In Microsoft speak this is "Calling Unmanaged Code from a Managed Application."
Try google.com search terms: c# call native dll

How do you directly call a native function exported from a DLL? -
Here?s a quick example of the DllImport attribute in action:
using System.Runtime.InteropServices;
class C
{
[DllImport("user32.dll")]
public static extern int MessageBoxA(int h, string m, string c, int type);
public static int Main()
{
return MessageBoxA(0, "Hello World!", "Caption", 0);
}
}
This example shows the minimum requirements for declaring a C# method
that is implemented in a native DLL. The method C.MessageBoxA() is
declared with the static and external modifiers, and has the DllImport
attribute, which tells the compiler that the implementation comes from
the user32.dll, using the default name of MessageBoxA. For more
information, look at the Platform Invoke tutorial in the
documentation.

Not that this is going to work automatically, but this is the path
you'll need to start down. If you need further help, try posting info
