具体实现如下

if (mandName == "delete")//判断操作

{int index1 = Convert.ToInt32(mandArgument); string del =

this.GridView1.Rows[index1].Cells[0].Text.ToString();

myconn.Open();

SqlCommand cmd = new SqlCommand("select 使用 from

T_SingleChoice where 题目ID='" + del + "' ", myconn);

SqlDataReader dr = cmd.ExecuteReader(); int i = 0;

while (dr.Read()) if (i < GridView1.Rows.Count && dr[0].ToString() == "1") {

Response.Redirect("ManageSingleChoice.aspx"); }i++; dr.Close();

string del1 = "delete from T_SingleChoice where 题目ID='" + del + "'";//删除字符串

SqlCommand del2 = new SqlCommand(del1, myconn); GridView1dataBind();//数据再次绑定 shuaxin();//页面刷新 刷新页面的函数

protected void shuaxin() {

SqlCommand cmd = new SqlCommand("select 使用,题干 from T_SingleChoice where 科目ID='" + DropDownList1.SelectedValue + "'", Con1); SqlDataReader dr = cmd.ExecuteReader(); CheckBox checkbox1;

while (dr.Read()){

if (i < GridView1.Rows.Count && dr[0].ToString() == "1"){ checkbox1 =(CheckBox)GridView1.Rows[i].

FindControl("CheckBox1");checkbox1.Checked = true;} i++;}

}

4 添加题目

题目的添加必须要完整，否则就不能做为一道题目来使用，即作为单选题，所有选项和题干都不能为空，正确答案和难度系数也不能为空。一旦题目不完整，

就不能添加。如下所示：

信息填写完整后，添加成功结果如下

实现过程如下

protected void Button1_Click(object sender, EventArgs e) {

string answer=null;string level = null; for(int i=1;i<=3;i++){
