var a =(int)Convert.ToDouble("1.2");

Note if you're using comma as a number separator in your operating system, you have to use IFormatProvider:

var a =(int)Convert.ToDouble("1.2",CultureInfo.InvariantCulture.NumberFormat);

Another way to accomplish this task:

var a =int.Parse("1.2".Split('.')[0]);
