[英]Index out of bounds of array error when parsing font string?
我不断在第574行收到“索引超出数组范围”错误,该错误是:
label.Font = new Font(fontNameFields [0],Single.Parse(fontNameFields [1]));
...我正在解析的以下文本文件包含此确切信息:
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),我拥有的代码是:
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]));
...我认为获取字体内容的正则表达式可能存在问题...我不知道,但这只是行不通,有人可以帮忙吗?
有关此问题的历史记录,请参阅: 解析字体信息并将其转换为System.Drawing.Font
尝试
@"(.+?)\r\n""([^""]+)""\r\n(\d+), (\d+)\r\n(\w+,\d+\.?\d)"
它类似于slashmais解决方案,只是在字体及其大小方面有更多限制,并且更接近于您的原始字体,我喜欢它,因为这些块更清晰可见。
