C#多線程開發3：給線程傳遞數據的兩種方法

C#多線程開發3：給線程傳遞數據的兩種方法

定義需要傳遞給線程的數據。

class Student 
{
    public string Name { get; set; }
    public int Age { get; set; }
    public int Score { get; set; }
}
List studentList = new List() { 
            new Student(){Name="zhangsan",Age=20,Score=5},
            new Student(){Name="lisi",Age=18,Score=4},
            new Student(){Name="wangwu",Age=19,Score=5}
};

static void Main(string[] args)
{
     Thread t = new Thread(new ParameterizedThreadStart(MethodWithParameters));
     t.Start(studentList);
}
static void MethodWithParameters(object o) 
{
     List studentList = (List)o;
     foreach (Student s in studentList)
     {
          Console.WriteLine(s.Name + "," + s.Age + "," + s.Score);
     }
}

可以利用這個object類型的參數傳遞數據給線程。

方法2：將線程執行的方法與線程需要的數據封裝進同一個類

class ThreadModel
{
    private List studentList;
 
    public ThreadModel(List studentList)
    {
        this.studentList = studentList;
    }
 
     public void ThreadMethod()
     {
         foreach (Student s in studentList)
         {
             Console.WriteLine(s.Name + "," + s.Age + "," + s.Score);
          }
     }
}
static void Main(string[] args)
{
    ThreadModel threadModel = new ThreadModel(studentList);
    Thread t = new Thread(new ThreadStart(threadModel.ThreadMethod));
    t.Start(); 
}

在創建ThreadModel類對象時，通過構造函數傳入線程需要的數據。
