将数据存储到与类列表

问题描述

我有以下类：

public class EmailData
{
    public string FirstName{ set; get; }
    public string LastName { set; get; }
    public string Location{ set; get; }
}

然后我做了以下内容，但不能正常工作：

I then did the following but was not working properly:

List<EmailData> lstemail = new List<EmailData>(); 
lstemail.Add("JOhn","Smith","Los Angeles");

我得到一个消息，说不准过载方法需要3个参数。

I get a message that says no overload for method takes 3 arguments.

推荐答案

如果您希望实例，并添加在同一行，你必须做这样的事情：

If you want to instantiate and add in the same line, you'd have to do something like this:

lstemail.Add(new EmailData { FirstName = "JOhn", LastName = "Smith", Location = "Los Angeles" });

或以前只是实例化对象，并直接将其添加：

or just instantiate the object prior, and add it directly in:

EmailData data = new EmailData();
data.FirstName = "JOhn";
data.LastName = "Smith";
data.Location = "Los Angeles"

lstemail.Add(data);
