如何从 Visual Studio 解决方案/项目中读取文件？

Question

 FileInfo template = new  FileInfo(@"C:\Users\bryan\Desktop\ReportTemplate.xlsx");
 template.IsReadOnly = false;

This is fine for test, but I have the ReportTemplate.xlsx inside of my project solution. How can I use that file instead of a local one on my desktop? How do I reference the file inside the solution?

Answer 1

You want to use Server.MapPath();

Make sure the file you want has been added to the project: File->Add Existing

FileInfo template = new  FileInfo(Server.MapPath("~/Directory/ReportTemplate.xlsx");
template.IsReadOnly = false;

The ~ represents "root" of the project.

I think this will only work with ASP.NET.

Answer 2

It depends where the file in the solution is located. The home folder is \bin\debug in the project folder which you build. If you want to reference the file which is in the root of you project folder use "..\..\yourfilename.xlsx"

Answer 3

File Properties->Copy to Output Directory

Then you can access it with "ReportTemplate.xlsx"
