Question

Like Math Max but takes 3 or params of int   thanks

You could use Enumerable Max   new      1  2  3   Max

If  for whatever reason  e g  Space Engineers API   System array has no definition for Max nor do you have access to Enumerable  a solution for Max of n values is  public int Max int   values        if values Length  lt  1            return 0            if values Length  lt  2            return values 0             if values Length  lt  3           return Math Max values 0   values 1               int runningMax   values 0       for int i 1  i lt values Length - 1  i             runningMax   Math Max runningMax  values i              return runningMax

This function takes an array of integers   I completely understand  Jon Skeet s complaint about sending arrays    It s probably a bit overkill       public static int GetMax int   array     must be a array of ints               int current greatest value   array 0      initializes it          for  int i   1  i  lt   array Length  i                             compare current number against next number              if  i 1  lt   array Length-1     prevent  index outside bounds of array  error below with array i 1                                   array i 1  exists                 if  array i   lt  array i 1     array i   lt   current greatest value                                           current val is less than next  and less than the current greatest val  so go to next iteration                     continue                                  else                                  array i 1  doesn t exist  we are at the last element                 if  array i   gt  current greatest value                                           current iteration val is greater than current greatest value                     current greatest value   array i                                     break     next for loop i index will be invalid                               if it gets here  current val is greater than next  so for now assign that value to greatest value             current greatest value   array i                      return current greatest value          Then call the function    int highest val   GetMax  new     1 6 2 72727275 2323        highest val   72727275

Let s assume that You have a List lt int gt  intList   new List lt int gt  1 2 3  if You want to get a max value You could do   int maxValue   intList Max

Well  you can just call it twice   int max3   Math Max x  Math Max y  z      If you find yourself doing this a lot  you could always write your own helper method    I would be happy enough seeing this in my code base once  but not regularly    Note that this is likely to be more efficient than Andrew s LINQ-based answer - but obviously the more elements you have the more appealing the LINQ approach is    EDIT  A  best of both worlds  approach might be to have a custom set of methods either way   public static class MoreMath          This method only exists for consistency  so you can  always  call        MoreMath Max instead of alternating between MoreMath Max and Math Max        depending on your argument count      public static int Max int x  int y                return Math Max x  y              public static int Max int x  int y  int z                   Or inline it as x  lt  y    y  lt  z   z   y     x  lt  z   z   x              Time it before micro-optimizing though          return Math Max x  Math Max y  z               public static int Max int w  int x  int y  int z                return Math Max w  Math Max x  Math Max y  z                public static int Max params int   values                return Enumerable Max values             That way you can write MoreMath Max 1  2  3  or MoreMath Max 1  2  3  4  without the overhead of array creation  but still write MoreMath Max 1  2  3  4  5  6  for nice readable and consistent code when you don t mind the overhead   I personally find that more readable than the explicit array creation of the LINQ approach

As generic  public static T Min lt T gt  params T   values        return values Min       public static T Max lt T gt  params T   values        return values Max

off topic but here is the formula for middle value   just in case someone is looking for it  Math Min Math Min Math Max x y   Math Max y z    Math Max x z

You could try this code    private float GetBrightestColor float r  float g  float b         if  r  gt  g  amp  amp  r  gt  b            return r        else if  g  gt  r  amp  amp  g  gt  b             return g        else if  b  gt  r  amp  amp  b  gt  g             return b

Linq has a Max function   If you have an IEnumerable lt int gt  you can call this directly  but if you require these in separate parameters you could create a function like this   using System Linq        static int Max params int   numbers        return numbers Max        Then you could call it like this  max 1  6  2   it allows for an arbitrary number of parameters

[c#] In c# is there a method to find the max of 3 numbers?
