Dear All,
I create a BaseControlLibrary.csproj and add 3 controls to it. I plan to include all common controls. Then I create a Library.cs. I want to get access to the code in the Library.cs from a control in the BaseControlLibray.csproj.
Solution
Error
Here is an idea, purchase Resharper, it will fix the current issue, help you learn and much, much more. pricing is per year but if you purchase a single year it works for future years but no upgrades.
Thanks for your suggestion. I am still learning c#. I may change to another language. Thus I will not buy it.
Hi @AgaveJoe
Your approach only fixes the error in a class of BaseControlLibrary. However, my problem is calling the "Library.cs" from a Control of the "BaseControlLibrary". Now it consists of many 3 Controls Panel, Button, and CheckBox. In the future, I will add other Controls to "BaseControlLibrary". My screen capture for the "Panel.cs" shows this problem. I don't know how to fix it. Please help!
Your approach only fixes the error in a class of BaseControlLibrary.
Correct! That was my intension, since you need to reference the Lib class in the BaseControlLibrary.
However, my problem is calling the "Library.cs" from a Control of the "BaseControlLibrary".
Can you show us code example of what you mean by calling "Library.cs" from a Control of the "BaseControlLibrary"? It would be very helpful if you share the entire solution on GitHub. That will give us a better idea of what you are doing.
by the way, there is nothing stopping you from invoking the Lib class in a derived user control class.
using System.Windows.Forms;
using Library;
namespace BaseControlLibrary
{
public partial class Panel: UserControl
{
private Lib lib;
public Panel()
{
InitializeComponent();
lib = new Lib();
}
protected void DoSomething()
{
string results = lib.String("string1", 10);
}
}
}
The sample code above illustrates how to define the Lib class as a Panel member field, instantiate the Lib class in the Panel constructor, and call a Lib method. This answer your original question. This does not mean the Lib class and general design is fundamentally correct or will produce the expected results.
Hi @AgaveJoe
Thanks for your reply. After ensuring all references follow your instruction, I copy your code to my Visual Studio. However. "errors" are still shown. Please tell me how to fix the errors.

I'm not sure what you're doing wrong. First, you should place the cursor over the error to read the error message.
A help image should popup and provide solutions.
Otherwise commit your entire solution to GitHub so the community find the mistakes in your solution.
Hi @AgaveJoe
I'm planning to upload the entire solution to GitHub. Therefore I ask how in this forum. My question is as follows.
Upload the solution NewTims' code to GitHub from Visual Studio without overwriting the original NewTims' code? The tool that I am using is Visual Studio.
