急！！C# 用正则表达式验证 MAC地址（在线等）

Question

 string s = @"^([0-9a-fA-F]{2})(([/\s:-][0-9a-fA-F]{2}){5})$";
 Regex r = new Regex(s);
 MatchCollection oCollection = r.Matches(textBox3.Text.Trim());
if (oCollection.Count>0)
            {
                MessageBox.Show("MAC地址格式正确！");
            }

Answer 1

string s = @"^([0-9a-fA-F]{2})(([/\s:-][0-9a-fA-F]{2}){5})$";Regex r = new Regex(s, RegexOptions.IgnoreCase);Match m = r.Match(textBox3.Text.Trim());
if (m.Success)
  {
  MessageBox.Show("MAC地址格式正确！");
  }

Answer 2

[A-F\d]{2}:[A-F\d]{2}:[A-F\d]{2}:[A-F\d]{2}:[A-F\d]{2}:[A-F\d]{2}

Answer 3

MAC地址 正则表达式  
 
^([0-9a-fA-F]{2})(([/\s:-][0-9a-fA-F]{2}){5})$   
Mac地址以空格,"-",":"分开  ^([0-9a-fA-F]{2})(([0-9a-fA-F]{2}){5})$   中间没有任何符号  

Answer 4

Regex.IsMatch("00-1D-60-BB-70-E4",@"^([0-9a-fA-F]{2})(([/\s:-][0-9a-fA-F]{2}){5})$")
//没问题啊？怎么回事？

Answer 5

private void button1_Click(object sender, EventArgs e)
{
    string yourMac = "00-1D-60-BB-70-E4";
    if (Regex.IsMatch(yourMac, @"(?in)([\da-f]{2}-?){6}"))
    {
        MessageBox.Show("正确");
    }
    else
    {
        MessageBox.Show("错误");
    }
}

Answer 6

优化一下
private void button1_Click(object sender, EventArgs e)
{
    string yourMac = "00-1D-60-BB-70-E4";
    if (Regex.IsMatch(yourMac, @"^(?in)([\da-f]{2}(-|$)){6}"))
    {
        MessageBox.Show("正确");
    }
    else
    {
        MessageBox.Show("错误");
    }
}

Answer 7

可能会有-结尾的错误，再优化一次……
private void button1_Click(object sender, EventArgs e)
{
    string yourMac = "00-1D-60-BB-70-E4";
    if (Regex.IsMatch(yourMac, @"^(?in)([\da-f]{2}(-|$)){6}$"))
    {
        MessageBox.Show("正确");
    }
    else
    {
        MessageBox.Show("错误");
    }
}

Answer 8

不好意思，Regex.IsMatch  无论传入什么，都是不匹配

Answer 9

是不是有换行最后？
(?isn)([\da-f]{2}(-|\s*$)){6}\s*$
这样试试，
或是
if(Regex.IsMatch(textbox3.Text.Trim("\r\n".ToArray()),@"00-1D-60-BB-70-E4"))

Answer 10

if(Regex.IsMatch(textbox3.Text.Trim("\r\n".ToArray()),@"^(?in)([\da-f]{2}(-|$)){6}$"))
