如何以编程方式从当前项目中构建和编译另一个c＃项目

Question

Program A: output ac# function, and insert the function into a file (eg. Classifier.cs) in another c# project B. These steps have already been implemented.

I am wondering is there any way to programmatically build and compile the the c# project B inside project A. So I can click a button in project A, it will automatically insert the new function into project B, build, compile the project B. And finally launch the new project B.

Thank you.

There are a lot of compilation assemblies for .NET that are now obsoletes. For compilation, use Microsoft.Build.

First, Add this following references :

• Microsoft.Build
• Microsoft.Build.Engine

Secondly, import :

using Microsoft.Build.Evaluation;

And finally, write this code :

var configuration = "Release";
var projectDirectory = @"C:\blabla";
var collection = ProjectCollection.GlobalProjectCollection;
var project = collection.LoadProject($@"{projectDirectory}\MyProject.csproj");
project.SetProperty("Configuration", configuration);

project.Build();

No need to execute a new process. .NET gives us a way to invoke the C# compiler programatically. I find this technique works well:

Assuming you're using Visual Studio you could just use run MSBuild against your ProjectB.csproj. That way you project should build identical to how it would build in Visual Studio.
