来自@JonSkeet的答案几乎完成了。如果您想为解决方案中的每个项目禁用它，可以将下面的行添加到.editorconfig文件中。

dotnet_diagnostic.CS1591.severity = none

查看文件层次结构和优先级添加文件的位置:

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)

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..

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。

在这里的后面，但是这个线程中的许多解决方案都专注于在项目或类中完全删除警告。

如果你想保留合法的警告，但删除一些-例如，当你使用swagger公开API时，WebApi控制器上的cancellationToken (API用户不需要这个-它是由DI提供的)。

很难看，但至少在这种情况下，取消令牌是最后一个参数。

    /// <summary>
    /// Creates a Service
    /// </summary>
    /// <param name="service">The Service Definition</param> (**note no cancellation token param**)

    /// <response code="201">Returns the newly created service</response>
    /// <response code="400">If there are validation errors with the submitted json body</response>
    /// <response code="409">Conflict. The service already exists</response>
    /// <response code="500">Because life is never perfect</response>
