不能像方法一样使用不可调用的成员“” [英] Non-invocable member '' cannot be used like a method
问题描述
我正面临一个问题。
所以我会立即把代码;
public static List< ushort> blockedOpcodes = new List< ushort>();
public static bool isOpcodeAllowed(ushort opcode)
{
lock(locker)
{
if(blockedOpcodes.Contains(opcode))
{
Log1.LogMsg(Oops!有人试图发送一个阻塞的数据包:0x {+ opcode +:X});
return false;
}
return true;
}
}
public static void Load()
{
lock(locker)
{
StreamReader阅读器;
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);
}
}
}
}
这些都在一个叫做Program的类中。我想要做的是从blockedOpcodes收集数据'opcodes'。
if(Project_name.Program.blockedOpcodes(current.Opcode))
..
错误:
错误1不可调用的成员Project_name。 Program.blockedOpcodes'
不能像
方法那样使用。 C:\Users\skipper\Desktop\Project_name\without\src2 -
Copy\Project_name\Clients.cs 584 63 Project_name
任何帮助将不胜感激,谢谢!
PS:我是C#的初学者我已经开始了7天前。
if(Project_name.Program.blockedOpcodes [current.Opcode]!= 0)
而不是这样:
if .program.blockedOpcodes(current.Opcode))
因为
blockedOpcodes
是一个列表而不是一个方法。
编辑:你需要比较你的列表值和
0
(或任何您认为是无效值),因为您在列表中存储int值。
编辑:检查给定的OpCode是否在你的列表只需调用这个:
if(blockedOpcodes.Contains(current.Opcode)){/ * ... * /}
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); } } } }
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))
That's where the error shows up..
Error:
Error 1 Non-invocable member 'Project_name.Program.blockedOpcodes' cannot be used like a method. C:\Users\skipper\Desktop\Project_name\without\src2 - Copy\Project_name\Clients.cs 584 63 Project_name
Any help would be appreciated, thank you! PS: I'm a beginner in C# I have started like 7 days ago..
解决方案Obviously you need
if (Project_name.Program.blockedOpcodes[current.Opcode] != 0)
instead of this:
if (Project_name.Program.blockedOpcodes(current.Opcode))
Because
blockedOpcodes
is a list rather then a method.EDIT: 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.EDIT: To check if a given OpCode is within your list simply call this:
if (blockedOpcodes.Contains(current.Opcode)) { /* ... */ }
