Beta 2：自动处理不作为？ [英] Beta 2: Automatic Dispose inaction?

问题描述

您好，


由于FileStream类中缺少复制构造函数，以下内容无法编译：


FileInfo ^ fi = ...;

FileStream fs = fi-> OpenRead（）;


编译器是Beta 2.是否支持？计划得到支持吗？

解决方案

你好，

以下内容由于FileStream类中缺少复制构造函数而无法编译：

FileInfo ^ fi = ...;
FileStream fs = fi-> OpenRead（）;

FileStream ^ fs = fi-> OpenRead（）;


-cd

你好，

以下不做由于在FileStream类中缺少复制构造函数而编译：

FileInfo ^ fi = ...;
FileStream fs = fi-> OpenRead（）;

FileStream ^ fs = fi-> OpenRead（）;

此模式仅适用于C ++ / CLI实现的类，FCL用
$ b $编写b C＃和他们的类不能堆栈分配。所以，你应该做的是，

在堆上分配对象并手动处理。

Hello,

The following doesn''t compile due to absence of the copy constructor in class FileStream:

FileInfo ^ fi = ...;
FileStream fs = fi->OpenRead();

The compiler is Beta 2. Is this supported? Planned to be supported?

Don''t answer just to answer. Look here: http://blogs.msdn.com/arich/ (DF

This pattern is for C++/CLI implemented classes only, the FCL are written in
C# and their classes can''t be "stack allocated". So, what you should do is,
allocate the object on the heap and manually dispose.
