  1.   

    你这个代码有点纠结了，我给你改了下
            private void button0_Click(object sender, EventArgs e)
            {
                textBox1.Text += button0.Text;
            }        //button1到button14的代码完全相同，这里省略了。。          private void button15_Click(object sender, EventArgs e)
            {
                string str = textBox1.Text.Trim();
                while (str.EndsWith("="))
                    str=str.Remove(str.Length - 1, 1);
                System.Text.RegularExpressions.Regex regex1 = new System.Text.RegularExpressions.Regex(@"^(\d+)\+(\d+)$");
                System.Text.RegularExpressions.Regex regex2 = new System.Text.RegularExpressions.Regex(@"^(\d+)\1(\d+)$");
                System.Text.RegularExpressions.Regex regex3 = new System.Text.RegularExpressions.Regex(@"^(\d+)\*(\d+)$");
                System.Text.RegularExpressions.Regex regex4 = new System.Text.RegularExpressions.Regex(@"^(\d+)\/(\d+)$");            System.Text.RegularExpressions.Match m;
                if ((m = regex1.Match(str)).Success)
                {
                    textBox1.Text = (int.Parse(m.Groups[1].Value) + int.Parse(m.Groups[2].Value)).ToString();
                }
                else if ((m = regex2.Match(str)).Success)
                {
                    textBox1.Text = (int.Parse(m.Groups[1].Value) - int.Parse(m.Groups[2].Value)).ToString();
                }
                else if ((m = regex3.Match(str)).Success)
                {
                    textBox1.Text = (int.Parse(m.Groups[1].Value) * int.Parse(m.Groups[2].Value)).ToString();
                }
                else if ((m = regex4.Match(str)).Success)
                {
                    textBox1.Text = (int.Parse(m.Groups[1].Value) / int.Parse(m.Groups[2].Value)).ToString();
                }
                else
                {
                    MessageBox.Show("格式错误,正确为:a+b;a-b;a*b;a/b");
                    textBox1.Text = "";
               }
            } 
      

  2.   

    System.Text.RegularExpressions.Regex regex2 = new System.Text.RegularExpressions.Regex(@"^(\d+)\1(\d+)$");
    改成----》》》
    System.Text.RegularExpressions.Regex regex2 = new System.Text.RegularExpressions.Regex(@"^(\d+)\-(\d+)$");
