小弟我需要定义一个checked变量，但checked是C#关键字，有没有办法解决

我需要定义一个checked变量，但checked是C#关键字，有没有办法解决
public class TreeNode
  {
  public string text;
  public string id;
  public string href;
  public bool leaf;
  public List<TreeNode> children;
  public bool checked; //出错
  }

我需要得到一个json
/// <summary>
  /// 创建父菜单下拉列表
  /// </summary>
  /// <param name = "ParentID"></param>
  public ActionResult ComboTree()
  {
  IList<MenuPermission> modelList = Bll.GetAll();
  List<TreeNode> TreeNode = new List<TreeNode>();
  TreeNode = GetTree(null, modelList,false);
  return this.Json(TreeNode, JsonRequestBehavior.AllowGet);
  }

  private static List<TreeNode> GetTree(string PID, IList<MenuPermission> modelList, bool type)
  {
  List<TreeNode> treeNode = new List<TreeNode>();

  foreach (MenuPermission model in modelList)
  {
  if (PID == model.ParentID)
  {
  TreeNode treeModel = new TreeNode();
  treeModel.id = model.ID.ToString();
  treeModel.text = model.Name;
  if (type)
  {
  treeModel.href = model.URL;
  }
  treeModel.children = GetTree(model.ID.ToString(), modelList, type);
  if (treeModel.children.Count == 0)
  treeModel.leaf = true;
  else
  treeModel.leaf = false;
  treeModel.checked = false;
  treeNode.Add(treeModel);
  }
  }
  return treeNode;
  }

页面上需要这个checked不知道应该怎么解决？

[解决办法]
你为这个蛋疼只说明你不好好看书不认真看文档...

方法有三...

1.大写...Checked...

2.加@...@checked...

但是...这两个其实跟你的问题没关系...

3.指定序列化成员名称...
[DataMember(Name = "checked")]
public bool IsChecked;
