            Players.Items.Add();//Players为combobox      
                 //需要将所有的info.Nmae加到Players里面

            }

------解决方案--------------------
C# code

_playerlist =Program.CfgMgr.PlayersConfig.PlayerInfos.Select(a=>a.Nmae.Tostring()).ToArray();

------解决方案--------------------
foreach (PlayerInfo info in Program.CfgMgr.PlayersConfig.PlayerInfos)
           {       
                info.Nmae.Tostring();    
   //这里，你遍历以后没有添加，怎么会有呢，  
 Players.Items.Add(infro.name.toString());
//加到里面来，你去 打下断点看下就能明白，不然你还是不理解,F10再F11一步步的看，记得看他的值，相信你能明白
           }
          // Players.Items.Add();//Players为combobox     


------解决方案--------------------
private string[] _playerlist = new string[Program.CfgMgr.PlayersConfig.PlayerInfos.Count];//数组
  public Main()
       {
           InitializeComponent();
           for(int i=0;i<_playerlist.Length;i++)
           {
               _playerlist[i]=Program.CfgMgr.PlayersConfig.PlayerInfos[i].Nmae.Tostring();
           }
           Players.DataSource=_playerlist;
        }
我想你定义_playerlist这个数组是有原因的吧，我猜想了一下，你想要的是不是这个效果，希望对你有所帮助…
