How to get "Size(column value) of Total Commit (Process View)" using Microsoft.Windows.EventTracing

Is there a way to get 'Size' column of "Total Commit-Process View" (Which is shown in WPA) using "Microsoft.Windows.EventTracing".

I am generated ETL file(using WPR), and in the "Size' column of the 'Total Commit(Process View), i get Size value in the WPA.

I would like to get the same result using "Microsoft.Windows.EventTracing" c# code.

Can someone through some pointers.

ThanksSanthi
