LIST< T>将其分配给字符串 [英] LIST<T> assign it to string

问题描述

全部好，

列表<经销商> dealer = new List< Dealer>（）
 {
 new Dealer {Location = new Location（）{Lat = 1.1，Long = 1.2}，DealerCode =Dealer1，Address = new Address（）{ City =CITY1，State =STATE1}}，
 new Dealer {Location = new Location（）{Lat = 2.1，Long = 2.2}，DealerCode =Dealer2，Address = new Address（）{ City =CITY2，State =STATE2}}，
 new Dealer {Location = new Location（）{Lat = 3.1，Long = 3.2}，DealerCode =Dealer3，Address = new Address（）{ City =CITY3，State =STATE3}} 
}; 
 

我希望这个列表被分配到一个字符串中，我对此通用不太好。



你能帮帮我吗？

解决方案

最简单的方法是在Dealer类中创建一个返回字符串版本的方法 - 和显而易见的候选人是ToString：

  public   override   string  ToString（）
 {
  return   string  .Join（ ，Location.Lat.ToString（） ，Location.Long.ToString（），DealerCode，
 Address.City，Address.State）; 
} 

然后您就可以在列表中使用它：

 List< string> strings = dealers.Select（d = >  d.ToString（））。ToList（）; 

或者对于单个字符串：

  string  str =  string  .Join（< span class =code-string> ，dealer.Select（d = >  d.ToString（）+   \ n））; 

HI All,

List<Dealer> dealers = new List<Dealer>()
                               {
                                new Dealer{ Location =new Location() {Lat=1.1, Long=1.2 }, DealerCode="Dealer1", Address=new Address() { City="CITY1", State="STATE1" } },
                                new Dealer{ Location =new Location() {Lat=2.1, Long=2.2 }, DealerCode="Dealer2", Address=new Address() { City="CITY2", State="STATE2" } },
                                new Dealer{ Location =new Location() {Lat=3.1, Long=3.2 }, DealerCode="Dealer3", Address=new Address() { City="CITY3", State="STATE3" } }
                               };

I want this list to be assigned into a string, im not good in this generic.

Can you help me?

解决方案

The easiest way to do it is to create a method in your Dealer class that returns a string version - and the obvious candidate is ToString:

public override string ToString()
   {
   return string.Join("", Location.Lat.ToString(), Location.Long.ToString(), DealerCode, 
                          Address.City, Address.State);
   }

You can then use that in your List like this:

List<string> strings = dealers.Select(d => d.ToString()).ToList();

Or for a single string:

string str = string.Join("", dealers.Select(d => d.ToString() + "\n"));
