在Windows服务的安装类ProjectInstaller中加入以下方法：

复制代码 代码如下:

protected override void OnCommitted(System.Collections.IDictionary savedState)

{

base.OnCommitted(savedState);

//将服务更改为允许桌面交互模式

ConnectionOptions coOptions = new ConnectionOptions();

coOptions.Impersonation = ImpersonationLevel.Impersonate;

ManagementScope mgmtScope = new System.Management.ManagementScope(@"rootCIMV2", coOptions);

mgmtScope.Connect();

ManagementObject wmiService;

wmiService = new ManagementObject("Win32_Service.Name='这里是当前服务名'");

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

InParam["DesktopInteract"] = true;

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

}
