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
    {

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。

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>
...

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)。

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

#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
