Uploading images

Posted on 2008-10-06
Last Modified: 2013-12-25
I am a beginner and this is my very first website project.

I am populating an array using Server.MapPath. On my local machine it is trying to read from
C:\Documents and Settings\\My Documents\Visual Studio 2008\Projects folder. I thought the Server.MapPath would read from C:\inetpub\wwwroot.
The array I am creating is getting all images from a folder. I want to allow the user to upload images to this folder. When I save the images from the user the images are being stored in C:\inetpub\wwwroot on my local machine.

here is my save path
        string savePath = @"c:\inetpub\wwwroot\SlideShow\Files\" + folderName;

this is how I retrieve the images
    protected void Page_Load(object sender, EventArgs e)
        //create a string to hold the images for the banner
        StringBuilder imageArray = new StringBuilder();
        imageArray = GetImageArray(ResolveClientUrl(folderName));
        //register array so it can be referenced in javascript
        ClientScriptManager csm = Page.ClientScript;
        csm.RegisterArrayDeclaration("Pictures", imageArray.ToString());

    protected StringBuilder GetImageArray(string folderName)
        string Path;
        DirectoryInfo Folder;

        FileInfo[] Images;
        StringBuilder ImageArray = new StringBuilder();

        Path = Server.MapPath(folderName);
        Folder = new DirectoryInfo(Path);
        Images = Folder.GetFiles();
        // Looping through all files in the folder and generating
        // a JavaScript array declaration.
        foreach (FileInfo Image in Images)
            if (Image.Extension.StartsWith(".jpg") || Image.Extension.StartsWith(".JPG"))
                ImageArray.AppendFormat("'{0}/{1}',", folderName, Image.Name);

        if (ImageArray.Length > 0)
            // Removing the unwanted last comma.
            ImageArray.Remove(ImageArray.Length - 1, 1);

        return ImageArray;

Server.MapPath will map to the projects folder when running in debug because this is where it is executing, however when deployed to the iis folder it shoud map correctly...

Would I be better off saving the images with something similar to server.mappath rather than writing out  @"c:\inetpub\wwwroot\SlideShow\Files\"?

Yes, you should never hard code paths, if you need to use the full path like that you can use the web.config file to store configuration...

the best way to code is using \ and ..\ instead of hardcoding the C:\......

>>>On my local machine it is trying to read from
C:\Documents and Settings\\My Documents\Visual Studio 2008\Projects folder
Is this the folder that you have all your ASPX files in?
>>>string savePath = @"c:\inetpub\wwwroot\SlideShow\Files\" + folderName;
Is "SlideShow" the virtual directory of your application?

I did deploy it and checked it and it worked. I was just kinda fuzzy on why Server.MapPath was reading files from the visualstudio/projects folder on my local machine when Server.MapPath was storing images in c:\inetpub\wwwroot\SlideShow\.............  on my local machine. But it is working on the server. I am learning new things and discovering new things each day I work on this. Thanks guys..gals?.....
