Question

您好，我收到的错误是

数据阅读器与指定的内容不兼容 'TestSearch_Result'。一个成员 type，'Method'，数据中没有对应的列读者同名。

我已经彻底研究过这个问题，尝试了很多解决方案，没有任何效果。任何帮助都会很棒

定义表

PK Id

FK CourseId

FK TypeId

FK MethodId

名称

描述

IsActive

spTestSearch

Db.Model.Context.cs

    var NameParameter = Name != null ?
        new ObjectParameter("Name", Name) :

    var CourseIdListParameter = courseIdList != null ?
        new ObjectParameter("CourseIdList", courseIdList) :

    var TypeIdListParameter = TypeIdList != null ?
        new ObjectParameter("TypeIdList", TypeIdList) :
        new ObjectParameter("TypeIdList", typeof(string));


    return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<spTestSearch_Result>("spTestSearch", NameParameter, CourseIdListParameter, TypeIdListParameter);
}

问题可能是因为您正在检索存储过程中所有表的所有字段，并且它不会检索与TestSearch_Result对象的成员匹配的字段，在这种情况下它将是＆＃39;方法＆＃39;

类型为“方法”的成员在数据读取器中没有具有相同名称的相应列
