SharePoint Batch Update Auto Increment Field Value

Question

Hello All,

I am making use of SharePoint List Batch Updating methodology in order to update the items in bulk. I build the query dynamically for each and every item using StringBuilder and process the data ultimately using 'ProcessBatchData' Method.

Now, I have a requirement where I have to increment a particular field value in the query while iterating through each item for building the query. How can I auto-increment a field value for each item in the batch query?
