ArangoDB 创建边缘集合

Question

I tried create collection of edges in c# via ArangoDB-NET driver ( https://github.com/yojimbo87/ArangoDB-NET ) and this code not working.. My code:

 var response = dbClient.Collection.Type(ACollectionType.Edge).KeyGeneratorType(AKeyGeneratorType.Autoincrement).WaitForSync(true).Create(
                "EdgesCollection");

dbClient is ADatabase object. Collection is created but document type is not edge. How can I do?

I'm not familiar with that driver, and your question seems to be related to implementation, not DB functionality. However, my best guess would be to omit the KeyGeneratorType and WaitForSync options:

var cType = ACollectionType.Edge;
var cName = "EdgesCollection";
var response = dbClient.Collection.Type(cType).Create(cName);

If this fails to work, then you may need to review the docs , maybe add some other options like KeyIncrement . Generally, I would accept the defaults and only modify (or provide explicit parameters for) things that you NEED to change (ie "don't work").
