using keyword
suggest changeWhen an object implements the IDisposable
interface, it can be created within the using
syntax:
using (var foo = new Foo())
{
// do foo stuff
} // when it reaches here foo.Dispose() will get called
public class Foo : IDisposable
{
public void Dispose()
{
Console.WriteLine("dispose called");
}
}
using
is syntatic sugar for a try/finally
block; the above usage would roughly translate into:
{
var foo = new Foo();
try
{
// do foo stuff
}
finally
{
if (foo != null)
((IDisposable)foo).Dispose();
}
}
Found a mistake? Have a question or improvement idea?
Let me know.
