Fill range. Value2 in Excel to interact with string

I am importing some values ​​from Excel sheets in a C # application. One column is mostly text, but can contain any values. I used the following:

Range range = ... // getting this from Excel, works fine
string myString = (string)range.Value2;

      

        
        
        
      

    

When a cell contains text, it works. But when it contains 123 for example, the debugger shows 123.0 for the range. Value2 and the conversion to string fails.

I wonder how to write the most general transform for all types of cells. At least string and integer can be floating point content.
