1 for 01 => maximum - inclusive, minimum - exclusive. More generic version for other ranges (notice that second argument is count, not end): There is temptation to write if solution without && like 1 <= x <= 100 - that look really elegant, but in C# leads to a syntax error "Operator '<=' cannot be applied to operands of type 'bool' and 'int'".

If 'max' and 'min' are independent variables, the extra subtraction for (max-min) will waste time, but if that expression can be precomputed at compile time, or if it can be computed once at run-time to test many numbers against the same range, the above expression may be computed efficiently even in the case where the value is within range (if a large fraction of values will be below the valid range, it may be faster to use if ((value >= min) && (value <= max)) because it will exit early if value is less than min). Here, we are going to use a VBA code to check the values of the Order List column in the range of the Product List column. If the number is not in range like 11,0,1,23 etc., we will print one message that it is not valid and the program will ask again to enter a valid number.

Why does range(start, end) not include end? The only other comment I'd make is that if you're checking inputs with the intention to throw an exception, you should consider using code contracts: This is more elegant than if() throw new Exception(), and you could even get compile-time warnings if someone tries to call your method without ensuring that the number is in bounds first.
