.net解决iis无法访问磁盘映射

前段时间用到iis服务器读写磁盘映射文件，发现权限问题导致无法找到磁盘。

这里只需要在iis用代码映射下就可以访问了。

//使用系统网关API

[DllImport("mpr.dll", EntryPoint ="WNetAddConnection2")]

        privatestaticexternuintWNetAddConnection2(NetResourcelpNetResource,string lpPassword, stringlpUsername,uint dwFlags);

//定义NetResource

[StructLayout(LayoutKind.Sequential)]

        publicclassNetResource

        {

            publicintdwScope;

 

            publicintdwType;

 

            publicintdwDisplayType;

 

            publicintdwUsage;

 

            publicstringlpLocalName;

 

            publicstringlpRemoteName;

 

            publicstringlpComment;

 

            publicstringlpProvider;

        }

//检查磁盘是否可以查到，无法查到进行磁盘映射

string letter = "Z:";

               if (!Directory.Exists(letter))

               {

remoteName="映射服务器及端口号";

NetResourcenetResource =new NetResource();

 

           netResource.dwScope = 2;

           netResource.dwType = 1;

            netResource.dwDisplayType = 3;

           netResource.dwUsage = 1;

           netResource.lpLocalName = letter;

           netResource.lpRemoteName = remoteName.TrimEnd('\\');

                   WNetAddConnection2(netResource, "密码","账号", 0);

               }

映射之后就有权限进行访问了。
