VS使用C#语言现在需要补充代码private void button7_Clickobject sender EventArgs e使用子集构造算法使得在lisview2中显示起始状态、接受符号、到达状态三列并在label5中显示初始状态集label7中显示终止状态集private void button3_Clickobject sender EventArgs e

private void button7_Click(object sender, EventArgs e) { //获取初始状态集 string[] startStates = startSymbol.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries); label5.Text = "初始状态集: " + startSymbol;

//获取终止状态集
string[] endStates = endSymbol.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);
label7.Text = "终止状态集: " + endSymbol;

//将起始状态、接受符号、到达状态添加到lisview2中
listView2.Columns.Add("起始状态");
listView2.Columns.Add("接受符号");
listView2.Columns.Add("到达状态");
listView2.View = View.Details;

foreach (string state in startStates)
{
    foreach (string symbol in symbolSet)
    {
        //获取到达状态
        string nextState = GetNextState(state, symbol);

        //添加到lisview2中
        ListViewItem item = new ListViewItem(state);
        item.SubItems.Add(symbol);
        item.SubItems.Add(nextState);
        listView2.Items.Add(item);
    }
}

}

//获取到达状态 private string GetNextState(string startState, string inputSymbol) { string nextState = ""; for (int i = 0; i < lines.Length; i++) { string[] tokens = lines[i].Split(new char[] { '\t' }, StringSplitOptions.RemoveEmptyEntries); if (tokens[0] == startState && tokens[1] == inputSymbol) { nextState += tokens[2] + ","; } } return nextState.TrimEnd(',');
