C++ TR1 regex_是否在VS2010中替换为wstring？ #包括 #包括 #包括 #包括 #包括 使用名称空间std； int main（） { 常数wstr（L“）； 静态常数wregex wr（wstr）； W字符串行（L“随机文本”）； wstring line2（L“）； wcout

部分答案：

您应该这样使用

regex\u repalce

wcout抱歉，问题是什么？sry，我试图编译它，但它从“const std:：tr1:：wregex”返回了关于模板“const std:：tr1:：basic_regex&”的错误，所以问题是-如何使它工作，使用这些字符串，并正确显示结果，我已经尝试了regex_替换（line，wr，line2），没有-它会返回一些随机信息，如“00423DA4”，你能复制错误吗？只是简单地说一些关于它的一般性信息对你没有帮助。在问题中添加了em是的，我发现函数中的locale出现了一些语法错误，我用它来填充列表1，解决了这个问题。
