C#: Getting a cell's value with Excel.interop

Question

I want to get the value of a cell from an excel file with a software in C#; NOT THE TEXT, because the text depend of the size of the column, and I must not change it myself,

Answer 1

From this post on MSDN it looks like you would want something like:

var cellRangeValue = rng_ResolutionCell.get_Value(System.Type.Missing);

Answer 2

I have often found codes a little more complex than needed all over. Basically reading a cell is as simple as:

Xl.Range rng = sheet.Cells[row, column] as Xl.Range;
return rng.Value2;

Answer 3

Also:

newWS = (Microsoft.Office.Interop.Excel.Worksheet)newWB.Worksheets[2];
newWS.Select();
string ExcelCellContent = (string)newWS.Cells[2, 1].Value2;

Usage:

if((string)(ws_Varsheet.Cells[x, y].Value2 != "")
{
   // process
}
