System.drawing namespace not found under console application

问题

I selected console application as my C# project. But the imports that seemed to work under windows form project doesnt seem to work here. It says that the drawing namespace does not exist.

using System.Drawing;
using System.Drawing.Imaging;

My problem is that i need to have the bitmap class. I am trying to make a command line app that does bitmap manipulations to a image. That's why i didn't chose my project to be a windows form's one.

回答1:

Right click on properties of Console Application.
Check Target framework
If it is .Net framework 4.0 Client Profile then change it to .Net Framework 4.0

It works now

You need to add a reference to System.Drawing.dll.

As mentioned in the comments below this can be done as follows: In your Solution Explorer (Where all the files are shown with your project), right click the "References" folder and find System.Drawing on the .NET Tab.

If you are using Visual Studio 2010 or plus then check the target framework that is it .Net Framework 4.0 or .Net Framework 4.0 Client Profile. then change is to .Net Framework 4.0.

You need to add reference this .dll file (System.Drawing.dll) to perform drawing operations.

If it is OK then follow these steps to add reference to System.Drawing.dll

In Solution Explorer, right-click on the project node and click Add Reference.
In the Add Reference dialog box, select the tab indicating the type of component you want to reference.
Select the System.Drawing.dll to reference, then click OK.
