WebApiTestClient是基于微软HelpPage一个客户端调试扩展工具，用来做接口调试比较方便。但是对返回值的自定义说明还是有缺陷的。有园友，说可以通过对类进行注释，然后通过在IHttpActionResult上标记ResponseType(typeof(class))即可。

[ResponseType(typeof(CreditRuleDetails))]        public IHttpActionResult GetCreditRuleList(int ruleType = 1)        {            try            {                     }            catch (Exception exception)            {            }        }

CreditRuleDetails类

public class CreditRuleDetails{ /// 
 /// 规则Id/// 
public int RuleId{get;set;} /// 
 /// 规则名称/// 
public int RuleName{get;set;}}

　　但发现返回值的Description中没有summary描述。

弄了半天，也没发现是什么问题，后来转变了下思路。改用C#特性来做，然后更改了下ModelDescriptionGenerator.cs的方法实现。

private ModelDescription GenerateComplexTypeModelDescription(Type modelType)        {            ComplexTypeModelDescription complexModelDescription = new ComplexTypeModelDescription            {                Name = ModelNameHelper.GetModelName(modelType),                ModelType = modelType,                Documentation = CreateDefaultDocumentation(modelType)            };            GeneratedModels.Add(complexModelDescription.Name, complexModelDescription);            bool hasDataContractAttribute = modelType.GetCustomAttribute
     
      () != null;            PropertyInfo[] properties = modelType.GetProperties(BindingFlags.Public | BindingFlags.Instance);            foreach (PropertyInfo property in properties)            {                if (ShouldDisplayMember(property, hasDataContractAttribute))                {                    ParameterDescription propertyModel = new ParameterDescription                    {                        Name = GetMemberName(property, hasDataContractAttribute)                    };                    if (DocumentationProvider != null)                    {                        //======以下是添加的=========                        DescriptionAttribute myattribute = (DescriptionAttribute)Attribute.GetCustomAttribute(property, typeof(DescriptionAttribute));                        if (myattribute != null)                        {                            propertyModel.Documentation = myattribute.Description;                        }                        //========以上是添加的===========                        else                        {                            propertyModel.Documentation = DocumentationProvider.GetDocumentation(property);                        }                    }
     

然后将类的属性标记为Description。

[Description("规则名称")]        public string RuleName { get; set; }

最后结果：
