    }

    private void button1_Click(object sender, EventArgs e)
    {
        FileInfo file = new FileInfo(textBox1.Text);
        StreamReader stRead = file.OpenText();

<p class="indent">Mr. Cutler Figure 2.1 of the parallel plunges</p>

Answer 1

我认为你需要测试

FileInfo file = new FileInfo(textBox1.Text);
StreamReader stRead = file.OpenText();
while (!stRead.EndOfStream)
{
    string strTemp = stRead.ReadLine();
    for (int i = 1; i < MaxFigureCount; i++)
        strTemp = strTemp.replace("Figure "+i+" ", "Figure "+i+".x ");
    listBox1.Items.Add(strTemp);
}

你可以看到我不知道你的MaxFigureCount我也".x"因为我无法弄清楚你想要做什么。

我最后还有额外的空间，以确保我们不会错过2.1或1.2，如果它们已经存在。

Answer 2

使用String.Replace

while (!stRead.EndOfStream)
{
    string test = stRead.ReadLine();
    string correctString = test.Replace("Figure 1", " Figure 1.2");
    //Etc. etc.....
    listBox1.Items.Add(correctString);
}

Answer 3

尝试使用Regex.Replace：

listBox1.Items.Add(Regex.Replace(stRead.ReadLine(), @"\sFigure \d+.\d+\s", " Figure 1 "));

我做了一些测试，显然工作正常，但我不是正则表达式语法专家。
