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,

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

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