小巧玲珑的C＃：拆分列类型对象为TYPEID和类型名

Question

我使用短小精悍，并要分割

Class EType 
{ 
    int TypeID; 
    string TypeName; 
} 

Class Employee 
{ 
    int id; 
    string location; 
    EType EmpType; 
} 

Employee表：

ID||Location||TypeID||TypeName 

在CRUD操作使用小巧精致，我想的empType的转换自动分为数据库中的相应列。引用类型处理程序和自定义地图。 ？但没有运气:(

任何帮助，请

首先，你必须使用属性，而不是字段然后用精致小巧的multi-mapping：

public class Employee 
{ 
    public int Id { get; set; } 
    public string Location { get; set; } 
    public EType EType { get; set; } 
} 

public class EType 
{ 
    public int TypeId { get; set; } 
    public string TypeName { get; set; } 
} 

[TestFixture] 
public class MultimappingTest 
{ 
    [Test] 
    public void TestSplit() 
    { 
     using (var conn = new SqlConnection(@"Data Source=.\sqlexpress;Integrated Security=true; Initial Catalog=foo")) 
     { 
      var result = 
       conn.Query<Employee, EType, Employee>(@"select Id = 1, Location = 'earth', TypeId = 2, TypeName = 'human'", 
        (employee, type) => 
        { 
         employee.EType = type; 
         return employee; 
        }, splitOn: "TypeId").First(); 

      Assert.That(result.EType.TypeId == 2); 
      Assert.That(result.EType.TypeName == "human"); 
     } 
    } 
}
