C# 实战串口助手完成！ ----------------------------不竭余力，方能成长！-----------WHAPPY
源码：我会分享开源平台，可以艾特me！（2025/3/5）时间紧张任务中！
文章上所说的串口助手，工程文件资源-CSDN文库
完善功能
代码展示：
DTR功能

}清空计数

}选择路径
private void Select_path_btn_Click(object sender, EventArgs e)
{
FolderBrowserDialog fbDialog = new FolderBrowserDialog();
if (fbDialog.ShowDialog() == DialogResult.OK)
{
Receive_Text_tbx.Text = fbDialog.SelectedPath;
}
}保存数据
private void Save_data_btn_Click(object sender, EventArgs e)
{
if (Receive_rtb.Text == "")
{
return;
}
string fileName = Receive_Text_tbx.Text + "\\" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".txt";
StreamWriter sw = new StreamWriter(fileName);
sw.Write(Receive_rtb.Text);
sw.Flush();
sw.Close();
MessageBox.Show("保存成功！");
}打开文件
private void Open_File_btn_Click(object sender, EventArgs e)
{
OpenFileDialog ofDialog = new OpenFileDialog();
ofDialog.Title = "请选择文件";
ofDialog.Filter = "文本文件(*.txt)|*.txt";
ofDialog.RestoreDirectory = true;

// string select
Send_File_btn.Text = fileName;
StreamReader sr = new StreamReader(fileName, Encoding.GetEncoding("gb2312"));
strRead = sr.ReadToEnd();

}
}发送文件
private void Send_File_btn_Click(object sender, EventArgs e)
{
if (strRead == "")
{
MessageBox.Show("请先选择文件！");
return;
}
try
{
byte[] data = Encoding.GetEncoding("gb2312").GetBytes(strRead);
sendCount += data.Length;
Send_count_tssl.Text = sendCount.ToString();
int pagenum = data.Length / 4096;
int remaind = data.Length % 4096;
for (int i = 0; i < pagenum; i++)
{
serialPort1.Write(data, (i * 4096), 4096);
Thread.Sleep(10);
}
if (remaind > 0)
{
serialPort1.Write(data, (pagenum * 4096), remaind);
}
}
catch (Exception ex)
{
MessageBox.Show("发送数据失败" + ex.Message.ToString(), "错误");
}
}展示效果
完结！ 源码已经开源！！！！！！！
