How do i get Filename, size, path etc into my Listview. If i just had a simple for each directly on the GetFiles, i could do something like

FileInfo f = new FileInfo(pdfFile);
long pdfSize = f.Length;
Response.Write(Path.GetFileName(pdfFile) + " - " + pdfSize.ToString() + "<br/>");

But how do i achive this in my ListView?

    You are selecting the paths to the files not the files itself. Hence you cannot get the FileInfo‘s properties what raises your exception “DataBinding: ‘System.String’ does not contain a property with the name ‘Name'”

    This should work:

    var currentPage = Directory.GetFiles(@"C:\mypath", "*.pdf").Skip((pageNum - 1) * pageSize).Take(pageSize).OrderBy(c => c).ToArray();
        .Skip((pageNum - 1) * pageSize)
        .Take(pageSize)
        .OrderBy(c => c)
        .Select(path => new System.IO.FileInfo(path)).ToArray();
