C#实现_______个人记账程序
本程序的基本框架代码或者说大部分代码是来自北风网老师的C#家庭理财项目的那个视频。
自己在这实现了一遍，其中做了一点优化，其中很多地方存在问题，以及没有进行所有功能的实现。
所有代码(带详细注释)如下:
下面是登陆框界面的代码：

为方便数据库操作而写的类如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
namespace Finace
{
/// <summary>
/// 功能：方便数据库操作（注册）

class DBOperate
{
private static string connString = "Data Source =(local);Initial Catalog =FinanceProject; User Id =sa ; Password =merlin ";
public static SqlConnection connection = new SqlConnection(connString);
}
}
