在Visual C ++使用^运算符++ [英] Use of ^ operator in visual c++
问题描述
我做的Visual C ++编程,我创建了一个CLR控制台应用程序。我注意到字符串数组应该如String声明^,不是的String []。有什么用^吗?为什么它被用来代替[]?而就是这种替代仅限于CLR应用程序?
这里是code的线和错误:
I am doing Visual c++ programming, I have created a CLR console application. I have noticed that String arrays should be declared like String ^, not String[]. What is the use of ^? And why is it being used instead of []? And is this substitution limited only to CLR applications? Here is a line of the code and the error:
array<String[]>[] abc;
所产生的误差为
错误C2143:语法错误:缺少;前[
error C2143: syntax error : missing ';' before '['
错误C2146:语法错误:缺少;符前ABC
error C2146: syntax error : missing ';' before identifier 'abc'
eror C2065:'ABC':未声明的标识符
eror C2065: 'abc' : undeclared identifier
推荐答案
抑扬口音意味着该对象是一个托管指针,它会被垃圾收集器自动收集 - 你不需要含蓄地做到这一点。
请看看这篇文章了解数组用C如何工作++ / CLI。
The circumflex accent means that the object is a managed pointer,it'll be automatically collected by the Garbage Collector - you don't need to do this implicitly. Please take a look at this article to understand how arrays work in C++/CLI.
在您的情况:
array<String^> ^abc;
,是这次换人仅仅限于CLR应用程序?的
是
