C# Newby Image Question

[Fred Nelson]

Hi:

I have programmed in VB.NET for about a year and I'm in the process of
learing C#. I'm really stuck on this question - and I know it's a "newby"
question:

In VB.NET I have several routines that upload and process images. I can't
get past "square one" with images in C#:

This statement:

Image myImage;

results in an "ambigous reference" error.

I've searched MSDN and Google and I'm confused - I've tried
System.Drawing. Image and haven't had any luck!!!

I must have a namespace issue or something - any help would be GREATLY
apprecaited!

Thanks,

Fred

What type of application? When I try "Image myImage;" in a windows forms
app, I get no compiler error, but when I try to create an actual object with
"Image myImage = new Image();", I get "Cannot create an instance of the
abstract class System.Drawing. Image.". In this context, I'd need to
instantiate a subclass of Image, either Bitmap or Metafile.
I got your error message in a test web app, because there is an Image class
in each of the following places:
System.Drawing. Image myImage;

System.Web.UI.W ebControls.Imag e myImage2;

Therefore, you have to specify which you want.

My guess is that you've got at least two of:

using System.Drawing;
using System.Web.UI.M obileControls;
using System.Web.UI.W ebControls;

at the top of your class. You should almost certainly only be using one
of those namespaces.

Can you copy/paste your using directives? So we can see, which
namespaces are you using...

Have you created your own class called Image?

Aside from Jon Skeet's advice if you want to have several of the namespaces
included all you need to do is to fully qualify the declaration of myImage
such as:

System.Drawing. Image myImage;

Peter:

Thanks for your help! The app I'm working on is a C# web application.

It appears that by removing the reference to System.Web.UI.W ebControls I
have solved the problem as that namespace and System.Drawing both have Image
defined.

Thanks very much!

Saso:

I was using the default directives inserted in a new web page. The conflict
was with System.Drawing and System.Web.UI.W ebControls.
