不可调用成员 '' 不能像方法一样使用 [英] Non-invocable member '' cannot be used like a method

问题描述

我现在正面临一个问题.所以我马上把代码放上来；

I'm facing a problem right naw. So i'll put the code right away;

public static List<ushort> blockedOpcodes = new List<ushort>();

    public static bool isOpcodeAllowed(ushort opcode)
    {
        lock (locker)
        {
            if (blockedOpcodes.Contains(opcode))
            {
                Log1.LogMsg("Oops! Someone tried to send a blocked packet: 0x{" + opcode + ":X}");
                return false;
            }
            return true;
        }
    }


    public static void Load()
    {
        lock (locker)
        {
            StreamReader reader;
            using (reader = new StreamReader("filter.txt"))
            {
                string str = null;
                while ((str = reader.ReadLine()) != null)
                {
                    blockedOpcodes.Add(Convert.ToUInt16(str));
                }
            }
            Log1.LogMsg("Opcode filter loaded!");
            using (reader = new StreamReader("specialip.txt"))
            {
                string item = null;
                while ((item = reader.ReadLine()) != null)
                {
                    specialIPs.Add(item);
                }
            }
        }
    }

所以这些都在一个名为程序"的类中我想要做的是收集数据操作码"以阻止blockedOpcodes"

So those are in a class called 'Program' What I'm trying to do is collect data 'opcodes' to block from 'blockedOpcodes'

if (Project_name.Program.blockedOpcodes(current.Opcode))

这就是错误出现的地方..

That's where the error shows up..

错误:

错误 1 ​​不可调用成员Project_name.Program.blockedOpcodes"不能像方法.C:UsersskipperDesktopProject_namewithoutsrc2 -复制Project_nameClients.cs 584 63 Project_name

Error 1 Non-invocable member 'Project_name.Program.blockedOpcodes' cannot be used like a method. C:UsersskipperDesktopProject_namewithoutsrc2 - CopyProject_nameClients.cs 584 63 Project_name

如有任何帮助，将不胜感激，谢谢！PS:我是 C# 的初学者，我 7 天前就开始了..

Any help would be appreciated, thank you! PS: I'm a beginner in C# I have started like 7 days ago..

推荐答案

显然你需要

if (Project_name.Program.blockedOpcodes[current.Opcode] != 0)

而不是这个:

if (Project_name.Program.blockedOpcodes(current.Opcode))

因为 blockedOpcodes 是一个列表而不是一个方法.

Because blockedOpcodes is a list rather then a method.

您需要将列表值与 0(或任何您认为无效"的值)进行比较，因为您将整数值存储在列表中.

You need to compare your list-value against 0 (or whatever you consider to be an "invalid" value) because you store int-values within the list.

要检查给定的操作码是否在您的列表中，只需调用:

To check if a given OpCode is within your list simply call this:

if (blockedOpcodes.Contains(current.Opcode)) { /* ... */ }
