Cannot Call Implemented Functions of Interface (The Name Does Not Exist In the Current Context)

I have a public interface that has two methods:

public interface IClickStrategy : IStrategy
{
        void InsertSending(MailingResult sending, string connectionString, string tableName);
        void InsertClick(ClickResult click, MailingResult mailing, int campaignId, string              connectionString, string tableName);
}

And I have a class that implements this interface functions. So when I implement these functions, they are correctly in place but of course they are not public:

void IClickStrategy.InsertSending(MailingResult sending, string connectionString, string tableName){
...
}

I'm trying to call this function from my class and it gives me an error that actually makes sense:

"The name 'InsertSending' does not exist in the current context."

What I want to know is how to use these functions inside my class? What is the correct way of doing this? Thanks.

Some food for thought - click me for reference

"Explicit interface member implementations serve two primary purposes:

Because explicit interface member implementations are not accessible through class or struct instances, they allow interface implementations to be excluded from the public interface of a class or struct. This is particularly useful when a class or struct implements an internal interface that is of no interest to a consumer of that class or struct.

Explicit interface member implementations allow disambiguation of interface members with the same signature. Without explicit interface member implementations it would be impossible for a class or struct to have different implementations of interface members with the same signature and return type, as would it be impossible for a class or struct to have any implementation at all of interface members with the same signature but with different return types.

The problem is that you're using explicit interface implementation. You don't have to do that. You could just write:

public void InsertSending(...)
{
    ...
}

and call the method normally elsewhere. If you want to use explicit interface implementation though, you can only call the method via a reference of the interface type, not your class type. So you can use:

IClickStrategy strategy = this;
strategy.InsertSending(...);

Personally I try not to use explicit interface implementation unless I have a really good reason for doing so - it tends to make things more complicated in my experience, with this just being one example of that.

It must be

public void InsertSending(MailingResult sending, string connectionString, string tableName){
...
}

inside a class, that is decorated as implementing this interface.
