带参数的多线程的方式
#region 执行带一个参数的多线程
Thread mythread = new Thread(new ParameterizedThreadStart(Calculate));
mythread.IsBackground = true;
mythread.Start(500);
#endregion
private void Calculate(object Max) //带一个参数的委托函数
{
int max = (int)Max;
Stopwatch stopwatch = Stopwatch.StartNew();
for (int i = 0; i < max; i++)
{
Thread.Sleep(5);
}
stopwatch.Stop();
long lSearchTime = stopwatch.ElapsedMilliseconds;
MessageBox.Show(lSearchTime.ToString() + "毫秒");
}
方式一: 定义一个类,将要传的参数设置为类的属性,然后将参数值赋值给类的属性,将类作为一个参数进行传达,以下代码通过两个参数示例,多个参数一样,代码如下
class MyClass
{
public int Max { get; set; }
public int Min { get; set; }
}
#region 第一种方式:执行带多个参数的多线程
MyClass model = new MyClass();
model.Max = 500;
model.Min = 0;
Thread mythread1 = new Thread(new ParameterizedThreadStart(CalculateTwo));
mythread1.IsBackground = true;
mythread1.Start(model);
#endregion
private void CalculateTwo(object Myclass) //带多个参数的委托函数
{
MyClass model = (MyClass)Myclass;
Stopwatch stopwatch = Stopwatch.StartNew();
for (int i = model.Min; i < model.Max; i++)
{
Thread.Sleep(5);
}
stopwatch.Stop();
long lSearchTime = stopwatch.ElapsedMilliseconds;
MessageBox.Show(lSearchTime.ToString() + "毫秒");
}
方式二:lambda表达式的方式,简单方便,代码如下:
#region 第二种方式:执行带多个参数的多线程
Thread mythread2 = new Thread(() => CalculateThree(500, 0));
mythread2.IsBackground = true;
//設置為後臺線程,程式關閉后進程也關閉,如果不設置true,則程式關閉,此線程還在內存,不會關閉
mythread2.Start();
#endregion
private void CalculateThree(int Max,int Min) //带多个参数的委托函数
{
Stopwatch stopwatch = Stopwatch.StartNew();
for (int i = Min; i < Max; i++)
{
Thread.Sleep(5);
}
stopwatch.Stop();
long lSearchTime = stopwatch.ElapsedMilliseconds;
MessageBox.Show(lSearchTime.ToString() + "毫秒");
}
