static void Main()
{
int i, j, temp,mid;
int[] arr = new int [10] {10,20,30,40,50,60,70,80,90,100};

Console.WriteLine("Array before swapping is : ");
foreach (int a in arr)
{
Console.WriteLine(a + "\t");
}

mid = (arr.Length)/2;
for (i = 0, j = mid; i < arr.Length - 1, j < arr.Length; i++,j++)
{
temp = arr[i];
arr[i] = arr[mid + 1];
arr[mid + 1] = temp;
}

Console.WriteLine("Array before swapping is : ");
foreach (int a in arr)

You can not add more than one condition in the For Loop..
You need to specify inner loop for that, with the different logic...

sorry but i saw over internet and books that we can add 2 conditions in a loop at a time... i am just doubtfull about the syntax is correct or not

you can use more conditions with logical operator like:
&& (and) , || (or)..
not like (,)comma separator, which you used in "initializer" and "iterator"(increments or Decrements) part

I made this for you:-

C#

using System;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            int i, j, temp, mid;
            int[] arr = new int[10] { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };

            Console.WriteLine("Array before swapping is : ");
            foreach (int a in arr)
            {
                Console.WriteLine(a + "\t");
            }

            mid = (arr.Length) / 2;
            //for (i = 0, j = mid; i < mid ; i++, j++)
            //{
            //    temp = arr[i];
            //    arr[i] = arr[mid];
            //    arr[mid] = temp;
            //}
            j = mid;
            for (i = 0; i < mid; i++)
            {
                temp = arr[i];
                arr[i] = arr[j];
                arr[j++] = temp;
            }
            Console.WriteLine("Array After swapping is : ");
            foreach (int a in arr)
            {
                Console.WriteLine(a + "\t");
            }
           
            Console.ReadKey();
        }
    }
}
