从Windows 8.1进行文件访问

Question

I using C# for making an app. I want to access pictures form user system by using that code. Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)+ "//FolderName" . It was working fine on windows 10. But if we use that code in windows 8.1. It will generate "unauthorizedaccessexception" of path.Kindly help me to get ride of that problem.

Answer 1

Do you really use two forward slashes? I wonder that this worked at all. You should use backslashes. Also, always use System.IO.Path.Combine(...) to construct paths. Your code will also fail (with forward or backward slashes after the + ), if the part before the + already contains a backslash at the end. System.IO.Path.Combine(...) takes care of this.
