  1. First assign the file name to a string variable and then use that variable to open the file

    Something like that:

    string nombreArvhivo = @"XXXXX"
string[] lineas = System.IO.File.ReadAllLines(nombreArchivo);
//nombreArchivo tiene el nombre del archivo leído.

    If you want to get only the file name you can do the following:

    string nombreArchivo = System.IO.Path.GetFileName(@"XXXXX");

    This way you get just the file name, without the full path.

  3. To obtain the name of a file knowing the path, you can do it with Path.GetFileName(string)if you are interested in keeping the extension, or Path.GetFileNameWithoutExtension(string)in case you prefer the file name without it.

    Therefore, it would be enough to store the path in a variable and make use of one of these methods.

    string path = "@XXXX";
string[] lineas = System.IO.File.ReadAllLines(path);
string nombreArchivoConExtension = System.IO.Path.GetFileName(path);
string nombreArchivoSinExtension = System.IO.Path.GetFileNameWithoutExtension(path);

    Assuming it path was worthC:\Info\CATÁLOGOS\ANILAG P1T M12.pdf

    the variable nombreArchivoConExtensionwill be equal to ANILAG P1T M12.pdfandnombreArchivoSinExtension ANILAG P1T M12
