Take latest value from complex collection
i'm getting data from MongoDb in sorted order with key[not unique] as AB ,so i have to club the response and take the top unique values based on key using Linq[c#]
Response :
[{
"AB": "XY",
"BC": "TRAVEL",
"CD": "75",
"EF": "21"
},
{
"AB": "TY",
"BC": "STOP",
"CD": "344",
"EF": "55"
},
{
"AB": "XY",
"BC": "STOP",
"CD": "45",
"EF": "44"
},
{
"AB": "ZZ",
"BC": "STOP",
"CD": "89",
"EF": "33"
},
{
"AB": "TY",
"BC": "STOP",
"CD": "67",
"EF": "88"
},
{
"AB": "ZZ",
"BC": "TRAVEL",
"CD": "14",
"EF": "55"
}
]
Response is in sorted format i.e first response is latest
The result that i want to produce is :
[{
"AB": "XY",
"BC": "TRAVEL",
"CD": "75",
"EF": "21"
},
{
"AB": "ZZ",
"BC": "STOP",
"CD": "89",
"EF": "33"
},
{
"AB": "TY",
"BC": "STOP",
"CD": "344",
"EF": "55"
}]
as the AB key can contain different values

Well, you could utilize LINQ GroupBy method:
var filteredResponse = response.GroupBy(o => o.AB).Select(g => g.First()).ToList();
