C# 使用NFA数据生成DFA文件数据 - VS软件实现

下面是生成DFA数据的代码实现：

private void button7_Click(object sender, EventArgs e) { // 获取NFA数据 List<string[]> nfaData = new List<string[]>(); foreach (ListViewItem item in listView1.Items) { string[] data = new string[3]; data[0] = item.SubItems[0].Text; data[1] = item.SubItems[1].Text; data[2] = item.SubItems[2].Text; nfaData.Add(data); }

// 生成DFA数据
List<string[]> dfaData = new List<string[]>();
List<string> stateSet = new List<string>();
List<string> symbolSet = new List<string>();
List<string> endStateSet = new List<string>();

// 添加初始状态
string[] startState = new string[] { startSymbol };
stateSet.Add(startSymbol);
dfaData.Add(startState);

// 遍历状态集
for (int i = 0; i < stateSet.Count; i++)
{
    string state = stateSet[i];

    // 遍历符号集
    foreach (string symbol in symbolSet)
    {
        List<string> nextStateSet = new List<string>();

        // 遍历NFA数据，获取到达状态集合
        foreach (string[] data in nfaData)
        {
            if (data[0] == state && data[1] == symbol)
            {
                nextStateSet.Add(data[2]);
            }
        }

        // 判断是否为新状态
        string nextState = string.Join(',', nextStateSet.ToArray());
        if (!stateSet.Contains(nextState))
        {
            stateSet.Add(nextState);
            string[] dfaState = new string[] { nextState };
            dfaData.Add(dfaState);
        }

        // 添加转移
        string[] dfaTransition = new string[] { state, symbol, nextState };
        dfaData.Add(dfaTransition);
    }

    // 判断是否为终止状态
    if (state.Split(',').Intersect(endSymbol.Split(',')).Any())
    {
        endStateSet.Add(state);
    }
}

// 显示DFA数据
listView2.Items.Clear();
foreach (string[] data in dfaData)
{
    ListViewItem item = new ListViewItem(data);
    listView2.Items.Add(item);
}

}
