如何從C＃中的給定字符串中檢索特定文本

Question

我想從以下字符串中檢索特定文本。我在字符串中有一些粗體標簽和段落標簽。我只想檢索在粗體標簽（ ... ）下的文本。這是我的要求。我想存儲在字符串數組中檢索到的值。

SampleText<b>Billgates</b><p>This is Para</p><b>SteveJobs</b>ThisisEnd

需要在c＃.Output中實現此目標，如下所示。

str[0] = Billgates
str[1] = SteveJobs

Answer 1

您可以嘗試通過正則表達式進行解析：

Regex expression = new Regex(@"\<b\>(.*?)\<b\>"); //This matches anything between <b> and </b>

foreach (Match match in expression.Matches(code)) //Code being the string that contains '...<b>BillGates</b>...<b>etc</b>...'
{
    string value = match.Groups[1].Value;
    //And from here do whatever you like with 'value'
}

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] strArray = new string[50];
            string str = "SampleText<b>Billgates</b><p>This is Para</p><b>SteveJobs</b>ThisisEnd";

            Regex expression = new Regex(@"\<b\>(.*?)\</b\>");

            for (int i = 0; i < expression.Matches(str).Count; ++i)
            {
                string value = expression.Matches(str)[i].ToString();

                value = value.Replace("<b>", "");
                value = value.Replace("</b>", "");
                strArray[i] = value;
            }

            Console.WriteLine(strArray[0]);
            Console.WriteLine(strArray[1]);

            Console.ReadLine();
        }
    }
}
