C#程序保存dump文件

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

程序异常崩溃前使用此类为进程创建DUMP文件，之后可以使用WinDbg等工具进行分析。

}


提示

对于Windows Form程序，可以利用AppDomain的UnhandledException事件。以下示例：

namespace WindowsFormsApplication1
{
    static class Program
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            AppDomain.CurrentDomain.UnhandledException +=new UnhandledExceptionEventHandler((obj,args)=> MiniDump.TryDump("error.dmp"));

            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}

windbg 这个工具可以手动的来抓dump文件，如果你想你的程序智能一些，当遇到你开发的程序crash时，你想程序自己抓到dump文件，然后你去分析就可以。最近我刚好遇到这样一个事情，所以找了找，借助网络和论坛的朋友，才完成了这样一个事情。MiniDumpWriteDump 这个win32 api 可以完成这样一个事情。因为现在使用的是c#，所以封装了一下，本人对托管代码调用那些win api也不是很了解。所以借助了一些朋友来帮忙。

我就 直接贴代码出来吧，运行一下 就知道了，但到目前位置 我还么有对这个测试程序抓到的dump进行过分析。以后在分析吧，现在的机器上没有环境。
