为什么骑手在 /bin/debug/net5.0 中查找文件

Question

我尝试使用 txt 文件，但我的 ide 找不到它，这是堆栈跟踪

Unhandled exception. System.IO.FileNotFoundException: Could not find file 'C:\Users\Tudor\RiderProjects\WinterInternship2022-Backend-main\SantaClauseConsoleApp\SantaClauseConsoleApp\bi
n\Debug\net5.0\letter-template.txt'.

   at SantaClauseConsoleApp.Program.Main(String[] args) in C:\Users\Tudor\RiderProjects\WinterInternship2022-Backend-main\SantaClauseConsoleApp\SantaClauseConsoleApp\Program.cs:line 12

这是文件的调用

StreamReader reader = new StreamReader("letter-template.txt");

我也试过绝对路径没有问题问题是搜索window虽然我不知道如何设置它。

因为（看起来）你是运行在调试模式下编译的（所以输出在 bin\Debug\net5.0\ 中）并且 "letter-template.txt" 将被搜索为相对路径并考虑输出文件夹作为根。

如果将 "letter-template.txt" 添加到项目中，您可以将其自动复制到输出目录 - 在解决方案资源管理器中右键单击它，然后将“复制到输出目录”选项设置为“如果更新则复制” ".
