C# 如何获取实现规则列表-FluentValidations

使用WebAPI，我试图显示在属性上实现的规则

我正在使用Microsoft.AspNet.WebApi.HelpPage程序集，该程序集将为我的API生成帮助页。我希望能够枚举验证规则，以便在帮助页面上显示属性，如required和length

在前面，我将对自定义属性执行以下操作：

-- namespace MyAPI.Areas.HelpPage.ModelDescriptions

private readonly IDictionary<Type, Func<object, string>> AnnotationTextGenerator =
    new Dictionary<Type, Func<object, string>>
    {
        { typeof(MyAttribute), a => "My Attribute Documentation" }
    };

当调用这个GenerateAnnotations例程时，我想添加一个逻辑，它将查看属性并获得所有指定的fluent属性，然后添加文本

也许可以用这个来优雅地列举属性

-- namespace MyAPI.Areas.HelpPage.ModelDescriptions
/// <summary>   Generates the annotations. </summary>
/// <param name="property">         The property. </param>
/// <param name="propertyModel">    The property model. </param>
private void GenerateAnnotations(MemberInfo property, ParameterDescription propertyModel)
{
    var annotations = new List<ParameterAnnotation>();

    var attributes = property.GetCustomAttributes();
    foreach (var attribute in attributes)
    {
        Func<object, string> textGenerator;
        if (AnnotationTextGenerator.TryGetValue(attribute.GetType(), out textGenerator))
        {
            annotations.Add(
                new ParameterAnnotation
                {
                    AnnotationAttribute = attribute,
                    Documentation = textGenerator(attribute)
                });
        }
    }

    // Rearrange the annotations
    annotations.Sort(
        (x, y) =>
        {
            // Special-case RequiredAttribute so that it shows up on top
            if (x.AnnotationAttribute is RequiredAttribute)
            {
                return -1;
            }
            if (y.AnnotationAttribute is RequiredAttribute)
            {
                return 1;
            }

            // Sort the rest based on alphabetic order of the documentation
            return String.Compare(x.Documentation, y.Documentation, StringComparison.OrdinalIgnoreCase);
        });

    foreach (var annotation in annotations)
    {
        propertyModel.Annotations.Add(annotation);
    }
}
