//2.获得程序自身版本号

using System.Reflection;

Assembly.GetExecutingAssembly().GetName().Version.ToString();

//3.线程与界面窗体同步通讯

方法一用Invoke:

        delegate void SetLogCallBack(string msg);

        private void SetLog(string msg)
        {
            try
            {
                if (Textlog.InvokeRequired)
                {
                    SetLogCallBack aSetLog = new SetLogCallBack(SetLog);
                    this.Invoke(aSetLog, new object[] { msg});
                }
                else
                {
                    Textlog.AppendText(msg + "/r/n");
                    Textlog.SelectionStart = Textlog.Text.Length;
                    Textlog.ScrollToCaret();
                }
            }
            catch
            {
            }
        }

方法二event+BeginInvoke:

public delegate void TransactNotifyEventHandler(object sender, TransNotifyEventArgs e);

public class TransManager
{

        Thread t;

        #region Event
        public event TransactNotifyEventHandler TransNotify;

        protected virtual void OnTransNotify(TransNotifyEventArgs e)
        {
            if (TransNotify != null)
            {
                TransNotify(this, e);
            }
        }
        #endregion

        public bool Start()
        {
            t = new Thread(new ThreadStart(this.TransThreadPorc));
            t.Start();
            return true;
        }

        private void TransThreadPorc()
        {

                OnTransNotify(new TransNotifyEventArgs("hello world"));

        }

}

 

 

///窗口界面部分

        TransManager transMgr = new TransManager();
        private void FrmMain_Load(object sender, EventArgs e)
        {
          transMgr.TransNotify += new TransactNotifyEventHandler(TransactNotify);
            try
            {
                transMgr.Start();
            }
            catch
            {
            }
        }
        public void TransactNotify(object sender, TransNotifyEventArgs e)
        {
            if (this.InvokeRequired)
            {
                object[] param = new object[2] { sender, e };
                this.BeginInvoke(new TransactNotifyEventHandler(OnTransactNotify), param);
            }
            else
            {
                OnTransactNotify(sender, e);
            }
        }
        private void OnTransactNotify(object sender, TransNotifyEventArgs e)
        {

                    Textlog.AppendText(e.msg + "/r/n");
                    Textlog.SelectionStart = Textlog.Text.Length;
                    Textlog.ScrollToCaret();
        }

//4. string与byte[]转换

System.Text.Encoding.Default.GetString()

System.Text.Encoding.Default.GetBytes()

//int byte 转换

int i;

byte[] b=BitConverter.GetBytes( 0xba5eba11);

i= BitConverter.ToInt32(b, 0);
