ASP.NET MVC: Can't figure out what VirtualPath is?
- by Ryan_Pitts
I have a View that displays a list of images and i am now trying to get it to display the images as thumbnails.  Well, i'm pretty sure i got most of it right using VirtualPath's from a custom ActionResult although i can't seem to figure out what it is making the VirtualPath url??  BTW, i'm using XML to store the data from the images instead of SQL.  Here is my code:
Code from my custom ActionResult:
public class ThumbnailResult : ActionResult
{
    public ThumbnailResult(string virtualPath)
    {
        this.VirtualPath = virtualPath;
    }
    public string VirtualPath { get; set; }
    public override void ExecuteResult(ControllerContext context)
    {
        context.HttpContext.Response.ContentType = "image/bmp";
        string fullFileName =
            context.HttpContext.Server.MapPath("~/Galleries/WhereConfusionMeetsConcrete/" + VirtualPath);
        using (System.Drawing.Image photoImg =
            System.Drawing.Image.FromFile(fullFileName))
        {
            using (System.Drawing.Image thumbPhoto =
                photoImg.GetThumbnailImage(100, 100, null, new System.IntPtr()))
            {
                using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
                {
                    thumbPhoto.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
                    context.HttpContext.Response.BinaryWrite(ms.ToArray());
                    context.HttpContext.Response.End();
                }
            }
        }
    }
}
Code for my Controller:
public ActionResult Thumbnail(string id)
{
    return new ThumbnailResult(id);
}
Code for my View:
<% foreach (var image in ViewData.Model) { %>
<a href="../Galleries/TestGallery1/<%= image.Path %>"><img src="../Galleries/TestGallery1/thumbnail/<%= image.Path %>" alt="<%= image.Caption %>" /></a>
<br /><br /><%= image.Caption %><br /><br /><br />
<% } %>
Any help would be greatly appreciated!!  Let me know of any questions you have as well. :)  Thanks!
