I call AddOrUpdate method from RecurringJob like that
public override string StartWork()
{
RecurringJob.AddOrUpdate<SomeScenario>(jobEntity.Name, x => x.Execute(jobEntity.Name), cron, TimeZoneInfo.Utc);
}
I need to rewrite this method, to reflection call. I found proper method overload
MethodInfo addOrUpdate = typeof(RecurringJob).GetMethods().Where(x => x.Name == "AddOrUpdate" && x.IsGenericMethod && x.IsGenericMethodDefinition).Select(m => new
{
Method = m,
Params = m.GetParameters(),
Args = m.GetGenericArguments()
})
.Where(x => x.Params.Length == 5
&& x.Params[0].ParameterType == typeof(string)
&& x.Params[2].ParameterType == typeof(string)
&& x.Params[3].ParameterType == typeof(TimeZoneInfo)
&& x.Params[4].ParameterType == typeof(string)
)
.Select(x => x.Method).FirstOrDefault();
I Hold proper type in db, so I will get it like that
Type type = Type.GetType(jobEntity.ScenarioType);
MethodInfo generic = addOrUpdate.MakeGenericMethod(type);
So, now I need to invoke this method with prooper parameters.
public static void AddOrUpdate<T>(string recurringJobId, Expression<Action<T>> methodCall, string cronExpression, TimeZoneInfo timeZone = null, string queue = "default")
Problem: I don't know how to generate Expression<Action<T>>
in this case, to invoke generic.Invoke(this, new object[] { jobEntity.Name, Expression<Action<T>>, cron, TimeZoneInfo.Utc, null });
Thank you a lot, for any help.
