创建大量线程时的.Net内存泄漏

I have an application that creates lot of threads over time. I noticed that memory usage grows as it runs and eventually runs out of memory. But the same code doesn't leak memory on my coworker's environment. We both have same .net version. I was able to reproduce the issue with the following sample code which doesn't leak on my coworker's laptop but does on my laptop.public static void Main(string[] args){ Console.WriteLine("Version " + Environment.Version.ToString()); if (Environment.Is64BitProcess) Console.WriteLine("64"); else Console.WriteLine("32"); while(true) { Thread t = new Thread(() => { Thread.Sleep(1); }); t.IsBackground = true; t.Start(); Thread.Sleep(1); }}When I run the above, it prints the followingVersion 4.0.30319.1806332In Visual Studio 2012 the target framework for the project is .net framework 4.5.The project leaks memory with following configurationProject Properties -> Build Platform target: Any CPU Prefer 32-bit: checkedIf I unchecked Prefer 32-bit, it doesn't leak.Another configuration that leaks memory isProject Properties -> Build Platform target: x86 Prefer 32-bit: disabledThe resulting executable that leaks on my laptop doesn't leak on my coworker's laptop.I used CLR Profiler to find memory leaks but it doesn't show anything that's leaking. But I do see that working set in windows resource monitor increases by about 1 MB/sec.What is causing the memory usage to increase in 32-bit mode on my environment but not my coworker's? 解决方案 I've read all comments and afraid that my comment will be lost there, so try to answer.Use memory profiler designed for .NET applications, JetBrains dotMemory or ANTS or whatever but WinDBG or Task Manager or other native memory tools.You can compare how app behaves on your and your colleague's laptops using realtime chart of chosen profiler.I guess you will see that memory usage constantly increases on your laptop - just get a memory snapshot and see how many Thread objects are in memory, what objects take most of the memory and investigate why and by whom are they held in memory. 这篇关于创建大量线程时的.Net内存泄漏的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
