使用线程插入数据时引发错误抛出异常

Question

I have probem when use thread in winform. I have error when debug program.

My Application throw exception when start program.

I define class RunInUIThread is:

private void RunInUIThread(Delegate method)
{
    this.BeginInvoke(method);
}

And in RunInUIThread method like:

BaiXeBUS baixe = new BaiXeBUS();
RunInUIThread(new ThreadStart(delegate ()
{
          BaiXeDTO obj = new BaiXeDTO();      //Map all to define database 
          txtKhuVucBai.Text = mReader.CurrentCardIDBlock1.ToString();
          txtMaThe.Text = mReader.CurrentCardIDBlock2.ToString();

          //If I comment all below code. It's work. But I need Insert data to database.
          txtKhuVucBai.Text = obj.IDBaiXe.ToString();
          txtMaThe.Text = obj.IDRF.ToString();
          obj.BienSoXe = textBox1.Text;
          obj.HinhBienSo = color.ToString();
          obj.HinhChuXe = img.ToString();
          obj.ThoiGianVao = DateTime.Now.ToLocalTime();
          obj.ThoiGianRa = DateTime.Now.ToLocalTime();
          baixe.BaiXe_Insert(obj); //Contain data access layer to insert data with store procedure.
}));

Why my code not work. Someone can explain me and how to fix problem? Thank all reader!!!

Answer 1

@JoelLegaspiEnriquez, your recommned me to remove [STAThread] in Program.cs?

If I comment this line. This have problem in control AxLiveX1 is control of camera ip.

The txtKhuVucBai.Text = mReader.CurrentCardIDBlock1.ToString(); is Guid type with 16byte: 8d58d690-6b71-4ee8-85ad-006db0287bf1.

But i assign txtKhuVucBai to Guid type is:

private Guid mCurrentCardIDBlock1;
public Guid CurrentCardIDBlock1
{
        get { return mCurrentCardIDBlock1; }
}

The mCurrentCardIDBlock1 is type of RFID reader with 32 character random.

Answer 2

What I mean is trying to run this block of code without the ThreadStart

{
    BaiXeDTO obj = new BaiXeDTO();      //Map all to define database 
    txtKhuVucBai.Text = mReader.CurrentCardIDBlock1.ToString();
    txtMaThe.Text = mReader.CurrentCardIDBlock2.ToString();

    //If I comment all below code. It's work. But I need Insert data to database.
    txtKhuVucBai.Text = obj.IDBaiXe.ToString();
    txtMaThe.Text = obj.IDRF.ToString();
    obj.BienSoXe = textBox1.Text;
    obj.HinhBienSo = color.ToString();
    obj.HinhChuXe = img.ToString();
    obj.ThoiGianVao = DateTime.Now.ToLocalTime();
    obj.ThoiGianRa = DateTime.Now.ToLocalTime();
    baixe.BaiXe_Insert(obj); //Contain data access layer to insert data with store procedure.
}

This is to debug your code within the main thread.
