Hello @phani sekhar ,
Thanks for the ask and using Microsoft Q&A platform .
I dont think there is any example in c# related to this . I think you can go and log an issues regarding the same here
https://github.com/microsoft/Analysis-Services.
In the mean time , you can ingest the records from blob to SQL and the refresh the model , its just an work around for the time being.
Please do let me know how it goes .
Thanks
Himanshu
