Question

在c#中bll项目里面的封装业务逻辑类如何引用dal项目，代码详细一点，谢谢！

Answer 1

Bll添加Dal的引用
namespace Compact.BLL
{
/// <summary>
/// Users
/// </summary>
public partial class Users
{
private readonly Compact.DAL.Users dal=new Compact.DAL.Users();
public Users()
{}
#region Method

/// <summary>
/// 得到最大ID
/// </summary>
public int GetMaxId()
{
return dal.GetMaxId();
}
}
}

namespace Compact.DAL
{
/// <summary>
/// 数据访问类:Users
/// </summary>
public partial class Users
{
public Users()
{}
#region Method

/// <summary>
/// 得到最大ID
/// </summary>
public int GetMaxId()
{
return DbHelperSQL.GetMaxID("User_id", "Users");
}
}
}
