First up, please post in the most appropriate forum for the topic. This question is not relevant to Windows Forms so it doesn't belong in the Windows Forms forum.

As for the question, the DllImport attribute is used to declare a proxy method that you can call to invoke a function that has been declared in and exported from an unmanaged DLL. Such a DLL would most often be written in C++ or perhaps C, but may be in done in any unmanaged language that supports it. Functions called this way are most commonly part of the Windows API, i.e. the DLLs that make up the Win32 programming interface, but many other libraries can be used in the same way.
