Strange namespace problem

Question

I am trying to use the System.Drawing.Color namespace. I cannot define it at the top of the class:

However, I can reference it inside the class. That is, I can use this line of code, and it works:

txtBox.BackColor = System.Drawing.Color.LightPink; 

... but I would just like to do this:

 txtBox.BackColor = Color.LightPink; 

If this is a question of missing a / dll link, why can I link to System.Drawing.Color in my code?

Answer 1

This is because it is not a namespace. System.Drawing is the namespace, and Color is the structure ( struct ).

EDIT: Also, I would suggest using a product like ReSharper , which can fix such things almost automatically. ReSharper Rules!

Answer 2

The reasons why I can think about why System.Drawing can be filtered in the usings drop-down list:

• it's already in use (- nah, maybe not, but anyway)
• You are in an ASP.NET service:

A warning. Classes in the System.Drawing namespace are not supported for use in a Windows service or ASP.NET. Attempting to use these classes from one of these application types can cause unforeseen problems, such as degraded service performance and runtime exceptions.

Answer 3

System.Drawing.Color is a structure. Namespace - System.Drawing

Answer 4

Have you added a link to: System.Drawing in your References project?

Answer 5

You must add it to your links - somehow it is missing.

then you should declare using System.Drawing; at the top of your C # code, after which you can call Color.LightPink;
