控制台中的C#错误

本文关键字:错误 控制台 | 更新日期: 2023-09-27 18:29:43

我有一个我玩的游戏的来源。一旦我登录游戏,控制台就会抛出一个错误。错误如下:

System.ArgumentOutOfRangeException: Count cannot be less than zero.
Parameter name: count
   at System.String.RemoveInternal(Int32 startIndex, Int32 count)
   at ConquerServer.Extra.ItemIDManipulation.ChangeDigit(Byte Place, Byte To) in C:'Documents and Settings'Administrator'Desktop'ConquerServer'ConquerServer'Extra.cs:line 134
   at ConquerServer.Extra.ItemIDManipulation.ToComposeID(Byte EqPos) in C:'Documents and Settings'Administrator'Desktop'ConquerServer'ConquerServer'Extra.cs:line 235
   at ConquerServer.Entities.Character.EqpStats(Byte Pos, Boolean Equip) in C:'Documents and Settings'Administrator'Desktop'ConquerServer'ConquerServer'Entities'Character.cs:line 1361
   at ConquerServer.Entities.Character.SendExtra() in C:'Documents and Settings'Administrator'Desktop'ConquerServer'ConquerServer'Entities'Character.cs:line 1637

以下是代码:

public void ChangeDigit(byte Place, byte To)
            {
                string Item = Convert.ToString(ID);
                string N = Item.Remove(Place - 1, Item.Length - Place + 1) + To.ToString();
                N += Item.Remove(0, Place);
                ID = uint.Parse(N);
            }

if (EqPos == 1 || EqPos == 3)
                {
                    ChangeDigit(4, 0);
                    ChangeDigit(6, 0);
                }
Extra.ItemIDManipulation e = new Extra.ItemIDManipulation(Equipment[Pos].ID);
                uint PID = e.ToComposeID(Pos);

if (Equipment[i].ID != 0)
                    {
                        MyClient.SendData(Packets.AddItem(Equipment[i], i));
                        EqpStats(i, true);
                    }



我们将不胜感激!

控制台中的C#错误

请尝试使用此方法。

   public void ChangeDigit(byte Place, byte To) 
   { 
       string Item = Convert.ToString(ID, CultureInfo.InvariantCulture);
       if(Place > Item.Length || Place < 1)
           throw new ArgumentOutOfRangeException("Place");
       Item = Item.Remove(Place-1) + To.ToString() + Item.Substring(Place)
       ID = uint.Parse(Item, CultureInfo.InvariantCulture);
   } 

如果抛出异常,则表示ID错误/为空。

检查项目长度-位置+1是否大于0

您收到此错误是因为当您进行以下调用时:

ChangeDigit(4, 0);

ID的值长度不能少于3个字符。

例如,假设ID = "AB",当您在对ChangeDigit(4, 0)的调用中调用Item.Remove(Place - 1, Item.Length - Place + 1)时,它本质上是这样做的:

int startIndex = 4 - 1 // 3
int count = 2 - 4 + 1 // -1
"AB".Remove(startIndex, count)

正如您在这里看到的,count参数是-1,这将导致获得Count cannot be less than zero的异常。

您需要在调试器中启动程序,并查看抛出异常时的ID值。也许ID是一个空字符串,或者由于代码中其他地方的错误而不是您所期望的ID?
