本文介绍了一个用于查询游戏角色信息的方法，通过输入玩家ID等参数，从服务器获取并展示角色的各项属性值。此外，还展示了如何利用反射遍历对象属性进行显示。

protected void RoleSearch(string strPlayerID, string strServerID, string strRoleName)
    {
        try
        {
            SrvRefs.OperationLog(string.Format("角色信息查询:[IP:{0}]", StringUtils.GetClientIP()));
            CPlayerInfo PlayerInfo;
            string strErrInfo;
            CCMGameInterface gi = new CCMGameInterface(ushort.Parse(strServerID), (ushort)1001);
            int iRetCode = gi.QueryPlayerInfo(ulong.Parse(strPlayerID), out PlayerInfo, out strErrInfo);
            if (iRetCode == 1)
            {
                lab_RoleName.Text = strRoleName;
                lab_Level.Text = PlayerInfo.Level.ToString();
                lab_Career.Text = PlayerInfo.Career.ToString();
                lab_HP.Text = PlayerInfo.HP.ToString();
                lab_MP.Text = PlayerInfo.MP.ToString();
                lab_Block.Text = PlayerInfo.Block.ToString();
                lab_Money.Text = PlayerInfo.Money.ToString();
                lab_PhyDef.Text = PlayerInfo.PhyDef.ToString();
                lab_PhyCritical.Text = PlayerInfo.PhyCritical.ToString();
                lab_PastLevel.Text = PlayerInfo.PastLevel.ToString();
                lab_ShiftTimes.Text = PlayerInfo.SoulShiftTimes.ToString();
                tab_PlayerInfo.Visible = true;

                DataTable dt = new DataTable();
                dt.Columns.Add("属性名称",typeof(string));
                dt.Columns.Add("属性值", typeof(string));
                DataRow dr = null;
                System.Reflection.PropertyInfo[] ps = PlayerInfo.GetType().GetProperties();
                foreach (System.Reflection.PropertyInfo pi in ps)
                {
                    dr = dt.NewRow();
                    string name = pi.Name;
                    string value = Convert.ToString(pi.GetValue(PlayerInfo, null));
                    dr["属性名称"] = name;
                    dr["属性值"] = value;
                    dt.Rows.Add(dr);
                }
                gv_Roles.DataSource = dt;
                gv_Roles.DataBind();
            }
            else
            {
                MsgBoxs.MsgBox(this, strErrInfo);
            }
        }
        catch (Exception ex)
        {
            LogManager.WriteTextLog("GM", "Role_RoleSearch", "btn_RoleSearch_Click", ex.Message);
        }
    }
