.net Core和Roslyn CSharpCompilation，类型'Object'在未引用的程序集中定义

本文介绍了 Core和Roslyn CSharpCompilation，类型'Object'在未引用的程序集中定义的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试将一些代码移植到新的Core运行时中，而移植一些即时编译时却遇到了麻烦。

I'm trying to port some code to the new Core runtime and I'm having a bad time porting some on-the-fly compilation.

要恢复，它总是要求我引用System.Runtime和mscorlib，但是不知道如何引用它们。

To resume, it always asks me for a reference to System.Runtime and mscorlib, but have no clue on how to reference them.

作为补充，我可以请参考Framework 4.6，因为必须将项目发布到具有 Core的Linux机器上。

As a side note, I can't reference Framework 4.6 as the project must be published to a Linux machine with Core.

这是最小代码：

string testClass = @"using System; namespace test{ public class tes { public string unescape(string Text) { return Uri.UnescapeDataString(Text); } } }"; var compilation = CSharpCompilation.Create(Guid.NewGuid().ToString() + ".dll") .WithOptions(new CSharpCompilationOptions(Microsoft.CodeAnalysis.OutputKind.DynamicallyLinkedLibrary)) .AddReferences( MetadataReference.CreateFromFile(typeof(Object).GetTypeInfo().Assembly.Location), MetadataReference.CreateFromFile(typeof(Uri).GetTypeInfo().Assembly.Location) ) .AddSyntaxTrees(CSharpSyntaxTree.ParseText(testClass)); var eResult = compilation.Emit("test.dll");

它总是抱怨需要mscorlib（在此示例中）和System.Runtime（在我的真实情况下）项目）。

It always complains about the need of mscorlib (in this example) and System.Runtime (in my real project).

我正在使用Microsoft.CodeAnalysis.CSharp软件包版本2.0.0-beta3

I'm using the Microsoft.CodeAnalysis.CSharp package version 2.0.0-beta3

关于如何使用Roslyn和 Core进行即时编译的任何想法？

Any ideas on how to compile on the fly with Roslyn and Core?

推荐答案

好，终于可以正常工作了：

Ok, got it finally working:

string testClass = @"using System; namespace test{ public class tes { public string unescape(string Text) { return Uri.UnescapeDataString(Text); } } }"; var dd = typeof(Enumerable).GetTypeInfo().Assembly.Location; var coreDir = Directory.GetParent(dd); var compilation = CSharpCompilation.Create(Guid.NewGuid().ToString() + ".dll") .WithOptions(new CSharpCompilationOptions(Microsoft.CodeAnalysis.OutputKind.DynamicallyLinkedLibrary)) .AddReferences( MetadataReference.CreateFromFile(typeof(Object).GetTypeInfo().Assembly.Location), MetadataReference.CreateFromFile(typeof(Uri).GetTypeInfo().Assembly.Location), MetadataReference.CreateFromFile(coreDir.FullName + Path.DirectorySeparatorChar + "mscorlib.dll"), MetadataReference.CreateFromFile(coreDir.FullName + Path.DirectorySeparatorChar + "System.Runtime.dll") ) .AddSyntaxTrees(CSharpSyntaxTree.ParseText(testClass)); var eResult = compilation.Emit("test.dll");

我不喜欢它，因为采用硬编码，但这似乎是使其工作的唯一途径

I don't like it because the hardcoding, but it seems it's the only way to get it work.
