Determine if an int is within range

Question

Can I somehow make this a bit cleaner using Math.[Something], without making a method for it?

int MaxSpeed = 50;

if (Speed.X > MaxSpeed)
    Speed.X = MaxSpeed;

if (Speed.X < MaxSpeed * -1)
    Speed.X = MaxSpeed * -1;

if (Speed.Y > MaxSpeed)
    Speed.Y = MaxSpeed;

if (Speed.Y < MaxSpeed * -1)
    Speed.Y = MaxSpeed * -1;

Answer 1

There's a method in XNA called MathHelper.Clamp that does what you need. I understand if you don't want to import XNA libraries for this one function, though. You can do this with extension methods. Here's an implementation that uses generics (so you can apply it to various types) so you can use it for ints, longs, anything that implements IComparable

static class Extensions
{
    public static T Clamp<T> (this T self, T min, T max) where T: IComparable
    {
        if (self.CompareTo( min) <0)
            return min;
        return self.CompareTo(max) > 0 ? max : self;
    }
}

I'm afraid there is no such built-in method. There is a similar question here where an extension method is proposed to force the number to be in range (copy-pasting it with cosmetic changes here):

public static class InputExtensions
{
    public static int LimitToRange(this int value, int inclusiveMinimum, int inclusiveMaximum)
    {
        if (value < inclusiveMinimum) 
            return inclusiveMinimum;
        if (value > inclusiveMaximum)
            return inclusiveMaximum;
        return value;
    }
}
