Converting object of a class to of another one

Question

I have two classes which have are nearly equal except the data types stored in them. One class contains all double values while other contains all float values.

Answer 1

You could add an implicit type conversion operator:

public class DoubleClass
{
    public double X;
    public double Y;
    public double Z;

    public static implicit operator FloatClass(DoubleClass d)
    {
        return new FloatClass { X = (float)d.X, Y = (float)d.Y, Z = (float)d.Z };
    }
}

Now this works:

DoubleClass doubleObject = new DoubleClass();
FloatClass convertedObject = doubleObject;

Answer 2

You can use Conversion Operators to achieve this.

Fr example:

struct FloatClass
{
    public FloatClass(DoubleClass dClass) {
        //conversion...
    }
    ... 
    public static explicit operator FloatClass(DoubleClass dClass) 
    {
        FloatClassd = new FloatClass(dClass);  // explicit conversion

        return d;
    }
}


var convertedObject = (FloatClass)doubleObject;

Answer 3

Sounds like you could use generics here:

 public class GenericClass<T>
 {
    T X { get; set; }
    T Y { get; set; }
    T Z { get; set; }
 }

 GenericClass<float> floatClass = new GenericClass<float>();
 GenericClass<double> doubleClass = new GenericClass<double>();

Answer 4

Use a conversion operator:

public static explicit operator FloatClass (DoubleClass c) {
   FloatCass fc = new FloatClass();
   fc.X = (float) c.X;
   fc.Y = (float) c.Y;
   fc.Z = (float) c.Z;
   return fc;
}

And then just use it:

var convertedObject = (FloatClass) doubleObject;

Edit

I changed the operator to explicit instead of implicit since I was using a FloatClass cast in the example. I prefer to use explicit over implicit so it forces me to confirm what type the object will be converted to (to me it means less distraction errors + readability).

However, you can use implicit conversion and then you would just need to do:

var convertedObject = doubleObject;

Answer 5

Best way is Serialize object and again desalinize it

Answer 6

The simplest way to do this is by using serializer. Use Newtonsoft JSON serializer which works best.

using Newtonsoft.Json;

  private void Convert()
    {
        DoubleClass doubleClass = new DoubleClass {X = 123.123, Y = 321.321, Z = 111.111};
        var serializedoubleClass = JsonConvert.SerializeObject(doubleClass);
        var floatClass = JsonConvert.DeserializeObject(serializedoubleClass, typeof(FloatClass));
    }
