我做了一个简单的项目,从串口(arduino)读取,我接收数据,我可以把这些数据放在文本框,richtex但我不能把它们放在数据网格中,实际上我需要把这些数据放在MSSQL中表也可以在数据网格中显示。这是我尝试过的代码:
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;
}
你能帮我填写datagridbiew吗?
这是我获得e.Data的地方:
public class SerialDataEventArgs : EventArgs
{
public SerialDataEventArgs(byte[] dataInByteArray)
{
Data = dataInByteArray;
}
/// <summary>
/// Byte array containing data from serial port
/// </summary>
public byte[] Data;
}
答案 0 :(得分:0)
这是你的答案:
string[] array = imput.split();
当你在str处读取数据时,你在str中有错误是一个数据而不是字符串。
更改此代码:
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);
