You don't actually need the inner for loop. All that is happening is that a 0 or a 1 is being prepended to the previous string. So you can do this.

C#

StringBuilder sb= new StringBuilder();
           int count = 5;

           for (int t = 1; t <= count; t++)
           {
               sb.Insert(0, t & 1);
               Console.WriteLine(sb);
           }

C#

static void Main(string[] args)
        {
           
            for (int i = 0; i <= 5; i++)
            {
                for (int j = 0; j <= i; j++)
                {
                    if (j % 2 == 0 && i % 2 == 0)
                    {
                        Console.Write("1");
                    }
                    else if (j % 2 != 0 && i % 2 != 0)
                    {
                        Console.Write("1");
                    }
                    else
                    {
                        Console.Write("0");
                    }
                }
                Console.Write("\n");
            }
            Console.Read();
        }

Alison beat me to it! just a small improvement to her solution - you don't need the if condition:

for (int j = i; j > 0; j--)
    {
    Console.Write("{0} ", j & 1);
    }
Console.WriteLine();

Since you code works nicely except that the 1's and 0's come out backwards, howabout starting the inner loop with j = i and reduce it by 1 each time, stopping at 1?
ie

for (j = i; j >= 1 ; j--)
{
      if (j % 2 == 0)
      {
            Console.Write("0 ");
      }
      else
      {
            Console.Write("1 ");
      }
}

I haven't tried it, just an idea for you. :)
