请教：想把收到的最新的串口数据存到数组中，这个该怎么解决？这个是我做的，将NewData中的值赋给全局字符串str，发现会出问题，就是str = NewData.ToString();调试时发现 NewData中的数据并不是最新接到的数据，而是此时已经收到的全部数据，请问，我想收到最新收到的那些数据该怎么办？困扰好久了，多谢指教啊
public delegate void UpdateString(object NewData);
        public void UpdateRecevie(object NewData)
        {
            if (this.InvokeRequired)//等待异步
            {
                UpdateString _myInvoke = new UpdateString(UpdateRecevie);
                this.Invoke(_myInvoke, new object[] { NewData });
            }
            else
            {
                txtReceive.AppendText(NewData.ToString());
                txtReceive.SelectionStart = txtReceive.Text.Length - 1;
                txtReceive.ScrollToCaret();

               str = NewData.ToString();
               strCompare(str );
            }
        }
       private void strCompare(string str)
    {
        str0 = str;
        str1 = str0.Substring(0,5);
        str2 = str0.Substring(5,3);
        addtxt.Text = str1;
        temptxt.Text = str2;
    }

在你串口数据到达的那个处理方法中保存新的数据，然后就可以使用了

哦，我看看，前几天有考试，没上论坛，不知道有回复了，谢谢啦

我的串口事件是这样的
private void ComDevice_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            if (AllowReceive == true)
            {
                byte[] ReDatas = new byte[ComDevice.BytesToRead];//返回命令包
                ComDevice.Read(ReDatas, 0, ReDatas.Length);//读取数据
               
                StringBuilder sb = new StringBuilder();
                for (int i = 0; i < ReDatas.Length; i++)
                {
                    sb.AppendFormat("{0:x2}" + " ", ReDatas[i]);
                }
                UpdateRecevie(sb.ToString().ToUpper());

               
            }
            else
            {
                ComDevice.DiscardInBuffer();
            }
        }
要怎么把最新数据存到数组呢？

这个问题已经解决了，谢谢啊
