Hi @Ala Qabaja,

For Getting last modified date in azure blob container use below code,

DateTime date =DateTime.Now;using(var filestream =File.OpenRead(@"D:\test.txt")){
               block.UploadFromStream(filestream);
               block.Metadata["lastmodifydate"]= date.ToString();
               block.SetMetadata();}
           block.FetchAttributes();string dateInfo= block.Metadata["lastmodifydate"];
