here arrmenuid showing null values.

if 1 have solution, please let me know.

try changing

data: "arrmenuid"+ jsarraymenuid, 

to

data: {arrmenuid : jsarraymenuid.join()}  

and changing

public httpresponsemessage deleteallmenu(array arrmenuid) 

to

public httpresponsemessage deleteallmenu(string arrmenuid) 

i don't think javascript array translate c# array , changing instead passing string. once have comma delimited string can make array in c#
