Accessing a file held within a project folder in Visual Studio

Question

Within Visual Studio I have got a file which I would like to get access to in one of my classes. This project is going onto source control so I'd like to use a relative path which points to where it is located inside the project. I've tried the following which always returns a DirectoryNotFoundException :

filePPT = new PowerPointFile("~/IO/ExportTools/Template.pptx");

And

filePPT = new PowerPointFile("~\\IO\\ExportTools\\Template.pptx");

The location of my file is in the following structure:

How can I access the file within Visual Studio using a relative path?

Answer 1

将文件的“ CopyToOutputDir”属性设置为“复制，如果较新”，以便将其复制到输出文件夹中，然后创建相对于应用程序启动路径的路径

filePPT = new PowerPointFile(Path.Combine(Application.StartupPath, "IO/ExportTools/Template.pptx"));
