語法

'Declaration

    Get

'Usage
Dim value As ThreadPoolScheduler

value = Scheduler.ThreadPool

public static ThreadPoolScheduler ThreadPool { get; }

屬性值

類型： System.Reactive.Concurrency.ThreadPoolScheduler
執行緒集區排程器。

備註

ThreadPool 排程器會排程在 .NET 執行緒集區上執行的動作。 此排程器適合用於短期執行的作業。

範例

此程式碼範例會使用 Generate 運算子來產生整數序列，其正方形小於 1000。 與產生運算子相關聯的處理會排程為使用 ThreadPool 排程器在 .NET 執行緒集區上執行。

using System;
using System.Reactive.Linq;
using System.Reactive.Concurrency;

namespace Example
{
  class Program
  {
    static void Main()
    {
      //*********************************************************************************************//
      //*** Generate a sequence of integers which are the perfect squares that are less than 100  ***//
      //*********************************************************************************************//

      var obs = Observable.Generate(1,                      // Initial state value
                                    x => x * x < 1000,      // The termination condition. Terminate generation when false (the integer squared is not less than 1000)
                                    x => ++x,               // Iteration step function updates the state and returns the new state. In this case state is incremented by 1 
                                    x => x * x,             // Selector function determines the next resulting value in the sequence. The state of type in is squared.
                                    Scheduler.ThreadPool);  // The ThreadPool scheduler runs the generation on a thread pool thread instead of the main thread.

      using (IDisposable handle = obs.Subscribe(x => Console.WriteLine(x)))
      {
        Console.WriteLine("Press ENTER to exit...\n");
        Console.ReadLine();
      }
    }
  }
}
