关于c#中指针

Question

我在调用一个delphi的动态库时，遇到一个函数需要我传入IP地址的指针。在c#中我不知道用什么可以把这个IP地址转换为指针。请各位帮忙。谢谢

Answer 1

[C#]
using System.Runtime.InteropServices;
[StructLayout(LayoutKind.Sequential)]
public struct Point {
public int x;
public int y;
} 

[StructLayout(LayoutKind.Explicit)]
public struct Rect {
[FieldOffset(0)] public int left;
[FieldOffset(4)] public int top;
[FieldOffset(8)] public int right;
[FieldOffset(12)] public int bottom;
} 

class Win32API {
[DllImport("User32.dll")]
public static extern bool PtInRect(ref Rect r, Point p);
}

Answer 2

char *吗? 直接string类型就可以了
