一：使用ParameterizedThreadStart委托
如果使用了ParameterizedThreadStart委托，线程的入口必须有一个object类型方式一：使用ParameterizedThreadStart委托:
using System;
using System.Threading;
namespace ThreadWithParameters
{
class Program
{
static void Main(string[] args)
{
string hello = "hello world";
//这里也可简写成Thread thread = new Thread(ThreadMainWithParameters);
//但是为了让大家知道这里用的是ParameterizedThreadStart委托，就没有简写了
Thread thread = new Thread(new ParameterizedThreadStart(ThreadMainWithParameters));
thread.Start(hello);
Console.Read();
}
static void ThreadMainWithParameters(object obj)
{
string str = obj as string;
if(!string.IsNullOrEmpty(str))
Console.WriteLine("Running in a thread,received: {0}", str);
}
}
}
这里稍微有点麻烦的就是ThreadMainWithParameters方法里的参数必须是object类型的，我们需要进行类型转换。
二：利用lambda表达式
using System.Threading;
namespace ThreadWithParameters
{
class Program
{
static void Main(string[] args)
{
string hello = "hello world";
//如果写成Thread thread = new Thread(ThreadMainWithParameters(hello));这种形式，编译时就会报错
Thread thread = new Thread(() => ThreadMainWithParameters(hello));
thread.Start();
Console.Read();
}
static void ThreadMainWithParameters(string str)
{
Console.WriteLine("Running in a thread,received: {0}", str);
}
}
}
