.NET属性生成和QUOT;必须声明主体，因为它未标记为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）的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; }

这是给我这个编译错误，这些行：

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，这种风格的财产是作为.NET 3.0中有效。

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

谢谢！

原来，这个问题是在我的.sln文件本身。虽然我改变我的编译选项目标版本，在.sln文件，我发现这一点：

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"

更改，为3.5解决了这个问题。谢谢，伙计们！

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

推荐答案

添加到web.config文件

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" />

	</compilers>
</system.codedom>
