How can I ignore Excel cell value if text is struck through?

Question

I'm parsing an Excel spreadsheet using Microsoft's Excel Interop. I was instructed to ignore any values that have been "stricken through" (see image).

The code I'm using to get the value is simple:

string cellValue = Convert.ToString(cell.Value);

Maybe I could check each character in the cellValue to see if its ASCII code is beyond an acceptable range?

EDIT: With the help of the answer below, I was able to solve this by doing the following:

if (cellValue.Font.Strikethrough)
{
  continue;
}
  else
{
  // process value
}

You should retrieve the Cell Format. I don't have excel here but I think it should be something like:

myworksheet.Cells[row, col].Font.Strikethrough;

See this question: Reading text format from Excel using Microsoft.Office.Interop.Excel

If that doesn't work, look at answer of Danny, he tells you should check if a character is StrikeTrough.
