我已經做了一個簡單的項目,從串口(arduino)讀取,我收到的數據,我可以把這些數據放入文本框,richtex,但我不能把它們放在數據網格中,實際上我需要把這些數據放在MSSQL表中,但也顯示在數據網格中。這裏是我試過的代碼:C#從串口讀取arduino
void _spManager_NewSerialDataRecieved(object sender, SerialDataEventArgs e)
{
if (this.InvokeRequired)
{
// Using this.Invoke causes deadlock when closing serial port, and BeginInvoke is good practice anyway.
this.BeginInvoke(new EventHandler<SerialDataEventArgs>(_spManager_NewSerialDataRecieved), new object[] { sender, e });
return;
}
int maxTextLength = 1000; // maximum text length in text box
if (tbData.TextLength > maxTextLength)
tbData.Text = tbData.Text.Remove(0, tbData.TextLength - maxTextLength);
// This application is connected to a GPS sending ASCCI characters, so data is converted to text
string str = Encoding.ASCII.GetString(e.Data);
tbData.AppendText(str);
tbData.ScrollToCaret();
richD.AppendText(str);
richD.ScrollToCaret();
dataGridView1.DataSource = str;
}
你能幫我填充datagridbiew嗎?
這是我得到的e.Data:
public class SerialDataEventArgs : EventArgs
{
public SerialDataEventArgs(byte[] dataInByteArray)
{
Data = dataInByteArray;
}
/// <summary>
/// Byte array containing data from serial port
/// </summary>
public byte[] Data;
}
