如何使用内联分配在C＃对象中分配部分值

Question

I'm having a Collection of a Model

public class MobileModelInfo
{
    public string Name { get; set; }
    public string Catagory { get; set; }
    public string Year { get; set; }
}

Public Class MainClass
{
    public MainClass()
    {
        MobileModelInfo mobObject = new MobileModelInfo();
        mobObject.Name = "Apple iPhone 6";
        SetMobileDetails(mobObject);
    }

    private void SetMobileDetails(MobileModelInfo mobObject)
    {
        mobObject.Catagory = "Ultra Smart Phone";
        mobObject.Year = "2015";
    }
}

In the SetMobileDetails() Method set the partial values to the Object of MobileModelInfo. Here I need to assign the Values via Inline. How Can I achieve this

For Example: new MobileModelInfo() { Catagory = "Ultra Smart Phone", Year = "2015" }

Kindly assist me...

Note: One of the Property is set in Constructor and the remaining Properties is going to set in SetMobileDetails() Method.

Answer 1

You can use named parameter but you need to pass the value for properties of object

private void SetMobileDetails(string catagory="", string year="")
{
    //...
}

You probably need to have a constructor that all three property values

public MainClass(string name, string catagory="", string year="")
{
    mobObject.Name = name;
    SetMobileDetails(catagory: "Ultra Smart Phone", year : "2015");
}

Use below code to solve your problem thank you.

void SetMobileDetails(String Catagory String Year )
{

    new MobileModelInfo() { Catagory = "Ultra Smart Phone", Year = "2015" }

}

Also Make overload of this for when property are change like below

 void SetMobileDetails(String Catagory)
    {

        new MobileModelInfo() { Catagory = "Ultra Smart Phone"}

    }

This is all you need:

public class MobileModelInfo
{
  public string Name { get; private set; }
  public string Catagory { get; set; }
  public string Year { get; set; }

  public MobileModelInfo(string name)
  {
    Name = name;
  }
}

Usage:

var iphone = new MobileModelInfo("Apple iPhone") {Catagory = "Mobile", Year = "2016"};
