是否可以在C＃中创建有状态的Web服务？
我现在有这样的事情：
public class Service1 : System.Web.Services.WebService
{
[WebMethod]
public string Method1()
{
SomeObj so = SomeClass.GetSomeObj(); //this executes very long time, 50s and more
return so.Method1(); //this exetus in a moment
}
[WebMethod]
public string Method2()
{
SomeObj so = SomeClass.GetSomeObj(); //this executes very long time, 50s and more
return so.Method2(); //this exetus in a moment
}
...
}
SomeObj so
so
so
[WebMethod]
public List<ProcInfo> GetProcessList(string domain, string machineName)
{
string userName = "...";
string password = "...";
TaskManager tm = new TaskManager(userName, password, domain, machineName);
return tm.GetRunningProcesses();
}
[WebMethod]
public bool KillProcess(string domain, string machineName, string processName)
{
string userName = "...";
string password = "...";
(new TaskManager(userName, password, domain, machineName);).KillProcess(processName);
}
没有找到相关结果

很缴
[WebMethod] public string Method1() { SomeObj so = TryGetFromCacheOrStore<SomeObj>(() => SomeClass.GetSomeObj(), "so"); return so.Method1(); //this exetus in a moment } [WebMethod] public string Method2() { SomeObj so = TryGetFromCacheOrStore<SomeObj>(() => SomeClass.GetSomeObj(), "so"); return so.Method2(); //this exetus in a moment } private T TryGetFromCacheOrStore<T>(Func<T> action, string id) { var cache = Context.Cache; T result = (T)cache[id]; if (result == null) { result = action(); cache[id] = result; } return result; }哩翔购
//this executes very long time, 50s and more, but only once. private SomeObj SessionSomeObj { get { var ret = (SomeObj)Session["SomeObjStore"] ?? SomeClass.GetSomeObj(); SessionSomeObj = ret; return ret; } set { Session["SomeObjStore"] = value; } } [WebMethod(EnableSession = true)] public string Method1() { return SessionSomeObj.Method1(); //this exetus in a moment } [WebMethod(EnableSession = true)] public string Method2() { return SessionSomeObj.Method2(); //this exetus in a moment }方法。基本上，您调用Method1开始请求方法并在执行完成时获得回调。您可能需要调整Web服务客户端类的超时参数，以使其工作。 选项3 您可以使用SixPack库的缓存功能轻松完成此操作！ ;-) [评论后编辑]选项1中现在有两个静态字段，允许两个不同的实例，每个方法一个，如请求的那样。 [进一步说明后编辑]使用Session使调用成为有状态。 请参阅：http：//msdn.microsoft.com/en-us/library/aa480509.aspx 还添加了选项3。凸晴
更改为：并在您的类上添加以下属性：有关更多信息和示例，请参阅http://msdn.microsoft.com/en-us/library/system.servicemodel.sessionmode.aspx。
