如何用C#编写九九乘法表？？

Posted 2023-03-02

跪求各位编程高手帮忙了？发下源代码！！

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace _99Mul

class Program

static void Main(string[] args)

Console.WriteLine("九九乘法表：");
for (int i = 1; i <= 9; i++)//i是行数

for (int j = 1; j <= i; j++)//列数j

Console.Write("0*1=2 ",i,j,i*j);

Console.WriteLine();

Console.ReadLine();




控制台可以直接输出，我编的http://hi.baidu.com/%E6%AD%A5%E5%BF%B5%E5%B0%98/ihome/myblog 参考技术A 一个两重循环，你随便建一个工程，默认的窗体是Form1，在窗体的Paint事件里，写这样的代码
private void Form1_Paint(object sender, PaintEventArgs e)

for (int i = 9; i >= 1; i--)

for (int j = i; j >= 1; j--)

e.Graphics.DrawString(j.ToString() + "*" + i.ToString() + "=" + (i * j).ToString(), new Font("宋体", 12), new SolidBrush(Color.Black), new PointF(j * 100, i * 30));



运行后的效果就是九九乘法表 参考技术B using System;

class Test

static void Main()

int i,j;
for(i = 1; i <= 9; i++)

for(j = 1; j <=i; j++)

Console.Write("0*1=2,2 ",i, j , i * j);

Console.WriteLine();



本回答被提问者采纳 参考技术C foreach实现乘法表：
string chengfabiao = "";
int[] a = new int[10];
int[] b = new int[10];

for (int i = 0; i <= 9; i++)

a[i] = i;
b[i] = i;

foreach (int j in a)

foreach (int k in b)

if (j > 0 && k > 0 && j >= k)

chengfabiao += j.ToString() + "*" + k.ToString() + "=" + (j * k).ToString() + " ";


chengfabiao += "<br/>";


for实现乘法表：
string chengfabiao = "";

for (int i = 1; i < 10; i++)

for (int j = i; j < 10; j++)

chengfabiao += i + "*" + j + "=" + (i * j) + " ";

chengfabiao += "<br/>";
参考技术D using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1

class Program

static void Main(string[] args)

for (int i = 1; i <= 9; i++)//九行

for (int j = 1; j <= i; j++)//列


Console.Write("0*1=2 ",i,j,i*j);

Console.WriteLine(" ");
