How to combine a Partial Class Object in C#?
public class Sample{
    public string name {get;set;}
    public int price {get;set}
}

Sample sampleA = new Sample();
 sampleA.name = "test";

  Sample sampleB = new Sample();
  sampleB.price = 100;

Sample sampleC = sampleA + sampleB;

sampleC.name = "test";
  sampleC.price = 100;

public static Sample operator +(Sample left, Sample right)
    {
        left.price = right.price;
        return left;
    }

public partial class File { public string Prop2 { get;set; } }

public partial class File { public int Prop1 { get;set; } }

public partial class File
{
     public string Prop2 { get;set; }
     public int Prop1 { get;set; }
}

Sample sampleA = new Sample();
sampleA.name = "test";
sampleA.price = 200;

Sample sampleB = new Sample();
sampleB.price = 100;

Sample sampleC = sampleA + sampleB; // what would be the value of price here: from sampleA or sampleB?

public static Sample operator +(Sample sampleA, Sample sampleB){
    return new Sample() { Name = sampleA.Name, Price = sampleB.Price };
}
