MVC+Ninject+三层架构+代码生成 -- 总结（六、邏輯層）

1.邏輯層的方法應該與數據層的方法一一對應。邏輯層返回的結果都是用接口IResult封裝，用於項目轉換時，能減少變化的代碼量。

2.邏輯層都需要繼承 BaseLogic 類

  public  class BaseLogic

    {

        public T NewObject<T>() where T : class

        {

            T t = IOCHelper.GetInstance<T>();

            return t;

        }

    }

3.動軟代碼

<#@ template language="c#" HostSpecific="True" #>

<#@ output extension= ".cs" #>

<#

    TableHost host = (TableHost)(Host);

    string ModelSpace = host.NameSpace+".Model."+ host.GetModelClass(host.TableName);

    string DALSpace= host.NameSpace+".DAL."+ host.GetDALClass(host.TableName);

    string TableName =  host.GetModelClass(host.TableName).Split('_')[];

    ColumnInfo identityKey=host.IdentityKey;

    string returnValue = "void";

    if (identityKey!=null)

    {

         returnValue = CodeCommon.DbTypeToCS(identityKey.TypeName);

    }
