You can't compare a string to an integer in C# - they are not compatible. As far as the compiler is concerned, you might be trying to compare the word "Dolphins" with the number 42 - which is just silly.

There are ways to do what you want, but they will depend to a large extent on what kind of data you have to play with. For example, is the data you are retrieving from your database numeric in the first place? Have a look at the table definition, and find out. If it is a number, then don't convert it to a string, convert it to a number instead (which is pretty must a case of placing (int) or (double) in front of the get_data call and changing the type of "Basic" to an int or double as needed), and then use that.

If it is a string, then you need to Parse it to a number before you can use it, but if it is a number-in-a-string then why are you storing it as a string in the first place?
