Why calling Dispose() on BinaryReader results in compile error?

Question

I have the following class which uses BinaryReader internally and implements IDisposable.

class DisposableClass : IDisposable
    {
        private BinaryReader r         


        

Answer 1

It won't work because the Dispose method on BinaryReader has been explicitly implemented.

Instead of being implicitly implemented, as in:

public void Dispose()
{
}

...it has been explicitly implemented, as in:

void IDisposable.Dispose()
{
}

...which means it can only be accessed via the IDisposable interface. Therefore, you have to cast the instance to IDisposable first.
