.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。
