解析字体的信息，并将其转换为System.Drawing.Font(Parsing font inf

我有一个包含这样的字体信息的文本文件：

宋体，12.5

......我需要阅读这些信息到label.Font是这样的：

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

...但我总是得到以下错误：

指数数组的边界之外。

可有人请帮助我？

感谢杰森。

代码我有：

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


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

Answer 1:

我怀疑你正在运行到不包含逗号线。您的样本数据好工作：

using System;

class Test
{
    static void Main(string[] args)
    {
        String fontName = "Arial, 12.5";
        String[] fontNameFields = fontName.Split(',');
        String name = fontNameFields[0];
        float size = float.Parse(fontNameFields[1]);
        Console.WriteLine("{0}: {1}", name, size);
    }
}

Answer 2:

难道是你的格式包含了一个奇怪的逗号，或者根本就没有？

也可能你在标签上提供的代码，就好像它是一个System.Web.UI.WebControls然后字体并没有一个二传手。

飞碟双向的代码上面给定的输入工作正常。你的问题不在于此。

Answer 3:

乍一看代码看起来OK。

你有没有检查了fontName是你所期望它是（即“宋体，12.5”），什么fontNameFields调用后包含fontName.Split ？

fontNameFields[0] -> "Arial"
fontNameFields[1] -> "12.5"

在没有看到实际值我不希望暗示任何东西。

编辑

从你更新的代码我建议，这是你的正则表达式多数民众赞成失败。尝试打印出来的内容match.Groups阵列，以检查是否已正确解析输入。
