UdpClient.ReceiveAsync correct early termination

荒凉一梦 提交于 2020-01-10 02:14:03
问题 Good day. I work with UdpClient and have wrapper upon it. For reading I have asynchronous method: private async Task<byte[]> Receive(UdpClient client, CancellationToken breakToken) { // Выход из async, если произошёл CancellationRequest breakToken.ThrowIfCancellationRequested(); UdpReceiveResult result; try { result = await client.ReceiveAsync().WithCancellation(breakToken); } catch(OperationCanceledException) { // Штатная ситуация ручной остановки Task-а } return result.Buffer; } Where

ObjectDisposeException when trying to send thru a reopened socket

喜你入骨 提交于 2020-01-06 09:58:59
问题 I'm using Socket (Socket A = new Socket...) to send/receive. when something bed happens (disconnection), I'm trying to close/dispose old object, and then instancing a new socket (A = new Socket...) (same host/port) The connect() phase checks out fine, the remote host sees the connection. Upon trying to send the very first byte, I immediately get: System.ObjectDisposedException: Cannot access a disposed object. Object name: 'System.Net.Sockets.Socket'. at System.Net.Sockets.Socket.Send(Byte[]

ObjectDisposedException when .Show()'ing a form that shouldn't be disposed

一曲冷凌霜 提交于 2020-01-02 07:19:29
问题 ive checked out some of the other questions and obviously the best solution is to prevent the behavior that causes this issue in the first place, but the problem is very intermittent, and very un-reproduceable. I basically have a main form, with sub forms. The sub forms are shown from menus and/or buttons from the main form like so: private void myToolStripMenuItem_Click(object sender, EventArgs e) { try { xDataForm.Show(); xDataForm.Activate(); } catch (ObjectDisposedException) { MessageBox

System.ObjectDisposedException Error on C# v4.0

拟墨画扇 提交于 2019-12-24 00:36:04
问题 I implemented this code: C# Processing Fixed Width Files But since my work PC runs Windows XP I had to save the program using C# v4.0. Unfortunately the following code: static string filePath = ""; public Main() { InitializeComponent(); } private void buttonLoadFile_Click(object sender, EventArgs e) { DialogResult openFile = openFileDialog.ShowDialog(); if (openFile == DialogResult.OK) { filePath = openFileDialog.FileName; } } private void buttonProcessFile_Click(object sender, EventArgs e) {

Why is my FileStream object being disposed of when I'm “using” a BinaryReader object?

一个人想着一个人 提交于 2019-12-23 14:36:08
问题 Consider the following function: private int GetSomethingFromFile(FileStream fs) { using (BinaryReader br = new BinaryReader(fs)) { fs.Seek(0, SeekOrigin.Begin); return br.ReadInt32(); } } A FileStream object is passed in as a parameter and a BinaryReader is declared with a using statement. When I try to use that FileStream object, after calling this function, it throws a System.ObjectDisposedException. Why is that FileStream object being disposed of along with the BinaryReader object? 回答1:

SlidingMenuSharp System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Android.Widget.Scroller'

风格不统一 提交于 2019-12-23 05:49:08
问题 We have a Xamarin.Android 7 app. We are getting the following exception which causes the app to crash. It says something about Android.Widget.Scroller, but we are not using this component explicitly in our app anywhere. We are using ScrollView and GridView in xaml files though. One solution which we came across was to move back to Xamarin.Android 6, but that is not a feasible solution due to app requirements. One more solution we came across was to use ListViewCachingStrategy, but couldn't

Program crash with System.ObjectDisposedException

我与影子孤独终老i 提交于 2019-12-22 04:22:08
问题 I'm having a weird problem with my program. I'm developing a windows form application. When I debug it through Visual Studio (F5) it works perfectly correctly, but when I run its executable it crashes and gives me "An unhandled exception of type 'System.ObjectDisposedException' occurred in mscorlib.dll". I tried to put a top level (on my outermost function) try/catch for catching this exception, but still the program crashes. What am I missing here? I didn't upload the code because I had to

How can I resolve inexplicable ObjectDisposedExceptions in my C# / MVVM application?

和自甴很熟 提交于 2019-12-22 00:34:54
问题 I've written my first MVVM application. When I close the application, I often get a crash cause by an ObjectDisposedException. The crash appears as the application dies, just after the app window disappears. Getting a stacktrace was difficult (see my other question), but finally I did, and found that my stacktrace is entirely contained within C# libraries (kernel32!BaseThreadStart, mscorwks!Thread, mscorwks!WKS, etc). Furthermore, this crash is inconsistent. After my last checkout and rebuild

How do you dispose a tracelistener properly?

泄露秘密 提交于 2019-12-20 04:57:16
问题 I've actually written a tracelistener component that logs to a networkstream. The code for that is here: using Newtonsoft.Json.Linq; using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Net.Sockets; using System.Text; using System.Threading.Tasks; namespace System.Diagnostics { public class NetworkStreamWriterTraceListener : DelimitedListTraceListener { NetworkStream _stream; StreamWriter _writer; StreamReader _reader; TcpClient client; bool
