regex - Regular expression for street address? -


this question has answer here:

i need regular expression street address example: 

test 123 - valid 123 test -not valid

so need letters(required) space , number(required) tried without success

@"^[a-za-z ][0-9 ]"

you need include quantifiers, anchors.

@"^[a-za-z]+ [0-9]+$"

+ repeats previous token 1 or more times.

you may use if space optional.

@"^[a-za-z]+ ?[0-9]+$"
