我想处置的IDisposable的对象（的FileStream ^ FS）的托管C ++（.NET 2.0），并正在错误

I'm trying to Dispose of an IDisposable object(FileStream^ fs) in managed C++ (.Net 2.0) and am getting the error

'Dispose' : is not a member of 'System::IO::FileStream'

它说，我应该调用析构函数来代替。在调用

It says that I should invoke the destructor instead. Will calling

fs->~FileStream();

调用FileStream对象的Dispose方法？为什么我不能调用Dispose？

call the dispose method on the FileStream object? Why can't I call Dispose?

推荐答案

正确的模式是直接删除的对象：

The correct pattern is to just delete the object:

delete fs;

这将被转换成一个调用Dispose（）

This will be translated into a call to Dispose()

请参阅此帖子一些的引擎盖下是怎么回事细节。这个成语的好处是，它可以让你写的：

See this post for some of the details of what is going on under the hood. The advantage of this idiom is that it allows you to write:

{
  FileStream fs(...)
  ...
}

和调用了Dispose方法正确......相当于用块在C＃。文件流对象仍然分配在托管堆中。

And have the Dispose method called correctly ... equivalent to a using block in C#. The file stream object is still allocated on the managed heap.
