I'm not too familiar with excel interop, however it appears there is no Delete function for a columns collection. I wonder if the single column object can be deleted so get your collection of columns using xlWorksheetNew.Columns["P:Q"] and maybe do a for each column in that columns collection? Worth a try if the above code you supplied is not working.

One thing is to re-check the type of xlWorksheetNew is it correctly defined.

Another thing is that if you want to cast the columns before Delete is called, you need to apply parenthesis. In other words

C#

((Excel.Range)xlWorksheetNew.Columns["P:Q"]).Delete();
