Remove readonly in Compact Framework

Question

What is the preferred way to remove the readonly attribute of a file in Compact Framework as we don't have a File::SetAttributes?

Answer 1

You could use the OpenNetCF Smart Device Framework, which has a FileHelper class that implements the SetAttributes function.

Or if you don't want to go that route, you could PInvoke the native SetFileAttributes method.

Answer 2

This also works:

FileInfo fileInfo = new FileInfo(path);
FileAttributes attributes = fileInfo.Attributes;

if ((attributes & FileAttributes.ReadOnly) == FileAttributes.ReadOnly)
{
    // set the attributes to nonreadonly
    fileInfo.Attributes &= ~FileAttributes.ReadOnly;
}
