为什么我不能创建一个使用带参数的方法的线程？ [英] Why can I not create a thread that uses a method with arguments?
问题描述
每当我尝试创建一个新的 Thread floodT = new Thread（新的ThreadStart（fn.Flood（fcmd））; 时，它总会给我一个错误告诉我预期的方法名称。
我完全迷失了，我一直在MSDN上阅读有关线程方法的旧存档教程。（线程教程（C＃） [ ^ ]）我想我一直在努力大概一个小时。我只是卡住了。
请大家帮忙，非常感谢！
提示：所有重要代码都在FloodCmd（）方法中启动。
我的代码：
public class 命令
{
public voi d 帮助（）
{

}
public class 网络
{
public void FloodCmd（ String 地址）
{
var fcmd = address.Remove（< span class =code-digit> 0 ， 6 ）; // 摆脱cmd中的FLOOD，留下地址。
尝试
{
Ping ping = new Ping（）;
// 关于线程的注意事项：由于某种原因，它们必须完全不同
// master-class。
NetTools fn = new NetTools（）;
线程floodT = 新线程（ new ThreadStart（fn.Flood（fcmd）））; // 这就是它为我提供语法错误的代码。帮助！
floodT.Start（）;
ping.Send（fcmd）;
}
catch （例外e）
{
System.Diagnostics.Debug.Write（ 洪水错误： + e.Message）;
Program.WriteError（e.Message）;
}
}
}
}
public 类 NetTools
{
公开 无效洪水（ 字符串地址）
{
while （ true ）
尝试
{
Ping ping = new Ping（）;
ping.Send（地址）;
}
catch （例外e）
{
Program.WriteError（e.Message）;
}
}
}
我尝试了什么：
我在互联网上看过教程，我记得这个社区有多好。而且我想把我的困难带给公众，让大家从中学到一点点。
首先，你的评论是错误的：没有线程要求在一个不同的班级。你只需要小心你所引用的内容。
这就是DoS攻击程序开始的样子。
不要去那里！
NetTools fn = new NetTools（）;
线程floodT = 新线程（ new ThreadStart（（）= > fn.Flood（fcmd）））;
floodT.Start（）;
是解决这个问题的一种方法。
另一个：
NetTools fn = new NetTools（）;
线程floodT = 新线程（ new ParameterizedThreadStart（fn.Flood））;
floodT.Start（fcmd）;
并添加
public void Flood（ object 地址）
{
Flood（地址 as string ）;
}
事实上，你的Flood方法都可以是静态的。
这改变了上面的内容以消除
NetTools fn = new NetTools（）;
line并更改
fn.Flood
to
NetTools.Flood
我认为你在寻找的是： ParameterizedThreadStart Delegate（System.Threading） [ ^ ]
这里有一个可以作为起点的工作示例。

Every time I attempt to create a new Thread floodT = new Thread(new ThreadStart(fn.Flood(fcmd));, it will always give me an error telling me "Method name expected."
I am completely lost, and I've been on MSDN reading an old archived tutorial about threading methods. (Threading Tutorial (C#)[^]) I think I've been working on this for probably an hour. I'm just stuck.
Please help, and thanks a lot in advance!
HINT: All the important code starts in the FloodCmd() method.
My code:
public class Command
{
public void Help()
{
... Some other really really long code goes here, but I saved you reading time. Oh, and since you're here, I'm a thirteen year old programmer, and message me on Skype: facebook:luke.wilson.1293575 Okay, now I need to get back to this, because I have mad ADD xc
}
public class Network
{
public void FloodCmd(String address)
{
var fcmd = address.Remove(0, 6); // Get rid of "FLOOD " in the cmd, leaving it with the address.
try
{
Ping ping = new Ping();
// NOTE ABOUT THREADS: for some reason they have to be in an entirely different
// master-class.
NetTools fn = new NetTools();
Thread floodT = new Thread(new ThreadStart(fn.Flood(fcmd))); // This right here is the code it's giving me syntax errors for. HELP!
floodT.Start();
ping.Send(fcmd);
}
catch (Exception e)
{
System.Diagnostics.Debug.Write("Error in flood: " + e.Message);
Program.WriteError(e.Message);
}
}
}
}
public class NetTools
{
public void Flood (String address)
{
while (true)
try
{
Ping ping = new Ping();
ping.Send(address);
}
catch (Exception e)
{
Program.WriteError(e.Message);
}
}
}
What I have tried:
I've looked all over the internet for tutorials, and I remembered how nice this community is. And I'd like to bring my difficulties to the public for everyone to learn a little bit from.
First, your comment is wrong: there's no requirement for threads to be in a different class. You just have to be careful about what you're referencing.
This has the appearance of the beginnings of a DoS attack program.
Don't go there!
NetTools fn = new NetTools(); Thread floodT = new Thread(new ThreadStart(() => fn.Flood(fcmd))); floodT.Start();
Is one way to solve this.
Another:
NetTools fn = new NetTools(); Thread floodT = new Thread(new ParameterizedThreadStart(fn.Flood)); floodT.Start(fcmd);
and add
public void Flood (object address) { Flood(address as string); }
In fact, your Flood method(s) can all be static.
This changes the above to eliminate the
NetTools fn = new NetTools();
line and change the
fn.Flood
to
NetTools.Flood
I think what you are looking for is this: ParameterizedThreadStart Delegate (System.Threading)[^]
There is a working example there that you can use as a starting point.
