怎样给线程传递参数，new Thread(new ThreadStart(ThreadHandle))好像不行哇。

shuker(秋风儿，学习.net) ，好办法，通过传递参数能不能实现？

好像不可以的，ThreadStart她要求的是一个没有参数的接口
我都是这么来做的

System.Threading.Thread thScan= new Thread(new ThreadStart(ScanTarget));
thScan.Start();//Thread.Start 方法:啟動線程

我的问题是这样，
我要做一个网段扫描，
最大同时启动255个线程，
每个线程询问一个ip。我想过了，如果把它做成类，
当然可以解决存储它负责的ip的问题，
但这样使问题的复杂度突然上升。首先是在某一些线程解析ip的过程中我终止了程序，
线程管理是一个问题。
每一个线程搜索完毕后还要和主form通讯，把扫描结果交给主form。
这样又要在每一个对象内保持一个到主form的托管。
最后还要把已完成任务的Scaner对象销毁。这些都是使用类方法造成的复杂问题。求解法

你本来想怎么做，现在一样可以这么做的阿
本来是255个线程对象
现在是255个包装了线程对象的新类阿
没什么区别，而且新的类你可以添加上 start , stop等接口的

要我回答的话，我的答案将完全与 shuker(秋风儿，学习.net) 的相同。Wrox P2P 有一本《VB.NET 线程参考手册》书上对这种问题讲得很好，只能代码所用的语言不同，其原理是一样的，可以去好好看一下，有符合 shuker(秋风儿，学习.net) 所说的好例子。可能最近有了《C# 线程参考手册》了，留意一下。

要想简单，把每个Thread负责的ip地址赋给该Thread的name属性。在Thread运行的函数里通过：Thread.currentThread.name获得该ip地址。如果参数不止一个或者不能简单的赋给name，又不想向大家说的那样，建个HashTable好了，key是Thread，vaule是含有赋给该Thread参数的Class或者Status。

除非是使用线程连接池，但使用线程数又不能控制它的优先级和abort直接用Thread 必须用类传参，参见：http://expert.csdn.net/Expert/TopicView1.asp?id=1345305我以前曾写过一个端口扫描器，代码如下：里面有二个我的公用类：
ArLi.CommonPrj.getResPrj 是一个资源文件操作器，在我的http://expert.csdn.net/Expert/TopicView1.asp?id=1705200 里有
另一个ArLi.CommonPrj.MsgBox.Warning 就是一个MessageBox 你自己改成MessageBox.Show 就行了

255 并不算多，在现在的CPU周期上完全能处理。

把线程方法放到一个类中：Thread t=new Thread(net ThreadStart(new IPScaner(ipaddr,..其他想传递的~~).DoJob));
t.Start();
