CString是个字符串数组，你SetAt的时候数组越界了。 当你第一次初始化m_ImageFold的时候，长度就固定了，你不能用超过字符串长度的索引来SetAt参考msdn： You can think of a CString object as an array of characters. The SetAt member function overwrites a single character specified by an index number.SetAt will not enlarge the string if the index exceeds the bounds of the existing string.取目录可以这样 CString ImageFileName = dlg.GetFileName(); CString ImagePathName = dlg.GetPathName(); CString ImageFolder = ImagePathName.Left(ImagePathName.Length() - ImageFileName.Length());网上抄的...那边百度回答你MSDN说明的也是我....咋地能有一个得分吧..哈哈
