.NET属性生成“必须声明一个主体，因为它没有标记为abstract或extern”编译错误 [英] .NET property generating "must declare a body because it is not marked abstract or extern" compilation error

问题描述

我有一个.NET 3.5（目标框架）Web应用程序。我有一些代码看起来像这样：

I have a .NET 3.5 (target framework) web application. I have some code that looks like this:

public string LogPath { get; private set; }
public string ErrorMsg { get; private set; }

这些行给我这个编译错误：

It's giving me this compilation error for these lines:

"must declare a body because it is not marked abstract or extern."

任何想法？我的理解是，这种风格的属性是有效的.NET 3.0。

Any ideas? My understanding was that this style of property was valid as of .NET 3.0.

谢谢！

问题出在我的.sln文件本身。虽然我在我的构建选项更改目标版本，在.sln文件中，我发现：

The problem turned out to be in my .sln file itself. Although I was changing the target version in my build options, in the .sln file, I found this:

TargetFramework = "3.0"

将其更改为3.5即可解决问题。非常感谢！

Changing that to "3.5" solved it. Thanks, guys!

推荐答案

添加到web.config

add to web.config

<system.codedom>
    <compilers>
        <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">
            <providerOption name="CompilerVersion" value="v3.5" />
            <providerOption name="WarnAsError" value="false" />
        </compiler>
    </compilers>
</system.codedom>
