是否可以在新的.Net Core(更好的.Net Standard Platform)中在运行时编译和运行C#代码?我已经看到了一些示例(.Net Framework),但是它们使用了与netcoreapp1.0(.NETCoreApp,Version = v1.0)不兼容的NuGet软件包
Is it possible to compile and run C# code at runtime in the new .Net Core (better .Net Standard Platform)? I have seen some examples (.Net Framework), but they used NuGet packages that are not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0)
推荐答案选项#1 :使用完整的C#编译器编译程序集,加载程序集,然后从中执行方法。
Option #1: Use the full C# compiler to compile an assembly, load it and then execute a method from it.
这需要以下软件包作为project.json中的依赖项:
This requires the following packages as dependencies in your project.json:
"Microsoft.CodeAnalysis.CSharp": "1.3.0-beta1-20160429-01", "System.Runtime.Loader": "4.0.0-rc2-24027",然后您可以使用如下代码:
Then you can use code like this:
var compilation = CSharpCompilation.Create("a") .WithOptions(new CSharpCompilationOptions(OutputKind.DynamicallyLinkedLibrary)) .AddReferences( MetadataReference.CreateFromFile(typeof(object).GetTypeInfo().Assembly.Location)) .AddSyntaxTrees(CSharpSyntaxTree.ParseText( @" using System; public static class C { public static void M() { Console.WriteLine(""Hello Roslyn.""); } }")); var fileName = "a.dll"; compilation.Emit(fileName); var a = AssemblyLoadContext.Default.LoadFromAssemblyPath(Path.GetFullPath(fileName)); a.GetType("C").GetMethod("M").Invoke(null, null);选项#2 :使用Roslyn脚本,这将导致更简单的代码,但当前需要更多设置:
Option #2: Use Roslyn Scripting. This will result in much simpler code, but currently requires more setup:

创建NuGet.config可以从Roslyn夜间供稿中获取软件包:
Create NuGet.config to get packages from the Roslyn nightly feed:
将以下软件包作为依赖项添加到project.json(注意,这是从今天开始的软件包,您需要ent版本):
Add the following package as a dependency to project.json (notice that this is package from today, you will need different version in the future):
"Microsoft.CodeAnalysis.CSharp.Scripting": "1.3.0-beta1-20160530-01",您还需要导入 dotnet (已过时的 Target Framework Moniker,尽管如此,罗斯林仍然使用):
You also need to import dotnet (obsolete "Target Framework Moniker", which is nevertheless still used by Roslyn):
"frameworks": { "netcoreapp1.0": { "imports": "dotnet5.6" } }
现在您终于可以使用脚本了:
Now you can finally use Scripting:
CSharpScript.EvaluateAsync(@"using System;Console.WriteLine(""Hello Roslyn."");").Wait();
