将警告级别设置为2将抑制此消息。不知道这是否是最好的解决方案，因为它也抑制了有用的警告。

还有另一种方法可以抑制这些消息，而不需要任何代码更改或pragma块。使用Visual Studio -转到项目属性>构建>错误和警告>抑制警告-将1591附加到警告代码列表。

I know this is a really old thread, but it's the first response on google so I thought I'd add this bit of information: This behavior only occurs when the warning level is set to 4 under "Project Properties" -> "Build". Unless you really need that much information you can set it to 3 and you'll get rid of these warnings. Of course, changing the warning level affects more than just comments, so please refer to the documentation if you're unsure what you'll be missing: https://msdn.microsoft.com/en-us/library/thxezb7y.aspx

您需要为显示警告的成员添加/// Comment。

参见下面的代码

public EventLogger()
{
    LogFile = string.Format("{0}{1}", LogFilePath, FileName);
}

显示警告 缺少公开可见类型或成员'.EventLogger()'的XML注释

我为成员添加了评论，警告消失了。

///<Summary>
/// To write a log <Anycomment as per your code>
///</Summary>
public EventLogger()
{
    LogFile = string.Format("{0}{1}", LogFilePath, FileName);
}

一个非常简单的方法是在.csproj文件中添加一个属性:

<Project>
    <PropertyGroup>
        ...     
        <!--disable missing comment warning-->
        <NoWarn>$(NoWarn);1591</NoWarn>
    </PropertyGroup>
...

在将一个属性附加到一个方法后，我得到了这条消息

[webMethod]
public void DoSomething()
{
}

但正确的做法是:

[webMethod()] // Note the Parentheses 
public void DoSomething()
{
}
