SQL>值太大

Question

我想用SQL做一個插件，我得到一些錯誤，我不知道如何處理它們。 SQL數據庫管理器+從主類添加播放器。

private void Events_OnPlayerConnected(UnturnedPlayer player) 
     { 
      FriendsGroupID_t id; 
      id.m_FriendsGroupID = (short)player.SteamGroupID.m_SteamID; 
      Database.addPlayer(player.CharacterName, player.SteamName, SteamFriends.GetFriendsGroupName(id), player.CSteamID.m_SteamID.ToString()); 
     } 

其他代碼：

using System; 
using I18N.West; 
using MySql.Data.MySqlClient; 
using Rocket.Core.Logging; 
using Steamworks; 

namespace SQLPlayer 
{ 

    internal class DatabaseController 
    { 

     private MySqlConnection createConnection() 
     { 
      MySqlConnection Connection = null; 
      try 
      { 
       if (SQLPlayer.Instance.Configuration.Instance.DatabasePort == 0) 
       { 
        SQLPlayer.Instance.Configuration.Instance.DatabasePort = 3306; 
       } 
       Connection = new MySqlConnection(string.Format("SERVER={0};DATABASE={1};UID={2};PASSWORD={3};PORT={4};", new object[] 
       { 
        SQLPlayer.Instance.Configuration.Instance.DatabaseAddress, 
        SQLPlayer.Instance.Configuration.Instance.DatabaseName, 
        SQLPlayer.Instance.Configuration.Instance.DatabaseUsername, 
        SQLPlayer.Instance.Configuration.Instance.DatabasePassword,

      } 
      catch (Exception) { } 
      return Connection; 
     }

        mySqlCommand.ExecuteNonQuery(); 
       } 
       mySqlConnection.Close(); 
      } 
      catch (Exception ex) 
      { 
       Logger.LogException(ex); 
      } 
     }

       mySqlCommand.ExecuteNonQuery(); 
       mySqlConnection.Close(); 
      } 
      catch (Exception) { } 
     } 


     public void DeletePlayers() 
     { 
      try

       MySqlConnection mySqlConnection = createConnection(); 
       MySqlCommand mySqlCommand = mySqlConnection.CreateCommand();

       mySqlCommand.CommandText = commandText;

       mySqlConnection.Close(); 
      } 
      catch (Exception) { } 
     } 
    } 
} 

這是當我打電話的機能的研究addPlayer我收到錯誤：

Answer 1

您的問題是這一行：

id.m_FriendsGroupID = (short)player.SteamGroupID.m_SteamID; 

The m_SteamID值可能是int，並且太大而不適合short類型的變量。這裏最好的解決方案是確保id.m_FriendsGroupID也是int類型，並將演員移除到short。
