[Cryptoc1]

Version

Describe the bug
When constructing a BsonValue from an array of strings, calling .ToString() throws a NullReferenceException.

Code to Reproduce

var tags = ["hello", "world"];

var value = new BsonValue(tags);

// THROWS!
value.ToString();

Expected behavior
.ToString() should return the string representation of the array.
