将记录添加到列表

Question

这是我的公开课：

public class CharactersOnline
{
    public int connectionId;
    public int characterId;
    public string characterName;
}

这是我的代码：

public List<CharactersOnline> charactersOnline = new List<CharactersOnline>();
chraractersOnline[chraractersOnline.Count + 1].connectionId = 1;
chraractersOnline[chraractersOnline.Count + 1].characterId = 2;
chraractersOnline[chraractersOnline.Count + 1].characterName = "Test"; 

我的错误在哪里？为什么我无法将这些记录添加到列表中？

Answer 1

你可以这样做（未经测试）：

public List<CharactersOnline> charactersOnline = new List<CharactersOnline>();

var characterOnline = new CharactersOnline{connectionId = 1, characterId = 2, characterName = "test"}; //creates a new instance of your object

charactersOnline.Add(characterOnline); //adds the single new instance of your object to the list
