可以在一个项目中引用两个具有相同名称的不同程序集吗？ 不同的二进制文件

Question

this is a strange one...maybe.

Summary: I'm using the 32feet libraries for bluetooth communication. We have shared code which runs on both .Net compact (for mobile) and standards. Net.

I'm searching for a suggestive solution or some design pattern that may exist that I'm not aware of.

32feet provides one assembly for compact framework and one for standard. Assemblies have the same name, same class names.

I need to come up with a solution where I have a generic class which anyone can consume that will know how is connecting. I am not even sure if this is possible. The solution im leaning towards so far is having two separate assemblies... One for mobile. .. One for standard. It doesn't feel right and I'm wondering if there's a better route to go. Is it possible to use so sort of DI to choose the correct binary at runtime?

Example:

Public abstract BluetoothBase
{
     Public BluetoothBase ()
     {
     }

     Public int Connect ()
     {
          // this is where problem lies.  Need to tell class which assembly to use based on OS.  So far I'm finding this is not possible. ..
     }
}

Answer 1

This would be adding an interface and 2 implementations that need to be maintained but this I think would accomplish what you are going for.

Define a interface in the shared code.

public interface IBluetooth
{
    //methods you need from the base class.
}

In the mobile platform specific code

public class MobileBluetooth : IBluetooth
{
//Implement
}

In the desktop platform specific code

public class DesktopBlueooth : IBluetooth
{
    //Implement
}

And for your framework or bluetooth base class have an initialize method where you inject in your interface.

public abstract BluetoothBase
{
    private IBluetooth _connection;

    public Init(IBluetooth connection)
    {
        _connection = connection;
    }

    public int Connect()
    {
         //use the interface to connect.
    }
}

In short, the easiest way to do this is the following:

You have two assemblies with the exact same name, same class types, same everything. Only difference? I my case one was compiled for desktop while the other was compiled for compact framework

I this case the assemblies are called InTheHand.Personal.Net

The easiest approach is to do the following:

1. Copy each respective assembly to its own folder.

2. In visual studio, right click on your project and select "unload project". This is necessary because the reference manager will not allow you to add two assemblies with the same name. To get around this you manually edit the project file.

3. Add two reference elements to three reference section. Each one pointing to the path location of the dll.

4. Give each. Dll is own alias.

The in you're code, just use the extern alias directive to reference each assembly.

If you're doing mobile versus nonmobile like me, wrap each one in a #if PocketPC directive

Then create a using alias to each
