lua字符串分割 string.split实现

function Split(szFullString, szSeparator)
local nFindStartIndex = 1
local nSplitIndex = 1
local nSplitArray = {}
while true do
   local nFindLastIndex = string.find(szFullString, szSeparator, nFindStartIndex)

    nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, string.len(szFullString))
    break
   end
   nSplitArray[nSplitIndex] = string.sub(szFullString, nFindStartIndex, nFindLastIndex - 1)
   nFindStartIndex = nFindLastIndex + string.len(szSeparator)
   nSplitIndex = nSplitIndex + 1
end
return nSplitArray
