How to remove all hangfire recurring jobs on startup?

I am looking at using Hangfire as a job scheduler for recurring jobs. So configuring them is simple with AddOrUpdate, but then how do i delete it? I don't want to pollute my code with RecurringJob.RemoveIfExists() when that job has been deleted and then have to remember to delete it later.

Is there a way to get a list of all recurring jobs and delete them when the server starts and so my code will re add them in every time? If not, if there a better way?

e.g.

Application version 1: Added new Hangfire recurring job Do something 1

Application version 2: Added new Hangfire recurring jobs Do something 2 and Do Something 3

Application version 3: Removed Hangfire recurring job Do something 2

Problem: the job will still exist on the server with error "Could not load type..." and needs to be deleted.

according to hangfire docs

public static void RemoveIfExists(
    string recurringJobId
)

with this method, you can pass the job id which you want to delete.

RecurringJob.RemoveIfExists("exampleClassName.exampleFunctionName");

paul's answer was helpful but API api seems to have changed. Using Hangfire 1.6.20 I needed to get the recurring jobs from StorageConnectionExtensions

using (var connection = JobStorage.Current.GetConnection()) 
{
    foreach (var recurringJob in StorageConnectionExtensions.GetRecurringJobs(connection)) 
    {
        RecurringJob.RemoveIfExists(recurringJob.Id);
    }
}

A bit late on this one but hopefully it will help someone else. I got stuck in the same situation. In the end the answer on HangFire recurring task data helped me out.

I use the JobStorage to loop through all recurring jobs and remove each in turn as below:

using (var connection = JobStorage.Current.GetConnection())
{
    foreach (var recurringJob in connection.GetRecurringJobs())
    {
        RecurringJob.RemoveIfExists(recurringJob.Id);
    }
}

I am sure there is a nicer way out there but I couldn't find it
