本文介绍了字符串问题 - 请帮助的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我有一点问题就是用一些，来连接一个字符串。这是我的代码： Dim mystring as string ="" for i = 1到3 mystring = mystring& "，" &安培; Otherstring next i 我正在得到这样的结果 " a，b，c， 和数字我得到这个结果 "，1,2,3" 我怎样才能做到a，b，c和1,2,3 ？ 谢谢。 T :-) 解决方案 也许是这样的： dim mystring as string ="" for i = 1 to 3 如果len（mystring）= 0那么 mystring = Cstr（i） else mystring = mystring& ， &安培; CStr（i） 结束如果 下一个我 这将给你1,2,3 希望这会有所帮助..

Thanks. T :-) Here''s one way. Note that the function doesn''t do any checking or trimming,so it will happily append empty strings or strings containing nothing butwhite space. Also note that if you''re going to do very many of these stringconcatenations, you should use a StringBuilder instead.
