How to create indexes in MongoDB via .NET

Question

I\'ve programmatically created a new document collection using the MongoDB C# driver.

At this point I want to create and build indexes programmatically. How can I do

Answer 1

you should use CreateIndex as EnsureIndex is marked obsolete for future compatibility with the next versions of MongoDB:

var client = new MongoClient("mongodb://localhost");
var db = client.GetServer().GetDatabase("db");
var collection = db.GetCollection("Hamsters");

collection.CreateIndex(IndexKeys.Ascending(_ => _.Name));
