Convert a method from java to C#.net

Question

I have a method in Java:

public int getInt() {
IntByReference ibr = new IntByReference();
if (CFLib.INSTANCE.CFNumberGetValue(this, 4, ibr))
  return ibr.getValue();
return -1;  }

here is the Reference:

http://developer.apple.com/iphone/library/documentation/CoreFoundation/Reference/CFNumberRef/Reference/reference.html

How I Can copy this exactly for C#.net?

That 4 there corresponds to the enum value kCFNumberSInt64Type. Why was that being jammed into a (32 bit) integer? Anyway, it looks like CFNumberGetValue wants a void* (C++) for its third parameter.

public int getInt() {
    int i;
    if (CFLib.INSTANCE.CFNumberGetValue(this, kCFNumberSInt32Type, (IntPtr)i))
        return i;
    return -1;
}

I don't know if anything needs to be done with the first parameter as I have no idea what this is.

The Problem is, there is no CFLib in C#, so i must find another method to do it. "This" is the value, which should be converted

If you're not going to use the Core Foundation library then just replace all CFNumber references and calls with equivalent C# primitives. It this case it looks like your entire class (whatever this is) should be replaced by an int (or long).
