步步为营-60-代码生成器

说明:代码生成器有很多,我们目前介绍的是动软代码生成器

1 打开动软,连接数据库,新建项目,选择要生成的表和地址,生成

2 自定义模板生成

    string DALSpace= host.NameSpace+".DAL."+ host.GetDALClass(host.TableName);
    ColumnInfo identityKey=host.IdentityKey;
    string returnValue = "void";
    if (identityKey!=null)
    {         
         returnValue = CodeCommon.DbTypeToCS(identityKey.TypeName);
