C#多线程形式的AccessViolationException [英] AccessViolationException in C# multithreaded form

问题描述

首先这是我的第一个 C# 项目.我已经在这个项目上工作了大约 6 个月.

First off this is my first C# project. I have been working on this project for about 6 months.

我们有一个 winforms 程序，它包含一个日志记录 GUI.为了让程序的其余部分保持响应，我想在一个单独的线程上创建日志 gui，因为当有很多事情发生时它可能会非常密集.

We have a winforms program and it contains a logging GUI. In order to keep the rest of the program responsive I wanted to create the logging gui on a separate thread since it can be quite intensive when lots of stuff is going on.

这就是我尝试在新的 GUI 线程上打开表单的方式.一般来说，它可以工作并保持主 gui 响应.然而，当它被激活时，我们现在随机得到一个 AccessViolationException (http://pastebin.com/7tLtBSei)不知所措.

This is how I attempted to open the the form on a new GUI thread. In general it works and keeps the main gui responsive. However we now randomly get a AccessViolationException (http://pastebin.com/7tLtBSei) when this is activated and I am at a loss.

var thread = new Thread(() =>
{
    loggingForm = new LoggingForm(Logger.path);
    Application.Run(loggingForm);
});
thread.Name = "LoggingFormGUIThread";
thread.Start();

日志 GUI 只是批量读取日志文件并将其附加到 RichTextBox.它不涉及任何托管代码.

The logging GUI just batch reads the log file and appends it to a RichTextBox. It doesn't touch any managed code.

推荐答案

需要将线程的单元状态设置为STA.

You need to set the apartment state of the thread to STA.

thread.SetApartmentState(ApartmentState.STA);
thread.Name = "LoggingFormGUIThread";
thread.Start();

这是许多用户界面组件(例如 RichTextBox)正常运行所必需的.

This is required for many user interface components (such as RichTextBox) to function correctly.
