I have this regex I built and tested in regex buddy.
"_ [ 0-9]{10}+ {1}+[ 0-9]{10}+ {2}+[ 0-9]{6}+ {2}[ 0-9]{2}"
When I use this in .Net C#
I receive the exception
"parsing \"_ [ 0-9]{10}+ +[ 0-9]{10}+ +[ 0-9]{6}+ [ 0-9]{2}\" - Nested quantifier +."
What does this error mean? Apparently .net doesn't like the expression.
Here is the regex buddy so u can understand my intention with the regex...
_ [ 0-9]{10}+ {1}+[ 0-9]{10}+ {2}+[ 0-9]{6}+ {2}[ 0-9]{2}
Match the characters "_ " literally «_ »
Match a single character present in the list below «[ 0-9]{10}+»
Exactly 10 times «{10}+»
The character " " « »
A character in the range between "0" and "9" «0-9»
Match the character " " literally « {1}+»
Exactly 1 times «{1}+»
Match a single character present in the list below «[ 0-9]{10}+»
Exactly 10 times «{10}+»
The character " " « »
A character in the range between "0" and "9" «0-9»
Match the character " " literally « {2}+»
Exactly 2 times «{2}+»
Match a single character present in the list below «[ 0-9]{6}+»
Exactly 6 times «{6}+»
The character " " « »
A character in the range between "0" and "9" «0-9»
Match the character " " literally « {2}»
Exactly 2 times «{2}»
Match a single character present in the list below «[ 0-9]{2}»
Exactly 2 times «{2}»
The character " " « »
A character in the range between "0" and "9" «0-9»
In short...
What is a Nested quantifier?
.NET is complaining about the +
after the {n}
style quantifier as it doesn't make any sense. {n}
means match exactly n of a given group. +
means match one or more of a given group. Remove the +
's and it'll compile fine.
"_ [ 0-9]{10} {1}[ 0-9]{10} {2}[ 0-9]{6} {2}[ 0-9]{2}"
