What is the equivalent of the C# “using” block in IronPython?

问题

What's the equivalent of this in IronPython? Is it just a try-finally block?

using (var something = new ClassThatImplementsIDisposable())
{
  // stuff happens here
}

回答1:

IronPython supports using IDisposable with with statement, so you can write something like this:

with ClassThatImplementsIDisposable() as something:
    pass

回答2:

IronPython (as of the 2.6 release candidates) supports the with statement, which wraps an IDisposable object in a manner similar to using.

回答3:

With statement. For example:

with open("/temp/abc") as f:
    lines = f.readlines()

回答4:

There is the with statement: http://www.ironpythoninaction.com/magic-methods.html#context-managers-and-the-with-statement

with open(filename) as handle:
    data = handle.read()
    ...

回答5:

the using block is in fact the following under the hood:

try {
  (do something unmanaged here)
}
finally {
  unmanagedObject.Dispose();
}

Hope this helps you understand the logic behind the using statement.
