How to remove special characters from file Metadata c#

问题

I am trying to find solution to this from last 2 hours, I have searched a lot on this but didn't found any solution(may be I am searching with wrong keywords), but the problem is I want remove file properties which contain special characters. Please check attached image for what I want to say.

I am using ASP.NET FileUpload control and C# as programming language. I want to make sure that any file uploaded does not contain any special characters in its properties.

Please help.

Thanks.

Have you tried looping through Image.PropertyItems?

You can modify the image to remove unwanted details via GetPropertyItem() and SetPropertyItem()
