使用正则表达式搜索字符串 [英] Search Strings Using Regular Expressions

问题描述

嗨朋友们，



我有小问题，

Hi Friends ,

I Have Small Problem ,

string sample1 = "AK12-13/000000029024";
            string Patten1 = "^\\[A-Za-z]{2}-\\d{2}/\\d{12}$";
            System.Text.RegularExpressions.Match match1 = System.Text.RegularExpressions.Regex.Match(sample1, Patten1, System.Text.RegularExpressions.RegexOptions.IgnoreCase);
            if (!match1.Success)
            {
                MessageBox.Show("Please enter a valid  Patten.", "TEST", MessageBoxButtons.OK, MessageBoxIcon.Warning);

                return;
            }

但它不起作用，任何一个Plz帮助

Condisions：



•前两位必须是字母AK

•其次，第五个字符必须是 -
•第三，第8个字符必须是/

•最后在第8个位置之后的最后12个字符必须是数字。

But its not working , Any one Plz to Help
Condisions:

• The first two digits have to be Alphabets "AK"
• Secondly, the 5th character has to be a "-"
• Thirdly, the 8th character has to be a "/"
• Finally the last 12 characters after the 8th place onwards have to be numeric.

推荐答案

;
System.Text.RegularExpressions.Match match1 = System.Text.RegularExpressions.Regex.Match（sample1，Patten1，System.Text.RegularExpressions.RegexOptions。 IgnoreCase）;
if （！match1.Success）
{
MessageBox.Show（ 请输入有效的Patten。， TEST，MessageBoxButtons.OK，MessageBoxIcon 。警告）;

return ;
}

"; System.Text.RegularExpressions.Match match1 = System.Text.RegularExpressions.Regex.Match(sample1, Patten1, System.Text.RegularExpressions.RegexOptions.IgnoreCase); if (!match1.Success) { MessageBox.Show("Please enter a valid Patten.", "TEST", MessageBoxButtons.OK, MessageBoxIcon.Warning); return; }

试试这个 Patten1 变量：

Hi,

Try this as Patten1 variable:

string Patten1 = "^AK.{2}-.{2}/[0-9]{12}

;

希望这会有所帮助。
