//Recapitalize if necessary .
if(bCaps)

}
}
please remove this error onlyy,,................ send me d corrected 1 , after removng error ...
ohk , pls do that in free time , if u will get time.
推荐答案
字符串，我假设您想在每个空格字符处分割字符串，因此您需要执行以下操作:
Since you apparanetly want the words in the string, I''m assuming you want to split the string at every space character, so you need to do this:
arrWords = mstrText.Split(" ");
