推荐答案

如果午餐时间列表中没有包含时间，可能最简单（也是最清晰的方法）是只插入预告片。例如：

Probably the simplest (and clearest way) is to only insert into the trailers if the time is not contained in the list of lunchtimes. For example:

var timesToAvoid = (List<string>)dataGridView2.DataSource;
var trailers = new List<trailer__time>();
for (var i = 0; i < trailer_count; i++)
{
    calculated_start_time = calculated_start_time.AddMinutes(i == 0 ? 0 : minutes_apart);

    if (!timesToAvoid.Contains(calculated_start_time.ToString("HH:mm")))
    {
        trailers.Add(new trailer__time
        {
            Trailer_Number = i,
            Delivery_Time = calculated_start_time.ToString("HH:mm")
        });
    }
}

dataGridView1.DataSource = trailers;

如果dataGrideView1只列出了潜在的交付时间而不是trailer_number，那么使用Except方法会更简单...

If dataGrideView1 only listed the potential delivery times and not the trailer_number as well, it would be even simpler by using the Except method...

var timesToAvoid = (List<string>)dataGridView2.DataSource;
var altMethod = new List<string>();
  for (var i = 0; i < trailer_count; i++)
  {
      calculated_start_time = calculated_start_time.AddMinutes(i == 0 ? 0 : minutes_apart);
      altMethod.Add(calculated_start_time.ToString("HH:mm"));
  }
  dataGridView1.DataSource = altMethod.Except(timesToAvoid);
