C# String greater than or equal code string

c#, string, string-comparison

Solution

A string is not a number, so you're comparing lexicographically(from left to right). `String.CompareTo` is used for ordering, but note that `"10"` is "lower" than `"2"` since the char `1` is already lower than the char `2`.

I assume what you want want is to convert it to an `int`:

int i1 = int.Parse(string1);
if (i1 < 10)
{
    Console.WriteLine("less than 10");
}
else if (i1 >= 10)
{
    Console.WriteLine("10 or more");
}

Note that you should use `int.TryParse` if `string1` could have an invalid format. On that way you prevent an exception at `int.Parse`, e.g.:

int i1;
if(!int.TryParse(string1, out i1))
{
    Console.WriteLine("Please provide a valid integer!");
}
else
{
    // code like above, i1 is the parsed int-value now
}

However, if you instead want to check if a string is longer or shorter than 10 characters, you have to use it's `Length` property:

if (string1.Length < 10)
{
    Console.WriteLine("less than 10");
}
else if (string1.Length >= 10)
{
    Console.WriteLine("10 or more");
}

Problem

I'm trying to get my code working my comparing if a string is bigger or less than 10, but it doesn't work correctly. It writes 10 or more even if the value is less than 10. ``` int result = string1.CompareTo("10"); if (result < 0) { Console.WriteLine("less than 10"); } else if (result >= 0) { Console.WriteLine("10 or more"); } ```
