Question

我是C＃和Visual Studio的初学者。我已经构建了一个Silverlight应用程序，以便在播放器中获取自定义参数，以便在浏览器中播放视频。

下面给出了从浏览器运行应用程序的代码：

        // When running outside the browser, retrieve initParams from isolated storage.
        if (Application.Current.IsRunningOutOfBrowser)
        {
            using (IsolatedStorageFile file =
                IsolatedStorageFile.GetUserStoreForApplication())

            using (var stream = new IsolatedStorageFileStream(
                "initParams.txt", System.IO.FileMode.Open, System.IO.FileAccess.Read, file))
            {
                // The serializer requires a reference to System.Runtime.Serialization.dll.
                DataContractSerializer serializer =
                    new DataContractSerializer(typeof(Dictionary<String, String>));
                initParams = (Dictionary<String, String>)serializer.ReadObject(stream);
            }
        }
        // Otherwise, save initParams to isolated storage.
        else
        {
            initParams = e.InitParams;

            using (IsolatedStorageFile file =
                IsolatedStorageFile.GetUserStoreForApplication())
            using (IsolatedStorageFileStream stream = new IsolatedStorageFileStream(
                "initParams.txt", System.IO.FileMode.Create, file))
            {
                DataContractSerializer serializer =
                    new DataContractSerializer(typeof(Dictionary<string, string>));
                serializer.WriteObject(stream, initParams);
            }
        }

我收到错误，不允许操作。代码中的IsolatedStorage异常

            using (IsolatedStorageFile file =
                IsolatedStorageFile.GetUserStoreForApplication())

            using (var stream = new IsolatedStorageFileStream(
                "initParams.txt", System.IO.FileMode.Open, System.IO.FileAccess.Read, file))

Visual Studio中的错误消息是

System.IO.IsolatedStorage.IsolatedStorageException：不是操作在IsolatedStorageFileStream上允许。在 System.IO.IsolatedStorage.IsolatedStorageFileStream..ctor（String path， FileMode模式，FileAccess访问，FileShare共享，Int32 bufferSize， IsolatedStorageFile isf）at System.IO.IsolatedStorage.IsolatedStorageFileStream..ctor（String path， FileMode模式，FileAccess访问，IsolatedStorageFile isf）at testplayer.App.LoadInitParams（StartupEventArgs e）at testplayer.App.Application_Startup（Object sender，StartupEventArgs e）在MS.Internal.CoreInvokeHandler.InvokeEventHandler（UInt32 typeIndex，委托handlerDelegate，Object sender，Object args）at MS.Internal.JoltHelper.FireEvent（IntPtr unmanagedObj，IntPtr unmanagedObjArgs，Int32 argsTypeIndex，Int32 actualArgsTypeIndex， String eventName，UInt32 flags）

任何人都可以帮我解决这个问题吗？

提前致谢

IsolatedStorageFileStream上不允许操作。 IsolatedStorage异常
