First you have to add reference of the dll.
  1. Right click the project name
  2. Add reference -> .net tab and then choose namespace then press ok button.
  3. In .aspx code behind file you have to import the System.Windows.Forms namespace and that’s it.
By customizing parameters used in CopyFromScreen() function, you can figure out how to capture the small portion of the screen, if required. Create a folder and give folder path in c# code just like above i have given. You can customize the code as well and give the dynamic name of bitmap file every time it is generated.
