我最近做了一个调用迅雷下载软件。不过迅雷是C写得，我不懂C，求高手帮我把这个转成C#代码。谢谢了。

------解决思路----------------------
PInvoke，使用DllImport把相应的api转换成c#就可以了。
www.pinvoke.net 这个网很全
------解决思路----------------------
吧dll文件interop进来，关于类型转换参考下边这个：
http://blog.csdn.net/kfqcome/article/details/10158689
------解决思路----------------------
BOOL->int
MAX_PATH=260
wchar_t -> char
wchar_t [] -> char[] -> string
__int64 -> long
INT32->int
extern "C" __declspec(dllimport) // 以__cdcel方式导入函数(以C方式导入，因为这个破DLL是C语言编写的，C++要导入的写好约定)
memset(this, 0, sizeof(DownTaskInfo));
// 把自己块内存全部清零，说实话用这破函数还不如用 ZeroMemory / RtlZeroMemory
------解决思路----------------------
Handle是个句柄，
Handle->SysInt->IntPtr->int
- - 不过她这个句柄有些高端，我琢磨着估计是(C.Object)对象的指针地址
