Question

如何使用c＃以编程方式为任意Windows服务设置“登录”凭据（wmi / interop很好）？

注意，我的程序是以管理员身份运行的，我需要将更改保留（对于所有后续服务重新启动）

理想情况下，该方法具有以下信号：

void SetWindowsServiceCreds(string serviceName, string username, string password) 
{
   // TODO write me
}

[DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Auto)]
[return: MarshalAs(UnmanagedType.Bool)]

这也有效：

      void SetWindowsServiceCreds(string serviceName, string username, string password)
        {
            string objPath = string.Format("Win32_Service.Name='{0}'", serviceName);
            using (ManagementObject service = new ManagementObject(new ManagementPath(objPath)))
            {
                object[] wmiParams = new object[10];

                wmiParams[6] = username;
                wmiParams[7] = password;
                service.InvokeMethod("Change", wmiParams);
            }

        }
