在指定摘要标记注释时,是否有一种方法可以使用<param>标记来指出参数是可选的,即。客户端可以提供值或null,例如:<param name="Mime" optional="true">.

Google搜索无法向我提供属性或允许值的设置列表。

/// <summary>
/// Sets data associated with instance
/// </summary>
/// <param name="Key">The key defining the data</param>
/// <param name="Value">The data</param>
/// <param name="Mime">The mime type of the data (optional)</param>     <----- Mark as optional

不,你不能。 VS识别的唯一属性是name,如下所示:

<param name="FileName" >The filename of the file to be loaded.</param>

您唯一能做的就是为输出文档设置xsl transform。但这对Intellisense没有任何影响。

您可以使用<remarks></remarks>标记。不存在可选参数的特殊标记。

您应该提供省略可选参数的重载:

/// <summary>
/// Sets data associated with the instance using the default media type.
/// </summary>
/// <param name="key">The key defining the data.</param>
/// <param name="value">The data.</param>
public void SetData(object key, object value)
{
    SetData(key, value, null);
}

/// <summary>
/// Sets data associated with the instance using the specified media type.
/// </summary>
/// <param name="key">The key defining the data.</param>
/// <param name="value">The data.</param>
/// <param name="mime">The media type of the data.</param>
public void SetData(object key, object value, string mime)
{
    ...
}

或者,您可以将参数声明为可选:

/// <summary>
/// Sets data associated with the instance.
/// </summary>
/// <param name="key">The key defining the data.</param>
/// <param name="value">The data.</param>
/// <param name="mime">The media type of the data.</param>
public void SetData(object key, object value, string mime = null)
{
    ...
}
