一、生成Dump文件在Windows上生成Dump文件（内存转储文件）主要有以下几种方法，适用于不同场景。1、任务管理器生成Dump文件1）打开任务管理器（Ctrl+Shift+Esc）2）在“详细信息”选项卡中找到目标进程3）右键点击进程 → “创建转储文件”4）文件默认保存在：%temp%\进程名.dmp2、使用Procdump工具（微软官方推荐）下载安装从微软官网下载Procdump：https://learn.microsoft.com/en-us/sysinternals/downloads/procdump常用命令示例cmd# 1. 立即生成进程的完整Dump procdump -ma PID 或 procdump -ma 进程名 # 2. 当CPU使用率超过阈值时生成Dump procdump -ma -c 90 -s 10 进程名 # 3. 监控异常并生成Dump procdump -ma -e 1 进程名 # 4. 连续生成多个Dump procdump -ma -n 5 进程名 # 5. 带时间戳的文件名 procdump -ma -s 10 -n 3 -d 进程名3、C/C++ 代码生成Dump使用MiniDumpWriteDump API生成dump文件。minidump.h#ifndef MINIDUMP_H #define MINIDUMP_H #include QString #include windows.h #include dbghelp.h #pragma comment(lib, "dbghelp.lib") class MiniDumpGenerator { public: static void initialize();
