How to call a long method in a new thread to keep the UI running in C#
提问by 0xFF
I have WPF application with a combobox filled with Users, a grid showing some data for the selected User and a button that calls DoTimeSheetReport().
我有一个 WPF 应用程序，其中包含一个填充有用户的组合框、一个显示所选用户的一些数据的网格和一个调用 DoTimeSheetReport() 的按钮。
DoTimeSheetReport() does some work and then opens a new window with a SSRS report. Everything works fine but the method takes a long time to complete, mostly because of the report, which means my UI becomes unresponsive. I tried a couple of ways to start a new thread/task but all of them are blocking the UI's thread. I'm probably doing something wrong but I have no idea.
DoTimeSheetReport() 做了一些工作，然后打开一个带有 SSRS 报告的新窗口。一切正常，但该方法需要很长时间才能完成，主要是因为报告，这意味着我的 UI 变得无响应。我尝试了几种方法来启动一个新的线程/任务，但所有这些都阻塞了 UI 的线程。我可能做错了什么，但我不知道。
What's the best way to call a long method in order to not block the UI?
为了不阻塞 UI，调用长方法的最佳方法是什么？

I changed my code to isolate the time-consuming part.
我更改了代码以隔离耗时的部分。
reportViewer.SetPageSettings(reportConfiguration.PageSettings);
Using a backgroundWorker on this part did it. Thank you for your help.
在这部分使用 backgroundWorker 做到了。感谢您的帮助。

using System.Threading;
new Thread(() =>
{
Thread.CurrentThread.IsBackground = true;
/* run your code here */
Console.WriteLine("Hello, world");
}).Start();

In short:what you need to do is to look at how to use async calls.
简而言之：你需要做的是看看如何使用异步调用。
