If an exception occurs inside a "using" block, is the Dispose method called?

.net, c#, dispose, exception, using

Solution

Yes it will get called.

`using` translates into `try-finally` block, so even in case of recoverable exception `Dispose` gets called.

See: using statement C#

The using statement ensures that Dispose is called even if an exception occurs while you are calling methods on the object. You can achieve the same result by putting the object inside a try block and then calling Dispose in a finally block; in fact, this is how the using statement is translated by the compiler.

Consider `SqlConnection` which implements `IDisposable` interface, so the following:

using (SqlConnection conn = new SqlConnection("connectionstring"))
{
    //some work
}

Would get translated into

{
    SqlConnection conn = new SqlConnection("connectionstring");
    try
    {
        //somework
    }
    finally
    {
        if (conn != null)
            ((IDisposable)conn).Dispose(); //conn.Dispose();
    }
}

Problem

In C#, if an exception occurs inside a "using" block, does the Dispose method get called?
