收集被修改;

问题描述

限时删除！！

嘿伙计们，我收到的是一个收藏品被修改过;枚举操作可能无法执行。错误。 Everyting工作正常并且保存我只是得到了错误仍然是错误的。

  public   static   void  addItem（SocketUser用户，SocketGuild公会，Item项目， int 金额）
 {
 checkUser（用户，公会）; 
  if （getItemList（guild）.ContainsKey（item.Id））{
 List< localItem> inventory = getPlayerInventory（user，guild）; 
 List< string> playerList = getInventoryList（guild）; 
  if （inventoryContains（item，inventory））{
 localItem local =  new  localItem（）; 
 local = getLocalItem（inventory，item）; 
 inventory.Remove（getLocalItem（inventory，item））; 
 local.amount + =金额; 
 inventory.Add（local）; 
} 
  else  
 {
 localItem local =  new  localItem（）; 
 local.item = item; 
 local.amount + =金额; 
 inventory.Add（local）; 
} 
  foreach （ string  line  in  playerList）
 {
  if （line.Contains（user.Id.ToString（）））
 {
  string  newline = embedInventoryString（user.Id.ToString（），inventory）; 
 playerList.Remove（line）; 
 playerList.Add（换行符）; 
 File.WriteAllLines（  server data \\inventoryData + guild.Id。 ToString（）+   .json，playerList）; 
 Console.WriteLine（  done 2）; 
} 
} 
} 
} 
 

我尝试了什么：



我试过移动File.WriteAllLines，因为我认为它只是在错误的时间被修改，我没看到代码有什么问题？

解决方案

Hey guys, I'm getting a Collection was modified; enumeration operation may not execute. error. Everyting is working fine and saving i just get spat that error still.

public static void addItem(SocketUser user, SocketGuild guild, Item item, int amount)
{
    checkUser(user, guild);
    if (getItemList(guild).ContainsKey(item.Id)) {
        List<localItem> inventory = getPlayerInventory(user, guild);
        List<string> playerList = getInventoryList(guild);
        if (inventoryContains(item, inventory)) {
            localItem local = new localItem();
            local = getLocalItem(inventory, item);
            inventory.Remove(getLocalItem(inventory, item));
            local.amount += amount;
            inventory.Add(local);
        }
        else
        {
            localItem local = new localItem();
            local.item = item;
            local.amount += amount;
            inventory.Add(local);
        }
        foreach (string line in playerList)
        {
            if (line.Contains(user.Id.ToString()))
            {
                string newline = embedInventoryString(user.Id.ToString(), inventory);
                playerList.Remove(line);
                playerList.Add(newline);
                File.WriteAllLines("server data\\inventoryData" + guild.Id.ToString() + ".json", playerList);
                Console.WriteLine("done 2");
            }
        }
    }
}

What I have tried:

I've tried moving the File.WriteAllLines around because i was thinking it was just being modified at the wrong time, i don't see anything wrong with the code?
