Problems with referencing assemblies and using namespaces

okacha

What is the difference between using assemblies and referencing assemblies under VS Project Manager? ? I found that using namespaces still can't use the namespace's classes.

The reference indicates that you can use this assembly, and adding a using is to facilitate your use of this assembly, without writing the full name.
Such as:
After referencing System.Windows.Form, you can use the MessageBox.Show() method
But before you use System.Windows.Form, you must use it like this:
System.Windows.Form.MessageBox.Show()
When you add using System.Windows.Form in front of the code, you can easily use it directly:
MessageBox.Show()
The usage of "class.method"
Of course, I use static methods here, other methods need to instantiate the class first. Talk too much.
The simple point is: all you want to use must come from an assembly that you reference. Of course, many namespaces are often in an assembly, and you don’t need to refer to the same assembly multiple times for multiple namespaces.

There are many namespaces in an assembly
You can use the code in these namespaces by referring to an assembly, but write the full name, like ls said to write similar code such as System.Windows.Form.MessageBox.Show().
