c# - Multiple RegEx negation matching -

i have following regex patterns:

1. "[0-9]{4,5}\.fu|[0-9]{4,5}\.ng|[0-9]{4,5}\.sp|[0-9]{4,5}\.t|jgb[a-z][0-9]|jni[a-z][0-9]|jn4f[a-z][0-9]|jnm[a-z][0-9]|jti[a-z][0-9]|jtm[a-z][0-9]|niy[a-z][0-9]|ssi[a-z][0-9]|jni[a-z][0-9]-[a-z][0-9]|jti[a-z][0-9]-[a-z][0-9]" ===> matches 8411.t or jnid8
2. "[0-9]{4,5}\.hk|hsi[a-z][0-9]|hmh[a-z][0-9]|hcei[a-z][0-9]|hcei[a-z][0-9]-[a-z][0-9]" ==> matches 9345.hk or hceiu9-a9
3. ".*\.si|sfc[a-z][0-9]" ==> matches 8345.si or sfcx8

how can obtain regex negation of these patterns? want match strings match neither of these 3 patterns: e.g. want match 8411.abc, not of aforementioned strings (8411.t, hceiu-a9, 8345.si, etc.).

i've tried (just exclude 2 , 3 instance, doesn't work):

^(?!((.*\.si|sfc[a-z][0-9])|([0-9]{4,5}\.hk|hsi[a-z][0-9]|hmh[a-z][0-9]|hcei[a-z][0-9]|hcei[a-z][0-9]-[a-z][0-9])))  

the main idea here place patterns (?!.*<pattern>) negative lookaheads anchored @ start of string (^). difficulty here patterns contain unanchored alternations, , if not grouped, .* before patterns refer first alternative (i.e. subsequent alternatives negated @ start of string.

thus, pattern formula ^(?!.*(?:<pattern1>))(?!.*(?:<pattern2>))(?!.*(?:<pattern3>)). note .+ or .* @ end optional if need boolean result. note in last pattern, need remove .* in first alternative, won't make sense use .*.*.

use

^(?!.*(?:[0-9]{4,5}\.fu|[0-9]{4,5}\.ng|[0-9]{4,5}\.sp|[0-9]{4,5}\.t|jgb[a-z][0-9]|jni[a-z][0-9]|jn4f[a-z][0-9]|jnm[a-z][0-9]|jti[a-z][0-9]|jtm[a-z][0-9]|niy[a-z][0-9]|ssi[a-z][0-9]|jni[a-z][0-9]-[a-z][0-9]|jti[a-z][0-9]-[a-z][0-9]))(?!.*(?:[0-9]{4,5}\.hk|hsi[a-z][0-9]|hmh[a-z][0-9]|hcei[a-z][0-9]|hcei[a-z][0-9]-[a-z][0-9]))(?!.*(?:\.si|sfc[a-z][0-9])).+ 

see regex demo.

you may contract formula ^(?!.*(?:<pattern1>|<pattern2>|<pattern3>)):

^(?!.*(?:[0-9]{4,5}\.fu|[0-9]{4,5}\.ng|[0-9]{4,5}\.sp|[0-9]{4,5}\.t|jgb[a-z][0-9]|jni[a-z][0-9]|jn4f[a-z][0-9]|jnm[a-z][0-9]|jti[a-z][0-9]|jtm[a-z][0-9]|niy[a-z][0-9]|ssi[a-z][0-9]|jni[a-z][0-9]-[a-z][0-9]|jti[a-z][0-9]-[a-z][0-9]|[0-9]{4,5}\.hk|hsi[a-z][0-9]|hmh[a-z][0-9]|hcei[a-z][0-9]|hcei[a-z][0-9]-[a-z][0-9]|\.si|sfc[a-z][0-9])).+
