在winform应用里，有DataGridView，用BindingList 做数据源。

MotionList = new List<Motion>();
MotionBList = new BindingList<Motion>(MotionList);
DataGridViewMotion.DataSource = MotionBList;
DataGridViewMotion.RowHeadersVisible = false;
DataGridViewMotion.AllowUserToAddRows = false;
DataGridViewMotion.ReadOnly = true;

Where

public class Motion
{
    public string StartTime { get; set; }
    public string EndTime { get; set; }
    public string StartPos { get; set; }
    public string EndPos { get; set; }
}

用 MotionBList.Add() MotionBList.RemoveAt() 这两方法来更新DataGridViewMotion. 只有如下用法，都用SyncContext在UI线程执行了：

SyncContext = WindowsFormsSynchronizationContext.Current;

SyncContext.Post(new SendOrPostCallback((_) =>
{
    if (MotionBList.Count > 600)
    {
        for (int i = 0; i < 100; i++)
        {
             MotionBList.RemoveAt(0);
        }
    }
    MotionBList.Add(MakeMotion(...));
}), null);

private Motion MakeMotion(string a, string b)
{
    return new Motion() {StartPos = a, EndPos = b};
}

大部分时候都正常工作，但是 MotionBList.Add(MakeMotion(...))时有小概率报错, 报错信息如下：

Application_ThreadException System.ArgumentOutOfRangeException： 107 的值对于 indexStart无效, indexStart 必须小于等于 93.

上面的异常是 Programe.cs 里的代码捕获到的

Application.ThreadException += Application_ThreadException;  //只捕获UI线程的错误
private static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
{
   MessageBox.Show($"Application_ThreadException {e.Exception}");
}
