简单的整数定期EX pression [英] Simple integer regular expression
问题描述
我 ValidationRegularEx pression =[0-9]只允许单个字符。我如何使它允许之间（包含），1和7位数？我试图 [0-9] {1-7} ，但没有奏效。
I have ValidationRegularExpression="[0-9]" which only allows a single character. How do I make it allow between (and including) 1 and 7 digits? I tried [0-9]{1-7} but it didn't work.
推荐答案
您得到了语法正确的差不多： [0-9] {1,7}
You got the syntax almost correct: [0-9]{1,7}.
您可以让您的解决方案有点更优雅（文化敏感），用 [0-9] 与通用字符组十进制数字： \\ D （记住，其它语言可能比0-9使用不同的字符位数）。
You can make your solution a bit more elegant (and culture-sensitive) by replacing [0-9] with the generic character group "decimal digit": \d (remember that other languages might use different characters for digits than 0-9).
