How to convert string into ObjectId

Question

I am getting data from MongoDB and binding to a WPF datagrid.

My code selects multiple rows, retrieves IDs and updates the selected records:

var server = MongoServer.Create(this.connectionString);
var db = server.GetDatabase(DATABASE);
var viewTrue = db.GetCollection(RISKALERT_TBL);
var count = viewTrue.Count();
foreach (RiskSettings row in grdRiskAlerts.SelectedItems)
{
    viewTrue.Update(Query.EQ("ID",row.ID), Update.Set("View", "False"));
    LoadandBindData();
}

But it does not update the record.

I thought maybe row.id is returning string and ID datatype is objectId.

This query is working for other datatype except the above case.

Answer 1

I came across the same issue when setting up a public property for the ObjectID.

My property converted the ObjectID to a string, and back to an ObjectID using the following code snippet.

The ObjectID wasn't coming up as an option so I had to use the complete namespace, to access the .Parse() like this MongoDB.Bson.ObjectId.Parse

    public string Id
    {
        get { return Convert.ToString(_id); }
        set { _id = MongoDB.Bson.ObjectId.Parse(value); }
    }

Hope this helps!
