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**)
    /// <returns>A newly created item</returns>
    /// <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>
    [ProducesResponseType(typeof(Service), 201)]
    [ProducesResponseType(400)]
    [ProducesResponseType(409)]
    [ProducesResponseType(500)]
    [HttpPost]
    public async Task<ActionResult> ServiceCreate([FromBody] ServicePostRequest service,
#pragma warning disable 1573  
        CancellationToken cancellationToken = default) //**note: no warning**
#pragma warning restore 1573
    {

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。

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。

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
