably it can be; it depends on your level of understanding), but do them the way you would really understand each your step.
