How to manually remove the RSACryptoServiceProvider utility?

Question

I read on MSDN ( see Important Note ) that RSACryptoServiceProvider should be removed. They give an example:

using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider()) 

Now I am trying to enable RSACryptoServiceProvider in MyClass using it in several methods. With this installation, I cannot use the using statement.

Instead, I try to call the .Dispose () method of the RSACryptoServiceProvider object at the appropriate time, but then I get a compilation error:

`System.Security.Cryptography.AsymmetricAlgorithm.Dispose (bool) 'is unavailable due to protection level

Perhaps RSACryptoServiceProvider is not used for more than one function call (using the using statement)?

How can I fix this, doesn't make the Dispose option an option?

Answer 1

The Clear method looks like it will call the dispose method:

This method is a simple call to the IDisposable.Dispose method. The Dispose call allows you to reallocate resources used by the AsymmetricAlgorithm class for other purposes. For more information about the utility, see Cleaning Unmanaged Resources.
