我想对这里列出的答案补充一些东西:

正如Isak所指出的，XML文档对于类库非常有用，因为它为Visual Studio中的任何消费者提供了智能感知。因此，一个简单而正确的解决方案是关闭任何顶级项目(如UI等)的文档，因为它不会在自己的项目之外实现。

此外，我想指出的是，警告只表示在公开可见的成员。因此，如果将类库设置为只公开它需要公开的内容，则无需记录私有成员和内部成员。

5个选项:

Fill in the documentation comments (great, but time-consuming) Turn off the comment generation (in project properties) Disable the warning in project properties (in 'Project properties' go to Project properties -> Build > "Errors and warnings" (section), Suppress Warnings (textbox), add 1591 (comma separated list)). By default it will change Active Configuration, consider to change configuration to All. Use #pragma warning disable 1591 to disable the warning just for some bits of code (and #pragma warning restore 1591 afterwards) Ignore the warnings (bad idea - you'll miss new "real" warnings)

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

#pragma warning disable 1591
#pragma warning disable 1591
#pragma warning disable 1572
#pragma warning disable 1571
#pragma warning disable 1573
#pragma warning disable 1587
#pragma warning disable 1570

Jon Skeet的回答非常适用于使用VisualStudio进行构建。但是，如果您通过命令行构建sln(在我的例子中是通过Ant)，那么您可能会发现msbuild忽略sln抑制请求。

添加到msbuild命令行解决了我的问题:

/p:NoWarn=1591

插入一个XML注释。: -)

/// <summary>
/// Describe your member here.
/// </summary>
public string Something
{
    get;
    set;
}

乍一看，这似乎是个笑话，但实际上可能很有用。对我来说，思考方法对于私有方法的作用是有帮助的(当然，除非非常琐碎)。
