推荐答案

请参阅我对该问题的评论。我会质疑你是否需要使用修复;这是第一个要考虑的事情。



但是如果你真的需要，你总是可以逐个字符地复制循环中的字符串。此外，请参阅： http://msdn.microsoft .com / zh-CN / library / system.string.copyto％28v = vs.110％29.aspx [ ^ ]。

Please see my comment to the question. I would question if you need to use fixed at all; this is the first thing to think about.

But if you really need to, you can always copy a string in the loop character by character. Besides, please see: http://msdn.microsoft.com/en-us/library/system.string.copyto%28v=vs.110%29.aspx[^].
