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()
{
}

禁止XML注释的警告

(不是我的作品，但我发现它很有用，所以我包含了文章和链接)

Here i will show you, how you can suppress warnings for XML comments after a Visual Studio build. Background If you have checked the "XML documentation file" mark in the Visual Studio project settings, a XML file containing all XML comments is created. Additionally you will get a lot of warnings also in designer generated files, because of the missing or wrong XML comments. While sometimes warnings helps us to improve and stabilize our code, getting hundreds of XML comment warnings is just a pain. Warnings Missing XML comment for publicly visible type or member … XML comment on … has a param tag for ‘…’, but there is no parameter by that name Parameter ‘…’ has no matching param tag in the XML comment for ‘…’ (but other parameters do) Solution You can suppress every warning in Visual Studio. Right-click the Visual Studio project / Properties / Build Tab Insert the following warning numbers in the "Suppress warnings": 1591,1572,1571,1573,1587,1570

当然要向公开可见的类型和成员添加XML注释:)

///<Summary>
/// Gets the answer
///</Summary>
public int MyMethod()
{
   return 42;
}

所有成员都需要这些<summary>类型的注释——这些注释也会显示在智能感知弹出菜单中。

得到此警告的原因是因为您已经将项目设置为输出文档xml文件(在项目设置中)。这对于类库(.dll程序集)很有用，这意味着.dll的用户可以在visual studio中获得API的智能感知文档。

我建议你买一份GhostDoc Visual Studio插件。使记录变得更容易。

这是因为您的项目属性中指定了一个XML文档文件，而您的方法/类是公共的，缺乏文档。 你可以:

禁用XML文档: 右键单击您的项目->属性->“构建”选项卡->取消选中XML文档文件。 坐下来自己写文档吧!

XML文档的总结如下:

/// <summary>
/// Description of the class/method/variable
/// </summary>
..declaration goes here..

文件>编辑>查看项目(点击)

下拉弓的底部(点击打开/当前工作>属性)， 打开项目属性页在“构建”下的“输出”。取消选中“XML文档”复选框。

重建，没有警告。

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
