其中lpInfo的声明原型是一个LPVOID，如果设置Description属性的话指向的是一个结构： typedef struct _SERVICE_DESCRIPTION {
LPTSTR lpDescription;
} SERVICE_DESCRIPTION, *LPSERVICE_DESCRIPTION;
这个结构里面包含了一个字符指针，也就是说需要在函数调用时传递一个指向字符指针的指针，偷懒起见，ref System.String就足够了，无需再定义结构了，呵呵！ private static System.Boolean RegistService()
{
System.Boolean fRet = false;
System.IntPtr hServiceManager = IntPtr.Zero,hService = IntPtr.Zero;
System.String sServicePath = null,sDesc = null; sServicePath = Application.StartupPath + @"\sampleservice.exe";
hServiceManager = OpenSCManager(Environment.MachineName,null,SC_MANAGER_ALL_ACCESS);
if (hServiceManager != IntPtr.Zero)
{
hService = CreateService(hServiceManager,"sampleservice","Sample Service",SERVICE_ALL_ACCESS,

sServicePath,null,IntPtr.Zero,null,null,null);
if (hService != IntPtr.Zero)
{
sDesc = "This is a sample service.";
fRet = ChangeServiceConfig2(hService,SERVICE_CONFIG_DESCRIPTION,ref sDesc);

比较简单没什么可多说的看一个完整的例子： private static System.Boolean UnRegistService()
{
System.Boolean fRet = false;
System.IntPtr hServiceManager = IntPtr.Zero,hService = IntPtr.Zero; hServiceManager = OpenSCManager(Environment.MachineName,null,SC_MANAGER_ALL_ACCESS);
if (hServiceManager != IntPtr.Zero)
{
hService = OpenService(hServiceManager,"sampleservice",SERVICE_ALL_ACCESS);
if (hService != IntPtr.Zero)
{
fRet = DeleteService(hService);
CloseServiceHandle(hService);
hService = IntPtr.Zero;
}
CloseServiceHandle(hServiceManager);
hServiceManager = IntPtr.Zero;
}
return fRet;
}
