我要评论本文实例讲述了c#使用 parallel 类进行多线程编程的方法。分享给大家供大家参考。具体如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
using system.threading;
using system.threading.tasks;
using system.diagnostics;
using system.runtime.interopservices;
namespace threads
{
class program
{
[dllimport("kernel32.dll", charset = charset.auto, setlasterror = true)]
public static extern int getcurrentprocessornumber();
private static int criticalsection = 0;
private static object lockobject = new object();
static void main(string[] args)
{
console.writeline("==================sequential calls==============");
console.writeline();
target();
target();
target();
target();
target();
target();
target();
target();
console.writeline();
console.writeline("==================parallel calls==============");
console.writeline();
action action = new action(target);
parallel.invoke(new action[] { action, action, action, action, action, action, action, action });
console.readkey();
}
private static void target()
{
thread.sleep(2000);
lock (lockobject)
{
criticalsection++;
console.writeline(string.format("thread id: {0} and processor id: " +
"{1} critical variable value: {2}",
thread.currentthread.managedthreadid,
getcurrentprocessornumber(), criticalsection));
}
}
}
}
希望本文所述对大家的c#程序设计有所帮助。
