网络接口库函数mpr.dll动态库

今天看到项目中使用了下面的方式挂载本地磁盘驱动，映射网络共享目录：

[DllImport("mpr.dll", EntryPoint = "WNetAddConnection2")]
private static extern uint WNetAddConnection2(NetResource lpNetResource, string lpPassword, string lpUsername, uint dwFlags);

于是，上网查询相关接口，参数等调用情况，发现网上很多都是自己总结，总感觉都不够全面，还是看官方说明文档吧！

===========================================================================

从网上找来一个，对方法进行了部分修改，参考使用

映射Z盘的调用格式：

const string netWorkPath = @"\\192.168.1.120\共享";
const string netWorkUser = "Administrator";
const string netWorkPwd = "admin123";
state = WNetHelper.WNetAddConnection(netWorkPath, new NetworkCredential(netWorkUser, netWorkPwd), "Z:");

 

命令行代码调用方式：

WNetHelper.ExecCommand("NET USE * /DELETE /Y", 0);
