Question

可能重复：
Regex matching too much

测试字符串：

[TA:1010100][FN:AmplifySignal][IP:(Factor|System.Double|"1.5")(Source|System.String|"Sourcetest")(Destination|System.String|"DestTest")]

此字符串的一般格式分为3组：

group1 =＆gt; “[TA：”+ 1或0重复+“]”
group2 =＆gt; “[FN：”+ A-Z或a-z +“]”
group3 =＆gt; “[IP：”+（。*）+“]”

我已经尝试了许多正则表达式的变体，可以让整个测试字符串返回或没有...我可以弄清楚如何实际分割它并返回子串。

尝试过的模式包括但不限于：

@"^.*$"
@"^[.*].*$"
@"^(\[.*\])(.*)$"
@"^(\[.*\])(\[.*\])(\[.*\])$"
@"^(\[TA{[10],}\])(\[.*\])(\[.*\])$" ......等等。

调用代码：

BindingList<Tuple<bool[], IFactory>> Recipe = new BindingList<Tuple<bool[], IFactory>>();

var amp = new Factory.AmplifySignal();
amp.Destination = "DestTest";
amp.Source = "Sourcetest";
amp.Factor = 1.5;
bool[] Ts = new bool[] { true, false, true, false, true, false, false };

var CI = new CompactInstruction(Ts, amp.GetFactoryKey(), amp.GetProperties());

string TestString = CI.ToString();
Console.WriteLine(TestString);

string pattern = @"^(\[.*\])?"; //Have been adjusting in debug mode
while (true)
{
    try
    {
        Match Result = Regex.Match(TestString, pattern, RegexOptions.IgnoreCase);
        if (Result.Success)
        {
            for (int i = 0; i < Result.Groups.Count; i++)
            {
                Console.WriteLine("G{0} - \r\n\t{1}", i, Result.Groups[i]);                            
            }
        }
    }
    catch { }
}

测试

[TA:1010100][FN:AmplifySignal][IP:(Factor|System.Double|"1.5")(Source|System.String|"Sourcetest")(Destination|System.String|"DestTest")]

图案

string pattern = @"^(\[.*?\])?(\[.*?\])?(\[.*?\])?$";

输出：

G0 - 
    [TA:1010100][FN:AmplifySignal][IP:(Factor|System.Double|"1.5")(Source|System.String|"Sourcetest")(Destination|System.String|"DestTest")]
G1 - 
    [TA:1010100]
G2 - 
    [FN:AmplifySignal]
G3 - 
    [IP:(Factor|System.Double|"1.5")(Source|System.String|"Sourcetest")(Destination|System.String|"DestTest")]

从Regex返回Group，而不是整行
