我們的目標是從串口發送數據到文本框，以及在數據網格視圖。我們應該怎麼做？任何意見或建議將不勝感激。順便說一句，我們使用的是C＃的Visual Studio 2012

 string RxString; 

     public Form1() 
     { 
      InitializeComponent(); 
     } 

     private void buttonStart_Click(object sender, EventArgs e) 
     { 
      serialPort1.PortName = "COM71"; 
      serialPort1.BaudRate = 9600; 

      serialPort1.Open(); 
      if (serialPort1.IsOpen) 
      { 
       buttonStart.Enabled = false; 
       buttonStop.Enabled = true; 
       dataGridView1.Rows.Add(10); 
      } 
     } 

     private void buttonStop_Click(object sender, EventArgs e) 
     { 
      if (serialPort1.IsOpen) 
      { 
       serialPort1.Close(); 
       buttonStart.Enabled = true; 
       buttonStop.Enabled = false; 

      } 

     } 

     private void Form1_FormClosing(object sender, FormClosingEventArgs e) 
     { 
      if (serialPort1.IsOpen) serialPort1.Close(); 
     } 

     private void textBox1_KeyPress(object sender, KeyPressEventArgs e) 
     { 

      if (!serialPort1.IsOpen) return; 

      char[] buff = new char[1]; 

      buff[0] = e.KeyChar; 


      serialPort1.Write(buff, 0, 1); 


     } 



     private void DisplayText(object sender, EventArgs e) 
     { 
      textBox1.AppendText(RxString); 


     } 

     private void serialPort1_DataReceived 
     (object sender, System.IO.Ports.SerialDataReceivedEventArgs e) 
     { 
      RxString = serialPort1.ReadExisting(); 
      this.Invoke(new EventHandler(DisplayText)); 
      dataGridView1.Rows[0].Cells[0].Value = textBox1.Lines[0]; 

     } 




    } 

}

我不知道如何將數據從文本在DataGridView轉移到每一行。請幫助：'（

香港專業教育學院使用這這些代碼，但仍然沒有工作，它說的是方法必須返回類型

private DataTable myTable = new DataTable(); 



    public Form2() 

    { 

     InitializeComponent(); 

     // initialise 

     this.initialiseTable(this.myTable); 
     // set source 

     this.dataGridView1.DataSource = this.myTable; 

    } 

    /// <summary> 

    /// Initialise a table 

    /// </summary> 

    /// <param name="table">The table to initialise</param> 

    private void initialiseTable(DataTable table) 

    { 

     // add all columns 

     table.Columns.Add(new DataColumn("Column1")); 

     table.Columns.Add(new DataColumn("Column2")); 

     table.Columns.Add(new DataColumn("Column3")); 

    } 

    private void button1_Click(object sender, EventArgs e) 

    { 

     // create a row 
     DataRow rd = this.myTable.NewRow(); 
     // set values 

     rd[0] = textBox1.Text; 

     rd[1] = textBox2.Text; 

     rd[2] = textBox3.Text; 
     // add row to table 
     this.myTable.Rows.Add(rd); 
    } 


    } 
} 

我只是有什麼上面顯示的圖片文件

假設你的DataGridView是綁定與3列。

假設你在txtBox1文本由分離 ''

所以

string[] txt = textBox1.Text.Split(','); 
dataGridView1.Rows.Add(txt[0], txt[1], txt[2]); 

希望這確實有助於

private void DisplayText(object sender, EventArgs e) 
    { 
     textBox1.AppendText(RxString); 
     DataGridView1.Rows.Add(RxString); //consider 1 row has only 1 column 
    }
