Detailed introduction to mixed development and testing of C# and VB.net (pictures and text)

In the past, programming software was basically developed using a development language, either C#, Java, or Delphi. Recently, I have seen some development methods of merging multiple C# projects into one solution, and I think this method is good. Below we will create a simple example to experience the charm of Microsoft platform multi-language development.

Development process:

1. Create a new C# Windows program project

2. Create a new VBclass library project

Add the class library to the C# project just now ("Add Solution")

After building the project, the following picture is shown:

3. Write VB class library code

Create a new test method SayHello() and simply output information prompts.

4. Add project Reference

Add project reference in C# project, that is, VB project.

5. Design forms and write C# formsEventCode

# #

using System;
using System.Windows.Forms;

using ClassLibrary1;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            new Class1().SayHello();        
        }
    }
}

##Multi-project mixed development mainly has the following benefits:

Layered design, each Layers can be developed independently to facilitate division of labor;

Just add references between different projects. After compilation, it will be a

l file. When publishing, you can decide whether to publish Dll or source code according to your needs;

facilitates the formation of code assets. In the future, similar projects only need to reference related projects to avoid citing redundant code; There is another point that other language platforms cannot reach now. What is achieved is that the advantages of different languages ​​​​under the .net platform can be used, and programmers using different languages ​​​​can jointly develop a project.
