我有一个BsonValue abc并且正在寻找一种方法来检查它是否包含数组。结构如下：
"abc":[
"key1": "value1",
"key2": "value2",
.
.
"mno":{
"pqr":[
"valuefirst",
"valuesecond"
]
},
.
.
]
在C＃代码中，当我尝试检查数组pqr是否存在时
if(abc["mno"]["pqr"] != null)，我得到了KeyNotFoundException。如果abc或pqr存在mno或abc，则将filter编入索引是错误的。那么，如何检查存储为BsonValue的BsonDocument是否存在这些并克服异常？考虑使用 > git rev-parse --is-inside-work-tree # timeout=10
