调用 .Dispose() 后无法删除领域

Question

Loading in my data

Uri.TryCreate(realmPath, UriKind.Relative, out var outPathUri);
RealmConfigurationBase configuration = new FullSyncConfiguration(outPathUri, _currentUser, _realmFile)
{
    ObjectClasses = typesInSelectedRealm,
    SchemaVersion = 1
};

_realmInstance = Realm.GetInstance(configuration);

if(_realmInstance != null) _realmInstance.RealmChanged += LoadDataOnChange;

Trying to copy .realm file with same format from a USB Drive

if(_realmInstance != null) 
{
    _realmInstance.RealmChanged -= LoadDataOnChange; // figure it's good to clear all external references to Realm object
    _realmInstance.Dispose();
    GC.Collect();
    Thread.Sleep(1000); // both of these are me trying to just make darn sure that everything is cleaned up and has had enough time to do so
    Realm.DeleteRealm(_realmInstance.Config); // error
}

Error thrown: The process cannot access the file '...\\test.realm' because it is being used by another process.

I've already seen this thread , which is the closest I've found to my issue and a possible solution, although it was for IOS so I'm not sure how much is applicable to my situation.

It's likely that the Realm is still being used by the synchronization thread - eg if you added a whole lot of data to it and it hasn't been uploaded yet. What you can do is either wait for the upload to complete by calling:

await _realmInstance.GetSession().WaitForUploadAsync();
_realmInstance.Dispose();
// wait a second
// delete

or manually stopping the session (but that would it's possible that not all data has been uploaded):

_realmInstance.GetSession().Stop();
_realmInstance.Dispose();
