打印处理文件，后面跟着id

您的代码中缺少一对花括号。第一个foreach需要花括号来封装后面的所有代码。如果没有它，它只是抓取下一个语句并对行中的每个元素重复它。这就是为什么您得到的每一行都以"Processing"开头，后面跟着您的ID的两个匹配项。试试这个:

private void button1_Click(object sender, EventArgs e)
{
        string[] lines = value.Split(Environment.NewLine.ToCharArray()); 
        foreach (string l in lines)
        {
            if (l.IndexOf("Processing")==0)
            {
               textBox4.Text = textBox4.Text + l + Environment.NewLine;
            }
            MatchCollection matches2 = Regex.Matches(l, "'"([^'"]*)'"");
            foreach (Match match2 in matches2)
            {
                foreach (Capture capture2 in match2.Captures)
                {              
                    textBox4.Text = textBox4.Text + Environment.NewLine + capture2.Value;   
                }
            }
        }
    }

所以在这个例子中，我添加了我提到的花括号，我也去掉了value，而是告诉正则表达式搜索当前行。如果您每次都搜索value，那么最终得到的ID重复次数将远远超过您想要的输出。
