C#设计一个简单的计算器,实现两个数的加,减,乘,除,求幂等计算,运行效果如下图所示:

1.题目要求如下:

C#设计一个简单的计算器,实现两个数的加,减,乘,除,求幂等计算,运行效果如下图所示:

 2.这边需要用到的是VS2019下的C#Windows窗体

3.来吧,展示:

using System.Windows.Forms;

                i2 = (int)Convert.ToInt64(s2);
                double s3 = Math.Pow(i1, i2);
                string s4 = Convert.ToString(s3);
                MessageBox.Show(s4);
            }

        }
        private void button5_Click(object sender, EventArgs e)
        {
            //归零
            textBox1.Text = string.Empty;
            textBox2.Text = string.Empty;
        }
    }
}

这个有140多行代码稍微有点长,有待改善

4.来看看运行结果:ctrl+f5

 这边自由发挥加上了弹窗提示的效果

 这边演示的为9的9次方结果

希望能帮到大家,问你们要一个赞,你们会给吗,谢谢大家
