Delete excel rows based on multiple criteria in different columns

Question

I would like to know how I could incapsulate the following action in a if() statement, if possible.

I would like my program to check the excel file and see if I have an empty cell in COL A Cell 1 , COL B Cell 1, and COL C Cell 1 lets say, then it should delete that entire row.

My idea (that did not work) was to create ranges for each of these and make an if block out of it, but it didn't work as i would have wanted it to.

xl.Range colA = MySheet.Range["A:A"];      
xl.Range colB = MySheet.Range["B:B"];
xl.Range colC = MySheet.Range["C:C"];

if(colA.SpecialCells(xl.XlCellType.xlCellTypeBlanks) && colB.SpecialCells(xl.XlCellType.xlCellTypeBlanks) && colC.SpecialCells(xl.XlCellType.xlCellTypeBlanks))
            {
                MySheet.Range[MyRange].EntireRow.Delete();
            }

Any idea would be most appreciated seeing as i am stumped. I have also tried making the range into a string, and checking for NullOrEmpty cells, but it didn't work.
