The function should return a string representation of a double type number in the IEEE754 format

public class GetIEEE754FormatAdapter : ITransformer<double, string>
    {     
        public string Transform(double obj)
        {
            return Encoding.UTF8.GetString(BitConverter.GetBytes(obj));
        }
    }

For example if obj is 122.625, the result should be a string 0100000001011110101010000000000000000000000000000000000000000000

My implementation is returning wrong result

This does the trick:

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(BinaryString(122.625));
        // 00000001011110101010000000000000000000000000000000000000000000
    }

    static string BinaryString(double value)
    {
        long bits = BitConverter.DoubleToInt64Bits(value);
        return Convert.ToString(bits, 2).Substring(1);
    }
}
