Returns a null value if the specified field does not exist.

Example

Bson value = Bson.emptyObject;
value["a"] = 1;
value["b"] = true;
value["c"] = "foo";
assert(value["a"] == Bson(1));
assert(value["b"] == Bson(true));
assert(value["c"] == Bson("foo"));

Returns a null value if the index is out of bounds.

Example

Bson[] entries;
entries ~= Bson(1);
entries ~= Bson(true);

Bson value = Bson(entries);
assert(value[0] == Bson(1));
assert(value[1] == Bson(true));
assert(value[2] == Bson("foo"));
