2、ay.Text = 良好; break; case 7: lblDisplay.Text = 中等; break; case 6: lblDisplay.Text = 及格; break; default: lblDisplay.Text = 不及格; break; 2.在Web窗体中输出九九乘法表（1）登录事件protected void Page_Load(object sender, EventArgs e) for (int i = 1; i = 9; i+) for (int j = 1; j = i; j+) Response.Write(i.ToString() + x + j.
3、ToString() + = + (i * j).ToString(); Response.Write( ); Response.Write(); 3.输入一组以空格间隔的共10个以内的整数，输出该组整数的降序排列（1）控件设置 （2）单击事件protected void btnSubmit_Click(object sender, EventArgs e) string sInput = txtInput.Text.Trim() + ; int j = 0; int aInput = new int10; string temp = 0; for (int i = 0;
4、i = sInput.Length - 1; i+) if (sInput.Substring(i, 1) != ) temp += sInput.Substring(i, 1); else aInputj = int.Parse(temp); j+; temp = 0; Array.Sort(aInput); Array.Reverse(aInput); foreach (int i in aInput) if (i != 0) Response.Write(i+ ); 4.计算两个数的商（1）控件设置 （2）单击事件 protected void btnSubmit_
5、Click(object sender, EventArgs e) try float divsor = float.Parse(txtDivsor.Text); float dividend = float.Parse(txtDividend.Text); Response.Write(商为： + divsor / dividend); catch (Exception ee) Response.Write(请输入正确的数字！); 5.设计并实现一个用户信息类UserInfopublic class UserInfo private string _Name; private DateTim
6、e _Birthday; public string Name get return _Name; set _Name = value; public DateTime Birthday get return _Birthday; set _Birthday = value; public UserInfo(string name,DateTime birthday) this._Name = name; this._Birthday = birthday; public string DecideAge() if (DateTime.Now.Year - _Birthday.Year 18) return this._Name + ，您还没长大呢？; else return this._Name + ，您是成人了！; 6.在We
