Question

我使用的是Windows服务和Windows窗体。我一直在尝试向服务发送自定义命令，以便创建一个独立的存储文件。但是当我点击我的＆＃34; btnSubmit＆＃34;没有创建文件。出于某种原因，它似乎没有执行命令

我认为您需要添加ServieControllerPermission：

ServiceController sc = new ServiceController("YOURServiceName", Environment.MachineName);
ServiceControllerPermission scp = new ServiceControllerPermission(ServiceControllerPermissionAccess.Control,   Environment.MachineName, "YOURServiceName");//this will grant permission to access the Service
scp.Assert();
sc.Refresh();

sc.ExecuteCommand((int)YourMethods.methodX);

如何将自定义命令发送到服务c＃
