当用户单击确认和查看按钮时，respactive(key,value) 对存储在哈希表中，当用户单击查看按钮时，特定列表项元素的颜色为红色，我想要的是 if (key,value)对是使用评论按钮添加的，如果用户单击确认按钮，我想更改它的值，简而言之，我存储的这个(键，值)对(问题，答案)所以如果用户不确定答案而不是他点击审查，稍后他应该能够更改其答案并标记为确认，以便此列表项元素颜色变为绿色，我该怎么做
private void AddtoHashTabl(string key, string value)
{
if (hashtable.ContainsKey(key))
{
}
else
{
hashtable.Add(key, value);
}
}
private void Confirm_Click(object sender, EventArgs e)
{
string Q = "";
string A = "";
listView1.Items[Convert.ToInt16(listView1.SelectedItems[0].SubItems[0].Text) - 1].BackColor = Color.Green;
var q = Convert.ToInt16(listView1.SelectedItems[0].Text);
var selectedQuestion = questions[q - 1];
Q = selectedQuestion.Id;
if (radioButton12.Checked == true)
A = "1";
else if (radioButton11.Checked == true)
A = "2";
if (radioButton10.Checked == true)
A = "3";
if (radioButton9.Checked == true)
A = "4";
AddtoHashTabl(Q, A);
}
private void Review_Click(object sender, EventArgs e)
{
string Q = "";
string A = "";
listView1.Items[Convert.ToInt16(listView1.SelectedItems[0].SubItems[0].Text) - 1].BackColor = Color.Red;
var q = Convert.ToInt16(listView1.SelectedItems[0].Text);
var selectedQuestion = questions[q - 1];
Q = selectedQuestion.Id;
if (radioButton12.Checked == true)
A = "1";
else if (radioButton11.Checked == true)
A = "2";
if (radioButton10.Checked == true)
A = "3";
if (radioButton9.Checked == true)
A = "4";
AddtoHashTabl(Q, A);
}
在此先感谢您的帮助
