How to use Function After Calling GetProcAddress()

[vanta]

Hi everyone.

I don't know to use Function(...) after calling GetProcAddress(hmodule, Function(...))

My code :
DllImport("Kernel32.dll")]
public static extern System.IntPtr LoadLibrary(string NameDLL);

DllImport("Kernel32.dll")]
public static extern System.IntPtr GetProcAddress( IntPtr hModule, string FunctionName);
.......

IntPtr temp = LoadLibrary("MyDLL.DLL");

"?" = GetProcAddress( temp, "FunctionName");
....

How to use "FunctionName" ?

please tell me.

thank you.
