为什么您认为这是一种不好的做法？这可能是一个非常好的（或最佳）实践，因为对象将在 using 块之后立即被处理。
Why do you think it's a bad practice? It can be a very good (or best) practice since the object will be disposed immediately after the using block.
不——这根本不是不好的做法——在许多情况下，这是非常好的做法。
使用“using”方法，您可以编写代码，知道
IDisposable类型一旦超出范围就会自动释放，这意味着您无需手动调用Dispose()在代码的每个出口点。话虽如此，您当然可能会想出一些
Dispose()的糟糕用法，但它本质上并不是坏事，而且通常是好的。No - it isn't bad practice at all - in many cases it is extremely good practice.
Using the "using" approach, you can write code knowing that
IDisposabletypes are automatically disposed of as soon as they go out of scope, meaning you don't need to manually callDispose()at every exit point to your code.Having said that, you can certainly come up with some bad usages of
Dispose(), but it is not intrinsically bad, and more often than not is good.
