通过快捷方式打开VS Code是编译不了的,需要对tasks.json修改(Tasks: Configure default build task)
先创建tasks.json

复制这段配置到tasks.json,记得修改VsDevCmd.bat的路径

{   "version": "2.0.0",   "windows": {     "options": {       "shell": {         "executable": "cmd.exe",         "args": [           "/C",           // The path to VsDevCmd.bat depends on the version of Visual Studio you have installed.           "\"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/Common7/Tools/VsDevCmd.bat\"",           "&&"         ]       }     }   },   "tasks": [     {       "type": "shell",       "label": "cl.exe build active file",       "command": "cl.exe",       "args": [         "/Zi",         "/EHsc",         "/Fe:",         "${fileDirname}\\${fileBasenameNoExtension}.exe",         "${file}"       ],       "problemMatcher": ["$msCompile"],       "group": {         "kind": "build",         "isDefault": true       }     }   ] } 

不能通过点击运行来运行,需要当作任务运行
