c# - Check if an array exists in a BsonValue type -


i have bsonvalue abc , looking way check if contains array or not. structure below:

"abc":[ "key1": "value1", "key2": "value2", . . "mno":{ "pqr":[ "valuefirst", "valuesecond" ] }, . . ]

in c# code when try check if array pqr exists if(abc["mno"]["pqr"] != null), keynotfoundexception. wrong on part index abc pqr or mno when doesn't exist. so, how can abc stored bsonvalue checked existence of these , overcome exception? thought of using filter. works bsondocument(please correct me if wrong). work around this?

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
