如何访问 Blazor 中的文件路径？

Question

I added a file to

wwwroot/assets

the file is called zip.csv

private const string fileName = "zip.csv";
private const string filePath = "/assets/";

In my method,

var strLines = File.ReadLines(filePath + fileName);

I am getting a crash (log below)

blazor.webassembly.js:1 System.IO.DirectoryNotFoundException: Could not find a part of the path "/assets/zip.csv".

I can navigate to http://localhost:5000/assets/zip.csv and download the file

Clientside Blazor is running in the same sandbox as javascript. To interact with the user's file system, use the HTML standard for accessing the file system, eg with this Blazor wrapper .

Maybe localStorage is sufficient ? Check this Blazor package to use it
