Try this -

double a; int b;

a = Convert.ToDouble(Console.ReadLine()); // Value in double

b = Convert.ToInt32(Console.ReadLine()); // Value in Int

Try using 

Console.ReadLine();

ex:

Console.Writeline("1. Do Something");
string input = Console.ReadLine();

Use Console.ReadLine to read input as string and then convert them to your required type, using int.Parse or int.TryParse, or double.Parse, or double.TryParse like:

string input = Console.ReadLine();

int temp;

if (int.TryParse(input, out temp))
{
    //valid int input
}
else
{
    //invalid int input

}
Console.WriteLine(temp); //input number

Its better if you use TryParse family of methods for parsing, since they will not raise an exception in case of failed parsing.

Use Console.ReadLine() that lets you to put an input and you can assign it to the input you wish, if int then parse it.

You need to read a line of textual input using Console.ReadLine(), then parse it as a number using int.Parse() or double.TryParse() or other variants.
