This is a recent development, there simply record what
Here there is a class, this class is very simple to demonstrate
public class OneClass
{
public Student StudentDb { get; set; }
public Teacher TeacherDb { get; set; }
public Location LocationDb { get; set; }
......//表示有很多这样的属性
public Equip EquipDb { get; set; }
}
Above this class, different properties may be returned corresponding to the class, such as OneClass().StudentDb
returns a Student
class OneClass().TeacherDb
returns a Teacher
class.
Then in the GetData()
process, according to the incoming class, to obtain the corresponding return type
, for example, passing a Student class I
public object GetData(Student t)
Then it should be returnedStudent
return OneClass().StudentDb
Be embodied using the following generic
public static object GetData<T>() where T : class, new()
{
//T代表传入的类型,比如GetData(Student)就表示传入了Student类
//获取类型
Type EntityType = typeof(T);
//获取要获取属性的类--这里是OneClass
Type DbE = typeof(OneClass);
try
{
//获取当前属性对象
PropertyInfo property = DbE.GetProperty(EntityType.Name + "Db");
//返回对象对应属性的值-并使用`as`来转换为传入的类对象
var result = property.GetValue(new DbEntities()) as T;
//这里的result就是返回的属性
return result;
}
catch { throw; }
}
