[英]Regex to allow numeric values between[1-100] and a percentage symbol
I want a regex to allow numeric values between 1 to 100 and one percentage symbol 我希望正则表达式允许1到100之间的数值和一个百分比符号
Valid samples: 0%, 100%, 100, 0, 65% 有效样本:0%,100%,100、0、65%
Invalid samples: 101, 101%, 100.1, 65.6%, 65.6 无效样本:101、101%,100.1、65.6%,65.6
Any help is appreciated 任何帮助表示赞赏
i dont speak regex but you saied any help would be appreciated so here i go: 我不会讲正则表达式,但是您说任何帮助将不胜感激,所以我在这里:
bool Verify(string input)
{
input = input.Replace("%", ""); // if it contains % remove it
int value;
if (Int32.TryParse(input, out value)) //if the input can be converted into a number
{
if (value > 1 && value < 100) //and the value is in range
{
return true; //return true to confirm it
}
}
return false; //in any other case return false
}
Try this: 尝试这个:
^(0*100{1,1}\.?((?<=\.)0*)?%$)|(^0*[1-9]\d{0,1}\.?((?<=\.)\d*)?%)$
It will allow 65%
and 100%
and discard 65
and 100.1%
它将允许
65%
和100%
并丢弃65
和100.1%
Matches a percentage between 0 and 100 (inclusive). 匹配0到100(含)之间的百分比。 Accepts up to 2 decimal places.
最多接受2个小数位。 ex: 0% , 100% , .17%
例如:0%,100%、. 17%
^( 100(?:\.0{1,2})? | 0*?\.\d{1,2} | \d{1,2}(?:\.\d{1,2})? )% $
