which line in your code above gives this error?

if its this line
---- base.Dispose( disposing ); }

then you must have not derived your class from any user defined class.
thus default base class "object" .. which does not implement IDisposable()

Replace the line

C#

base.Dispose( disposing );

by

C#

IDisposable disposable = base as IDisposable;
if (disposable != null)
{
    disposable.Dispose(disposing);
}

In case that your base class does not implement IDisposable, the disposable object will be null - do not call Dispose here.
And the method in your class should be public or public virtual or public override, not only protected.

Solution 1

You are using protected in Dispose. Thus you need to ensure object inherits a Disposable object.
This is normally done by implementing an IDisposable interface.

Implementing IDisposable and the Dispose Pattern Properly[^] should help you.
