Roslyn 可以用于 VB.NET 脚本吗? [英] Can Roslyn be used for VB.NET scripting?

问题描述

我正在为我的应用程序创建一个脚本编辑器，我希望它能够使用 Roslyn 运行 C# 和 VB.NET 脚本.我通过使用 Microsoft.CodeAnalysis.CSharp.Scripting 程序集/命名空间中的 CSharpScript 类来使用 C#，但是没有等效的 VisualBasicScript 我能找到的类，也不是 Microsoft.CodeAnalysis.VisualBasic.Scripting 程序集.我在网上搜索过，没有发现任何关于运行 VB.NET 脚本的有用信息，而且 Roslyn github 站点上的所有示例都是 C# 特定的.我是不是遗漏了什么，或者对运行 VB.NET 脚本的支持根本不存在，就像它对 C# 脚本所做的那样?

I'm creating a script editor for my application, and I'd like to have it be able to run both C# and VB.NET scripts using Roslyn. I got this working with C# by using the CSharpScript class in the Microsoft.CodeAnalysis.CSharp.Scripting assembly/namespace, however there is no equivalent VisualBasicScript class that I can find, nor a Microsoft.CodeAnalysis.VisualBasic.Scripting assembly. I've scoured the web and can find nothing useful about running VB.NET scripts, and all the samples on the Roslyn github site are C#-specific. Am I missing something, or does support for running VB.NET scripts simply not exist the way it does for C# scripts?

推荐答案

目前没有 Visual Basic Sc​​ripting可用，大概是因为尚未完成.

但是它的来源是 Roslyn repo，所以你可以尝试自己构建它.

But its source is is the Roslyn repo, so you could try building it yourself.

当我这样做时，如下代码对我有用:

When I do that, code like the following works for me:

Dim result = VisualBasicScript.RunAsync("Dim result = 1+1").Result

For Each variable In result.Variables
    Console.WriteLine($"{variable.Name}: {variable.Value}")
Next

但是这段代码对我不起作用(编译脚本时失败):

But this code does not work for me (it fails when compiling the script):

Console.WriteLine(VisualBasicScript.EvaluateAsync("1+1").Result)

我不确定这是因为它还没有完成，还是故意与 C# 脚本有所不同.

I'm not sure whether this is because it's not finished, or whether it's intentional difference from C# scripting.
