how can i create dynamic lable in C#.net windows application ??

This is a pretty concise example. Replace the textbox with label controls and you should be on your way. Please note that properties are a little bit different but this will explain how you do it.

You can do that: drag a Label named lbTest. And Find lbTest in the design file. And copy that part of code into where you want to create the label. Remember to rename the control.
