Convert the value to string with ToString method, then use Substring method to extract the part of string you need.

Hello,

I'm new to the forum and learning C#. So I'm probably going to take some blasting over the next few months for not having clean code. But I figured a good way to get good at C# is to practice. I thought maybe I could look and form post and try to solve them and that would not only help the poster but also myself.

Here is what I came up with for your question.

public static void Main(string[] args)
{
int i = 256893; //original int
string s = i.ToString(); //convert it to a string
s = s.Substring(0,3); //substring it out starting at 0 index and ending 3 chars in

Console.WriteLine(s);

}
