Cshtml文件中的C#6.0功能的Resharper问题

我刚刚在Windows 10(1703)上安装了一台配备VS2017 Pro(15.2)和Resharper(2017.1.2)的新PC。

我已经打开了现有解决方案,Resharper突出了CSHTML文件中的大量问题。我所看到的都是字符串插值和空条件运算符,消息是" C#6.0语言功能",好像这是一个错误。所有项目仍然编译并运行正常,字符串插值和空条件运算符不会突出显示为普通CS文件中的错误。

解决方案中的项目都设置为Framework 4.6.1,C#语言级别设置为Default。我已在CSharp60文件中将LanguageLevel设置为sln.DotSettings,现在所有项目都将语言级别显示为C# 6.0,但Resharper仍然对字符串抱怨插值误差。清除Resharper缓存没有帮助。

该解决方案在最近安装的另一台PC上运行,完全没有错误。唯一的区别是,在另一台PC上,它是一个全新的构建,而这个构建是新的C:\驱动器上的新操作系统,但代码是在第二个没有被更改的驱动器上。

我的views文件夹中的web.config如下所示:

<?xml version="1.0"?>

<configuration>

主web.config的codedom部分看起来像这样

 <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:default /nowarn:1659;1699;1701" />

    </compilers>
  </system.codedom>

尝试将编译器标志设置为/langversion:6而不是default。 ReSharper似乎试图将版本解析为一个数字,这将失败并将ReSharper保留在C#5。

<system.codedom>
  <compilers>
    <compiler language="c#;cs;csharp" 
              extension=".cs"
              type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
              warningLevel="4"
              compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
    <compiler language="vb;vbs;visualbasic;vbscript"
              extension=".vb"
              type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
              warningLevel="4"
              compilerOptions="/langversion:6 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />

除了citizenmatt的回答,Resharper不支持import operator import functools import itertools indexes = [('children', '0'), ('children', '9'), ('product', '')] # This turns the list above into a flat list ['children', 0, 'children', ...] # It also converts number strings to integers and excludes empty strings. keys = (int(k) if k.isdigit() else k for k in itertools.chain(*indexes) if k) # functools.reduce recursively looks up the keys # operator.getitem() is a functional version of Data[key] == getitem(Data, key) value = functools.reduce(operator.getitem, keys, Data) if value == expected: pass 标记。在这种情况下,您需要将<location>块移到<system.codedom>块之外。
