解析字体字符串时索引超出数组错误的范围?

我一直在#574行得到“索引超出数组范围”的错误:

label.Font = new Font(fontNameFields [0],Single.Parse(fontNameFields [1]));

...我正在解析的以下文本文件包含以下确切信息:

Label
"hi tyler"
23, 76
Arial,12.5

...我可以成功解析所有其他信息(只是不是最后一行),我的代码是:

MatchCollection lines = Regex.Matches(File.ReadAllText(Path), @"(.+?)\r\n""([^""]+)""\r\n(\d+), (\d+)");
foreach (Match match in lines)
{
    string control = match.Groups[1].Value;
    string text = match.Groups[2].Value;
    int x = Int32.Parse(match.Groups[3].Value);
    int y = Int32.Parse(match.Groups[4].Value);
    String cfont = match.Groups[5].Value;
    string color = match.Groups[6].Value;

    Console.WriteLine("{0}, \"{1}\", {2}, {3}, {4}, {5}", control, text, x, y, cfont, color);



    switch (control)
    {
        case "Label":
            Label label = new Label();    

            label.Text = text;

            label.AutoSize = true;
            label.IsAccessible = true;

            label.MouseClick += new MouseEventHandler(label_MouseClick);
            label.MouseDoubleClick += new MouseEventHandler(label_MouseDoubleClick);
            label.MouseDown += new MouseEventHandler(label_MouseDown);
            label.MouseMove += new MouseEventHandler(label_MouseMove);
            label.MouseUp += new MouseEventHandler(label_MouseUp);

            label.Location = new Point(x, y);
            canvas.Controls.Add(label);

                            String fontName = cfont;
    String[] fontNameFields = fontName.Split(',');


    label.Font = new Font(fontNameFields[0], Single.Parse(fontNameFields[1]));

...我认为正则表达式中可能存在一些错误,它会获得字体...我不知道,但它只是不起作用,有人可以帮忙吗?

尝试

@"(.+?)\r\n""([^""]+)""\r\n(\d+), (\d+)\r\n(\w+,\d+\.?\d)"

它类似于slashmais解决方案,在字体及其大小方面只有一点限制性,并且更接近你原来的,我喜欢它,因为块更清晰可见。
