❔ Pass variable type as class parameter

Hey, so basically I have a class

class Number
{
  public string Type;
  public string Value;

  public Number(string type, string value)
  {
    Type = type;
    Value = value;
  }
}

class Number
{
  public string Type;
  public string Value;

  public Number(string type, string value)
  {
    Type = type;
    Value = value;
  }
}

What I want to do is if I do this for example

var num = new Number("long", "10000");

var num = new Number("long", "10000");

Number.Type shouldnt be string but rather a

long

long

;
and Number.Value should contain the value
