findStr(strs,["exe","lib","dll","a"]))
bool findStr(string strIn,string[] strFind)

phobos 's string.d can add this some function to let the

Thank you.

std.algorithm.canFind will do what you want, including telling
you which of ["exe","lib","dll","a"] was found.
If you need to know where in strs it was found as well, you can
use std.algorithm.find
Sorry, 'std.algorithm.find' do this work:Finds an individual
element in an input range,and it's Parameters: InputRange
haystack The range searched in.
Element needle The element searched for.
But now I want to know in a string (like "hello.exe" or
"hello.a",or "hello.dll" or "hello.lib" ) whether contains any of
them: ["exe","dll","a","lib"].
My function 'findStr' works fine. If the string.d's function
'indexOfAny' do this work,it will happy.(but now 'IndexOfAny'
and 'indexOf' do the same work) .
Thank you.
