Here is a code snippet that someone else might find helpful. Also if anyone else knows a better way to do this please let me know.

/// Returns the size of the directory in bytes
public static long Size(System.IO.DirectoryInfo dirInfo)
{
  long total = 0;

  foreach(System.IO.FileInfo file in dirInfo.GetFiles())
    total += file.Length;
  
  foreach(System.IO.DirectoryInfo dir in dirInfo.GetDirectories())
    total += Size(dir);

  return total;
}

Using Embedded Images in ASP.Net V2

Thanks to Yves and Peter for the advise I utilized your advise to create a new version my embedded Image example. I did switch to an ashx file, I didn't even know about this file type until now. I'm no longer passing in the assembly as a parameter but I didn't want to put the assembly in the config file either, so I figured that I would just test for the image by the passed in name in all the assemblies loaded into that AppDomain. There shouldn't be to many right? But you do have to make sure that embedded image has a unique name, that shouldn't be to hard though because you can prefix it by your namespace.

<% @ webhandler language="C#" class="ImageHandler" %> 

public class ImageHandler : System.Web.IHttpHandler 
{ 
  public void ProcessRequest(System.Web.HttpContext context) 
  { 
    string image = string.Empty;
    System.IO.Stream stream = null;
      
    try
    {
      context.Response.Clear();

      // Get Image Name from request
      image = context.Request["img"].Replace("/", ".");   
  
      // Find image in loaded assemblies
      foreach(System.Reflection.Assembly asm in System.AppDomain.CurrentDomain.GetAssemblies())
      {
        stream = asm.GetManifestResourceStream(image);
        if(stream != null)
          break;
      }
      
      // Throw exception if image is not found
      if(stream == null)
        throw new System.Exception("Image not found in loaded assemblies");
            
      // Create an Image object from the stream
      System.Drawing.Image img = System.Drawing.Image.FromStream(stream);
      
      // Save the Image stream to the output stream
      img.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif);
    }
    catch(System.Exception ex)
    {
      context.Response.Write("Exception: <BR>image = " + image + "<BR>" +
        ex.Message + "<BR>" + ex.StackTrace.Replace("\n", "<BR>"));  
    }
    finally
    {     
      context.Response.End(); 
    }; 
  } 
   
  public bool IsReusable 
  { 
    get { return true; } 
  } 
}

So what do you guys think about revision 2?
