在CodeDomProvider（Roslyn）中使用C＃6功能 [英] Using C# 6 features with CodeDomProvider (Roslyn)

问题描述

CodeDomProvider objCodeCompiler = CodeDomProvider.CreateProvider( "CSharp" );

CompilerParameters objCompilerParameters = new CompilerParameters();

...

CompilerResults objCompileResults = objCodeCompiler.CompileAssemblyFromFile( objCompilerParameters, files.ToArray() );

编译文件时，我得到：

FileFunctions.cs（347）：错误：意外字符'$'

FileFunctions.cs(347): Error: Unexpected character '$'

有人知道如何

我找到了此链接：如何使用CSharpCodeProvider定位.net 4.5？

所以我尝试了：

     var providerOptions = new Dictionary<string, string>();
     providerOptions.Add( "CompilerVersion", "v4.0" );

     // Instantiate the compiler.
     CodeDomProvider objCodeCompiler = CodeDomProvider.CreateProvider( "CSharp", providerOptions );

但是我仍然遇到相同的错误。

But I still get the same error.

我还将目标框架更新为.NET Framework 4.6。

I also updated the target framework to .NET Framework 4.6.

注意：我无法指定 v4.5或 v4.6，否则我将得到：

NOTE: I can't specify "v4.5" or "v4.6" or I will get:

我尝试使用Thomas Levesque的建议：

I have tried using the suggestion by Thomas Levesque:

CodeDomProvider objCodeCompiler = new Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider();

但是我得到：

************** Exception Text **************
System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\Derek.Morin\Documents\Visual Studio 2010\Projects\ScriptCode\ScriptCode.ConvertedToC#\bin\x86\Debug\bin\roslyn\csc.exe'.

我不确定为什么要在我的bin目录的子文件夹中查找 csc.exe。

I'm not sure why it is trying to look for "csc.exe" in a subfolder of my bin directory.

此路径存在：

C：\Users\Derek.Morin\Documents\Visual Studio
2010\Projects\ScriptCode\ScriptCode.ConvertedToC＃\bin\ x86\Debug\roslyn

C:\Users\Derek.Morin\Documents\Visual Studio 2010\Projects\ScriptCode\ScriptCode.ConvertedToC#\bin\x86\Debug\roslyn

但是它正在寻找：

C：\Users\Der ek.Morin\Documents\Visual Studio
2010\Projects\ScriptCode\ScriptCode.ConvertedToC＃\bin\x86\Debug\bin\roslyn\csc.exe

C:\Users\Derek.Morin\Documents\Visual Studio 2010\Projects\ScriptCode\ScriptCode.ConvertedToC#\bin\x86\Debug\bin\roslyn\csc.exe

推荐答案

内置的CodeDOM提供程序不支持C＃6。请改用此代码：

The built-in CodeDOM provider doesn't support C# 6. Use this one instead:

https://www.nuget.org/ packages / Microsoft.CodeDom.Providers.DotNetCompilerPlatform /

它基于Roslyn，并支持C＃6功能。

It's based on Roslyn and supports the C# 6 features.

只需更改以下行：

CodeDomProvider objCodeCompiler = CodeDomProvider.CreateProvider( "CSharp" );

为此：

CodeDomProvider objCodeCompiler = new Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider();
