如何在windows服务中打开文件

//windows服务默认是不支持与桌面进行交互的，所以就无法打开硬盘上的文件，比如播放音乐等。//需要在serviceProcessInstaller1的Committed事件中添加如下代码：

ConnectionOptions myConOptions = new ConnectionOptions();
myConOptions.Impersonation = ImpersonationLevel.Impersonate;
ManagementScope mgmtScope = new System.Management.ManagementScope(@"root\CIMV2", myConOptions);

mgmtScope.Connect();
ManagementObject wmiService = new ManagementObject("Win32_Service.Name='" + serviceInstaller1.ServiceName + "'");

ManagementBaseObject InParam = wmiService.GetMethodParameters("Change");

InParam["DesktopInteract"] = true;

ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", InParam, null);

//在你需要打开文件的代码处添加如下代码打开文件
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "文件所在目录";
process.StartInfo.WorkingDirectory = "文件根目录";
process.Start();
