求高手帮忙看下这个 正则表达式

Question

字符长度是固定，那这段要怎么改呢，对正则不是很熟悉，这代码也参考别人写出来的
Regex reg = new Regex(@"(?is)[\d]{4}_[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}");

字符长度是固定，那这段要怎么改呢，对正则不是很熟悉，这代码也参考别人写出来的
Regex reg = new Regex(@"(?is)[\d]{4}_[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}"); 我对正则也不熟，你直接截取字符串吧用subString();

Answer 2

var str = "B_F_SENSUS_2G_5322_56.81.13.51.01.28";
Regex r = new Regex(@"(?is)[\d]{4}_[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}", RegexOptions.IgnoreCase);
Match m = r.Match(str);
while (m.Success)
{
var test = m.Groups[0].Value.Replace("_", "").Replace(".", "");
//输出5322568113510128
MessageBox.Show(test);
}
已测试。

Answer 3

你这正则跟我这代码差不多啊，你是怎么把2D这2字符给去除的呢？
能说下嘛？小弟对正则不是很懂
这是我代码 if (fileName.Contains("BTG"))
                {
                    for (int i = 0; i < listBox4.Items.Count; i++)
                    {
                     
                        Regex reg = new Regex(@"(?is)[\d]{4}_[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}");                   
                        MatchCollection mc = reg.Matches(this.listBox4.Items[i].ToString());
                        foreach (Match m in mc)
                        {
                          this.listBox2.Items.Add(Regex.Replace(this.listBox4.Items[i].ToString(), @"\D", string.Empty));                        }
                    } 
                }

Answer 4

   if (fileName.Contains("BTG"))
                {
                    for (int i = 0; i < listBox4.Items.Count; i++)
                    {
                     
                        Regex reg = new Regex(@"(?is)[\d]{4}_[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}");
                        MatchCollection mc = reg.Matches(this.listBox4.Items[i].ToString());
                        foreach (Match m in mc)
                        {
                          this.listBox2.Items.Add(Regex.Replace(this.listBox4.Items[i].ToString(), @"\D", string.Empty));                        }
                    } 
                }我这段代码是什么问题呢？ 取出来后怎么是2533..... 多了个2呢？

 if (fileName.Contains("BTG"))
{
for (int i = 0; i < listBox4.Items.Count; i++)
{
Regex reg = new Regex(@"(?is)[\d]{4}_[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}.[\d]{2}", RegexOptions.IgnoreCase);
Match mc = r.Match(this.listBox4.Items[i].ToString());
foreach (Match m in mc)
{
this.listBox2.Items.Add(m.Groups[0].Value.Replace("_", "").Replace(".", ""))); }
}
}
