C# Filepath Recasing

Question

I\'m trying to write a static member function in C# or find one in the .NET Framework that will re-case a file path to what the filesystem specifies.

Example:

<

Answer 1

This is a pretty simple implementation that assumes that the file and directories all exist and are accessible:

static string GetProperDirectoryCapitalization(DirectoryInfo dirInfo)
{
    DirectoryInfo parentDirInfo = dirInfo.Parent;
    if (null == parentDirInfo)
        return dirInfo.Name;
    return Path.Combine(GetProperDirectoryCapitalization(parentDirInfo),
                        parentDirInfo.GetDirectories(dirInfo.Name)[0].Name);
}

static string GetProperFilePathCapitalization(string filename)
{
    FileInfo fileInfo = new FileInfo(filename);
    DirectoryInfo dirInfo = fileInfo.Directory;
    return Path.Combine(GetProperDirectoryCapitalization(dirInfo),
                        dirInfo.GetFiles(fileInfo.Name)[0].Name);
}

There is a bug with this, though: Relative paths are converted to absolute paths. Your original code above did the same, so I'm assuming that you do want this behavior.
