StreamReader access to the path is denied!

Question

Thursday, August 16, 2018 9:33 AM

Hi all,

I must use the code page 936, the StorageFile class can't support code page 936. The StreamReader class can only open the file under the current folder but can't open the file which is under "c:\Data\USERS\Public\ folder (Access to the path 'c:\Data\USERS\Public\readme.txt' is denied.), how to fix this?

  <Capabilities>
    <Capability Name="internetClientServer" />
    <Capability Name="privateNetworkClientServer" />
    <uap:Capability Name="musicLibrary" />
    <uap:Capability Name="picturesLibrary" />
    <uap:Capability Name="videosLibrary" />
    <uap:Capability Name="removableStorage" />
    <uap:Capability Name="enterpriseAuthentication" />
    <rescap:Capability Name="broadFileSystemAccess" />
  </Capabilities>

Best regards.

There must be set the APPX Folder Permissions before use the StreamReader API.

The code works fine now. I test this on the v10.0.17763.107.

Command> folderpermissions c:\data\users\public -e

APPX Folder Permissions
Setting APPX R/W Permissions on folder c:\data\users\public
Success - APPX R/W Permissions now set on folder c:\data\users\public

            EncodingProvider provider = CodePagesEncodingProvider.Instance;
            Encoding.RegisterProvider(provider);
            Encoding e = Encoding.GetEncoding(936);

            string filePath = @"TextFile1ansi.txt";
            StreamReader readFile = new StreamReader(filePath, e);//OK!
            string content = readFile.ReadLine();//OK!

            string filePath4 = @"c:\Data\USERS\Public\readme.txt";
            StreamReader readFile2 = new StreamReader(filePath4,e);//Access denied!
            string content2 = readFile2.ReadLine();

Hello moyanming,

I have tested this issue on winodws iot core. The app also show the same error. I also checked this issue on uwp desktop, but it works fine on desktop.
