Problem uploading with MS Edge

Question

User-1209166642 posted

First please see this post: https://forums.asp.net/t/2166962.aspx

The code in that post works perfect in Firefox and Chrome.  However it does not in Edge.

For example, if the image is located at C:\Users\jimwin7a\Pictures\ann.jpg

Firefox works and just ann.jpg is stored for file name, but Edge stores this for file name C:\Users\jimwin7a\Pictures\ann.jpg

Actually something like ann37.jpg (see the code that works in other post).  And image isn't uploaded to server, it put in same folder you get the file from.

Why in the World wouldn't Edge handle proper file uploads?

Again code here https://forums.asp.net/t/2166962.aspx works perfect in the other two mentioned browsers.

So any help would be nice.

The application should name the file not the client.

https://docs.microsoft.com/en-us/aspnet/core/mvc/models/file-uploads?view=aspnetcore-3.1

Use a safe file name determined by the app. Don't use a file name provided by the user or the untrusted file name of the uploaded file.† HTML encode the untrusted file name when displaying it. For example, logging the file name or displaying in UI (Razor automatically HTML encodes output).

I was able to fix by adding this:

added           string Result = Path.GetFileName(filename);  //MS example I found
changed to      Array getparts = StrHelper.SplitString(Result);

//  Now works in Edge and FF and Chrome.

I hope it helps someone.
