菜单分级
static void Main(string[] args) //主函数
{
zhucaidan();
Console.ReadKey();
}
static void zhucaidan()
{
Console.Clear();
Console.WriteLine("");
Console.WriteLine(" ++++++++++++++++++++欢迎进入图书管理系统++++++++++++++++");
Console.WriteLine("");
panduan:
Console.WriteLine(" * 添加图书信息请按1\n * 修改图书信息请按2\n * 查询图书信息请按3");
string i = Console.ReadLine();
if (i == "1")
{
tianjia();
}
else if (i == "2")
{
xiugai();
}
else if (i == "3")
{
chaxun();
}
else
{
Console.Clear();
Console.WriteLine("请按提示选择");
goto panduan;
}
Console.WriteLine();
}
static void tianjia()//添加
{
Console.Clear();
Console.WriteLine("");
Console.WriteLine(" ++++++++++++++++++++图书添加管理+++++++++++++++++++++");
Console.WriteLine("");
Console.WriteLine(" 请输入所添加的图书信息 若要返回，请按f键");
string i = Console.ReadLine();
if (i == "f")
{
zhucaidan();
}
}
static void xiugai()//修改
{
fanhui:
Console.Clear();

Console.WriteLine(" ++++++++++++++++++++图书信息修改+++++++++++++++++++");
Console.WriteLine("");
Console.WriteLine("修改图书作者请按1，修改图书名字请按2，修改图书编号请按3，修改图书出版社请按4");
Console.WriteLine(" 返回主菜单请按f");
string i = Console.ReadLine();
if (i == "1")
{
Console.WriteLine("请选择所需要修改的图书的作者");
Console.WriteLine(" 返回上一级菜单请按f");
string j = Console.ReadLine();
if (j == "f")
{
xiugai();
}
}
else if (i == "2")
{
Console.WriteLine("请选择所需要修改的图书的书名");
Console.WriteLine(" 返回上一级菜单请按f");
string j = Console.ReadLine();
if (j == "f")
{
xiugai();
}
}
else if (i == "3")
{
Console.WriteLine("请选择所需要修改的图书的编号");
Console.WriteLine(" 返回上一级菜单请按f");
string j = Console.ReadLine();
if (j == "f")
{
xiugai();
}
}
else if (i == "4")
{
Console.WriteLine("请选择所需要修改的图书的出版社");
Console.WriteLine(" 返回上一级菜单请按f");
string j = Console.ReadLine();
if (j == "f")
{
xiugai();
}
}
else if (i == "f")
{
zhucaidan();
}
else
{
goto fanhui;
}
}
static void chaxun()//查询
{
Console.Clear();
Console.WriteLine("");
Console.WriteLine(" ++++++++++++++++++++图书信息查询+++++++++++++++++++");
Console.WriteLine("");
Console.WriteLine("请输入查询的条件 返回主菜单请按f");
Console.WriteLine("");
string i = Console.ReadLine();
if (i == "f")
{
zhucaidan();
}
}
这是已经给了的函数:
using System;
using System.Collections.Generic;
using System.Text;
using
namespace test
{
class Program
{
private static FileStream fs_OpenTxt;
static void Main(string[] args)
{
string str = "wewerwe oiiipi poipipi pipipi";
string[] str_Arry = str.Split(new char[] { ' ' });
Console.WriteLine(str);
foreach (string temp in str_Arry)
{
Console.WriteLine(temp);
}
//string[] str_Mystr = ReadTxt("temp.txt");
//InsertTxt("temp.txt", "9967");
//foreach(string temp in str_Mystr)
//{
// Console.WriteLine(temp);
//}
Console.ReadKey();
}
static void OpenTxt(string str_Path)
{
if (File.Exists(str_Path))
{
fs_OpenTxt = new FileStream(str_Path, FileMode.Open);
}
else
{
fs_OpenTxt = new FileStream(str_Path, FileMode.OpenOrCreate);
}
}
static string[] ReadTxt(string str_Path)
{
int int_Count = IOCount(str_Path);
OpenTxt(str_Path);
StreamReader sr_ReadInfo = new StreamReader(fs_OpenTxt);
string[] str_Arry = new string[int_Count];
for (int i = 0; i < int_Count; i++)
{
str_Arry[i] = sr_ReadInfo.ReadLine();
}
fs_OpenTxt.Close();
return str_Arry;
}
static int IOCount(string str_Path)
{
OpenTxt(str_Path);
int int_Count = 0;
using (StreamReader sr_temp = new StreamReader(fs_OpenTxt))
{
string str_Null = "";
while ((str_Null = sr_temp.ReadLine()) != null)
{
int_Count++;
}
}
fs_OpenTxt.Close();
return int_Count;
}
static void InsertTxt(string str_Path,string str_InsetTxt)
{
string[] str_Temp = ReadTxt(str_Path);
File.Delete(str_Path);
OpenTxt(str_Path);
using (StreamWriter sw_InsertTxt = new StreamWriter(fs_OpenTxt))
{
for (int i = 0; i < str_Temp.Length; i++)
{
sw_InsertTxt.WriteLine(str_Temp[i]);
}
sw_InsertTxt.WriteLine(str_InsetTxt);
}
fs_OpenTxt.Close();
}
}
}
我单独先做出来的查询:
class Program
{
struct book
{
public string mingcheng;
public string zuozhe;
public string chubanshe;
public string bianhao;
}
static void Main(string[] args) //主函数
{
book[] bo_Arry = new book[5];
bo_Arry = shu();
chaxun(bo_Arry);
Console.ReadKey();
}
static book[] shu()
{
book[] bo_Arry = new book[5];
for (int i = 0; i < 5;i++ )
{
bo_Arry[0].mingcheng = "梦里花落知多少";
bo_Arry[0].bianhao = "第00010号";
bo_Arry[0].zuozhe = "郭敬明";
bo_Arry[0].chubanshe = "山东出版社";
bo_Arry[1].mingcheng = "朝花夕拾";
bo_Arry[1].bianhao = "第00011号";
bo_Arry[1].zuozhe = "鲁迅";
bo_Arry[1].chubanshe = "北京出版社";
bo_Arry[2].mingcheng = "三重门";
bo_Arry[2].bianhao = "第00012号";
bo_Arry[2].zuozhe = "韩寒";
bo_Arry[2].chubanshe = "上海出版社";
bo_Arry[3].mingcheng = "那小子真帅";
bo_Arry[3].bianhao = "第00013号";
bo_Arry[3].zuozhe = "可爱淘";
bo_Arry[3].chubanshe = "江苏出版社";
bo_Arry[4].mingcheng = "猫";
bo_Arry[4].bianhao = "第00014号";
bo_Arry[4].zuozhe = "老舍";
bo_Arry[4].chubanshe = "大连出版社";
}
return bo_Arry;
}
static void chaxun(book[] bo_Temp)
{
string i = Console.ReadLine();
for (int q = 0; q < bo_Temp.Length; q++)
{
if (i == bo_Temp[q].mingcheng)
{
PrintAryy(bo_Temp[q]);
}
else if (i == bo_Temp[q].zuozhe)
{
PrintAryy(bo_Temp[q]);
}
else if (i == bo_Temp[q].chubanshe)
{
PrintAryy(bo_Temp[q]);
}
else if (i == bo_Temp[q].bianhao)
{
PrintAryy(bo_Temp[q]);
}
}
Console.WriteLine();
}
static void PrintAryy(book bo_Temp)
{
Console.WriteLine(bo_Temp.bianhao + " " + bo_Temp.mingcheng + " " + bo_Temp.zuozhe + " " + bo_Temp.chubanshe);
}
}
高手们呀````
