c# - Split string separated by multiple spaces, ignoring single spaces -

i need split string separated multiple spaces. example:

"aaaa aaa        bbbb bbb bbb        cccccccc" 

i want split these:

"aaaa aaa"    "bbbb bbb bbb" "cccccccc" 

i tried code:

value2 = system.text.regularexpressions.regex.split(stringvalue, @"\s+"); 

but not success, want split string multiple spaces, not single space.

+ means "one or more", single space qualify separator. if want require more once, use {m,n}:

value2 = system.text.regularexpressions.regex.split( stringvalue, @"\s{2,}"); 

the {m,n} expression requires expression prior match m n times, inclusive. 1 limit required. if upper limit missing, means "m or more repetitions".
