/// <summary>
/// 查询命令
/// </summary>
private DelegateCommand<string> _queryCommand;
public DelegateCommand<string> QueryCommand
{
    get
    {
        if (_queryCommand == null)
        {
            _queryCommand = new DelegateCommand<string>(QueryCommandExecuted);
        }
        return _queryCommand;
    }
}
private void QueryCommandExecuted(string sn)
{
            
}
