Easy way to compare values of more than 3 variables?

Question

I want to check whether these variables have same values.

EXAMPLE:

int a = 5;
int b = 5;
int c = 5;
int d = 5;
int e = 5;
. . .
int k = 5;

if(a==b && b==c && c==d && d==e && .... && j==k)  
{
   //this is Complex way and not well understandable.
}

Any easy way to Compare all are same?
LIKE in below example

if(a==b==c==d==e.....j==k)
{
    //Understandable but not work 
}

Answer 1

how about something like this:

if (Array.TrueForAll<int>(new int[] {a, b, c, d, e, f, g, h, i, j, k },
        val => (a == val))) {
    // do something
}

Answer 2

With this many variables, would it make sense to move them into an array?

You could then test to see if they are all equal using Linq expressions like myarray.Distinct().Count() == 1; or perhaps myarray.All(r => r == 5);

Answer 3

You could create a var args method to do that:

bool intsEqual (params int[] ints) { 
   for (int i = 0; i < ints.Length - 1; i++) {
       if (ints[i] != ints[i+1]) {
          return False;
       }
   }
   return True;
}

Then just call it with all your ints as parameters:

if (intsEqual(a, b, c, d, e, f, g, h, i, j, k)) {
    doSomeStuff();
}
