[.NET Driver] "Disconnecting" an object from MongoDB

[Karsten Kaehler]

Hi folks,

I need some help!

If I try something like this

     var collection = _database.GetCollection<SomeObject>("Records");

     foreach (SomeObject s in collection.ToList())
     {
         anotherObject.SomeProperty = s.SomeProperty;
     }

where anotherObject is not mapped to a MongoDb Collection I get an access to the database everytime I try to read from anotherObject.SomeProperty, which gives me a huge performance hit.

How can I get rid of this behaviour?

Many thanks!

Hi Karsten,

Could you please answer the following:

• How do you observe the “access to the database” every time you read anotherObject.SomeProperty?
• How do you measure the performance hit ?
• What is the value type of SomeProperty ? i.e. is it another object ?
• Could you provide example mapping of the classes ?
• Which version of MongoDB C# driver are you using ?

Kind regards,

Wan.
