[导入]这段时间都是搞那个华为的API

调用华为的DLL，我在网上找了一下都没有很理想的例子。这几天自己弄了一下。有了点结果。该DLL是C++写的。我用C#来调用成功了。下面是函数声明。

[DllImport("SMEIDll.dll")]
public extern static bool IFInitInterface(int dwCodeProtocol,int dwDriverProtocol,string pDriverParam);

[DllImport("SMEIDll.dll")]
public extern static bool IFExitInterface();

[DllImport("SMEIDll.dll")]
public extern static bool Login_R(string SystemID, string Password);
