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('_')[1];    
    ColumnInfo identityKey=host.IdentityKey;
    string returnValue = "void";
    if (identityKey!=null)
    {         
         returnValue = CodeCommon.DbTypeToCS(identityKey.TypeName);              
    }
