处置对象-AGAIN [英] Disposing of Objects -AGAIN
问题描述
我不认为我在前一个问题中明确说明了我的问题，所以让我再试一次
。我有以下内容：
作为位图的私人myobject
myobject = mybitmap（从屏幕的一部分创建）
我如何处理mybitmap对象的实例但保留myobject让我
可以再次使用它：
myobject = mysecondbitmap
如果我做了myobject.Dispose，我就不能再将变量myobject分配给另一个位图了。
另一个位图。如果我将myobject设置为空，mybitmap
和mysecondbitmap的瞬间仍然存在，必须等待GC处理
。

I don''t think I clearly stated my problem in my prior question so let me try
again. I have the following:
Private myobject as Bitmap
myobject = mybitmap (created from a part of the screen)
How do I dispose of the instance of mybitmap object yet retain myobject so I
can use it again like:
myobject = mysecondbitmap
If I do a myobject.Dispose, I can no longer assign the variable myobject to
another bitmap. If I set myobject to nothing, the instantance of mybitmap
and mysecondbitmap are still existing and have to wait for the GC to dispose
of them.

看看Bitmap.clone。

$ b $嗯......我不明白为什么你要处理这个实例如果你仍然需要它来支付它......

Mhm... I don''t understand why you want to dispose the instance if you still
need it...

我想处理我完成后创建的第一个位图使用它
并设置变量myObject来引用不同的位图，这样在下一次调用我的函数时，它将使用不同的位图。我不能将
变量作为参数传递，因为我正在使用MouseEvents。
" Dennis"写道：
I want to dispose of the first bitmap I created after I''ve finished using it
and set the variable myObject to reference a different bitmap so on the next
call to my functions, it will use the different bitmap. I can''t pass the
variable as a parameter because I am working with MouseEvents.

如果我做myobject.Dispose，我就不能将变量myobject更长时间分配给另一个位图。如果我将myobject设置为空，mybitmap
和mysecondbitmap的瞬间仍然存在，并且必须等待GC处理它们。
