Do I need to call Close() on a ManualResetEvent?

Question

I\'ve been reading up on .NET Threading and was working on some code that uses a ManualResetEvent. I have found lots of code samples on the internet. However, when reading

Answer 1

In general, if an object implements IDisposable it is doing so for a reason and you should call Dispose (or Close, as the case may be). In the example you site, the ManualResetEvent is wrapped inside a using statement, which will "automatically" handle calling Dispose. In this case, Close is synonymous with Dispose (which is true in most IDisposable implementations that provide a Close method).

The code from the example:

using (var mre = new ManualResetEvent(false))
{
   ...
}

expands to

var mre = new ManualResetEvent(false);
try
{
   ...
}
finally
{
   ((IDispoable)mre).Dispose();
}
