C# BsonDocument - How to check if field is an array

Question

I receive a BsonDocument whose structure I do not know. I go through all properties, but I want to handle arrays differently. How do I find out if the field is an array?

foreach(var property in bsonDoc){
   if(/**check if its an array field**/){
     //do something
  }
}

Answer 1

The answer is pretty simple, I guess I was a little confused. Nevertheless, I will post a solution.

As Eldar already commented there is a bool property that says if a BsonValue is a BsonArray:

foreach(var property in bsonDoc){
   if(property.IsBsonArray){
     //do something
  }
}

Here also works the is operator: property is BsonArray

Which has the advantage that you can create a variable of the type at the same time, so I recommend this variant:

foreach(var property in bsonDoc){
   if(property is BsonArray arrayProperty){
     doSomething(arrayProperty);
  }
}
