unzipping files

[michaeldebruin]

Hello all,

I am trying to create an installer for my program. Which can unzip the folder in which it is downloaded. The Download part works fine. But I am repeatedly getting the error that the my file path is invalid during the unzip proces.

This is where I am trying to get the unzip method:

string dirpath = sfd.FileName;
                DirectoryInfo di = new DirectoryInfo(dirpath);

                foreach(FileInfo fi in di.GetFiles("MyProgram.zip"))
                {
                    Decompress(fi);
                }

This is the unzip proces itself:

            using (FileStream inFile = fi.OpenRead())
            {
                string curFile = fi.FullName;
                string origName = curFile.Remove(curFile.Length - fi.Extension.Length);

                using (FileStream outFile = File.Create(origName))
                {
                    using (GZipStream Decompress = new GZipStream(inFile,CompressionMode.Decompress))
                    {
                        Decompress.CopyTo(outFile);
                    }
                }
            }

Can you add the actual error message please?

I haven't changed anything, but now it says "The Directoryname is invalid". This error appears when the download is ready and I am trying to upzip the file. Visual Studio doesn't give any errors while building the program.

Do you know on which line it fails?

if not, change your code to this:

    string dirpath = sfd.FileName;
    System.Console.WriteLine("DirPath = " + dirpath);
    DirectoryInfo di = new DirectoryInfo(dirpath);
    System.Console.WriteLine("DirInfo Created");
    foreach(FileInfo fi in di.GetFiles("MyProgram.zip"))
    {
        System.Console.WriteLine("Decompressing " + fi.Name);
        Decompress(fi);
        System.Console.WriteLine("Decompress Complete")
    }

And then post the console window in code tags.
