C#  是如何运行的，我是刚介入C#的，是像MFC一样，通过消息机制来运行的吗？
比如看懂以下语句，需要具备哪些知识，下面语句是如何运行的？请回答
   private void Start_Click(object sender, EventArgs e)
        {
            if (this._settings.rbRunTypeOnce)
            {
                this._taskRepeatInterval = 0;
                this._taskRepeatCnt = 0;
            }
            else {
                this._taskRepeatInterval = (int)(this._settings.numInterval * 1000 * 60);
                this._taskRepeatCnt = (int)(this._settings.numRepeatCount);
            }

            bwFetch.RunWorkerAsync();

可能我没有表达清楚，我主要是问下面语句，是如何运行的，看懂它，需要看哪些知识，请推荐一本这方面的好书   
if (this._settings.rbRunTypeOnce)
            {
             this._taskRepeatInterval = 0;
                this._taskRepeatCnt = 0;
            }
            else {
                this._taskRepeatInterval = (int)(this._settings.numInterval * 1000 * 60);
                this._taskRepeatCnt = (int)(this._settings.numRepeatCount);
            }

            bwFetch.RunWorkerAsync();

谢谢版主对语句的解释！说到了程序的意思！

程序中有下面语句：
1、  
private Settings _settings = Settings.Default;
3、
 internal sealed partial class Settings {
        
        public Settings() {
            // // 若要为保存和更改设置添加事件处理程序，请取消注释下列行:
            //
            // this.SettingChanging += this.SettingChangingEventHandler;
            //
            // this.SettingsSaving += this.SettingsSavingEventHandler;
            //
        }


3、初始化：
 this.bwFetch = new ();

  // bwFetch
            //
            this.bwFetch.WorkerReportsProgress = true;
            this.bwFetch.WorkerSupportsCancellation = true;
            this.bwFetch.DoWork += new (this.bwFetch_DoWork);
            this.bwFetch.RunWorkerCompleted += new (this.bwFetch_RunWorkerCompleted);
            //
程序执行到  “bwFetch.RunWorkerAsync();开始在后台执行操作”，请问在后台哪里执行啊？怎么才能找到它？


      

程序执行到  “bwFetch.RunWorkerAsync();后，会转到哪里去执行呢？知道的请告诉一下

谢谢版主指教
