c# - VS 2017，直接 CSharpCodeProvider 使用 C#7

问题描述

在我的 xcript 中实现 C#7 功能（$- 字符串插值）并调用CSharpCodeProvider.CompileAssemblyFromSource()时，我收到以下错误：

E:\src\*****\****\bin\Debug> "C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe" 
/t:library /utf8output /R:"E:\***\***\Main\ConsoleApp1\bin\Debug\***.dll"

 0) E:\***\***\Main\***RuleEngine\_DynamicDll\TempFiles\5jdr2zw0.0.cs(549,35)

建造：

_csc = new CSharpCodeProvider(new Dictionary<string, string>() { { 
"CompilerVersion", "v4.0" } });

知道如何解决这个问题吗？

谢谢！
