正则表达式的验证表达式 [英] Validation Expression for Regex

问题描述

我想知道正则表达式验证表达式，该表达式仅接受TextBox的小数和整数.

例如:

它应该只接受此值

1
2
3
1.22
2.33
42344.54
43434.00

我已经给出了验证表达式/^(\d+(?:[\.]\d{2})?)$/，但是它仅接受整数，因此不允许我输入十进制值.谁能帮我解决这个问题.

Hi,

I want to know the Regex Validation Expression for accepting only Decimals and Integers for the TextBox.

Eg:

It should accept only this values

1.22
2.33
42344.54
43434.00

I have given the Validation Expression /^(\d+(?:[\.]\d{2})?)$/ but it is accepting only integers it is not allowing me to enter decimal values. Can any one help me to solve this problem.

Thanks in Advance

您可以在此处使用此代码:

You could use this code here:

Dim Real As String = "(?<!([E][+-][0-9]+))([-]?\d+\.?\d*([E][+-]" & _
         "[0-9]+)?(?!([i0-9.E]))|[-]?\d*\.?\d+([E][+-][0-9]+)?)(?![i0-9.E])"
