我有几个来自传感器的数据枚举
time_elapsed,speed_x,speed_y,speed_z,海拔,纬度,经度…
每个列表具有相同数量的元素。
我想将所有列表的数据合并为一系列Status项目。
class Status
{
public int TimeElapsed {get; set; }
public double SpeedX {get; set; }
public double SpeedY {get; set; }
public double SpeedZ {get; set; }
...
}
我考虑过使用Enumerable.Zip方法,但它看起来确实很麻烦:
var statuses = time_elapsed
.Zip(speed_x, (a, b) => new { a, b})
.Zip(speed_y, (c, d) => new { c, d})
.Zip(speed_z, (e, f) => new { e , f})
.Select(x => new Status
{
Time = x.e.c.a,
SpeedX = x.e.c.b,
SpeedY = x.e.d,
SpeedZ = x.f
// ...
});
如您所见,它来自所有这些匿名类型的可读性。
有没有更好的方法来做到这一点而又不失头呢?
最佳答案
您可以在此处执行的操作不多,但是可以提高可读性并删除一种匿名类型:
var statuses = time_elapsed
.Zip(speed_x, (time, speedX) => new {time, speedX})
.Zip(speed_y, (x, speedY) => new {x.time, x.speedX, speedY})
.Zip(speed_z, (x, speedZ) => new Status
{
TimeElapsed = x.time,
SpeedX = x.speedX,
SpeedY = x.speedY,
SpeedZ = speedZ
});
您也可以使用这种方法:
int minSize = new IList[] {time_elapsed, speed_x, speed_y, speed_z}.Min(c => c.Count);
IEnumerable<Status> statuses = Enumerable.Range(0, minSize)
.Select(i => new Status
{
TimeElapsed = time_elapsed[i],
SpeedX = speed_x[i],
SpeedY = speed_y[i],
SpeedZ = speed_z[i],
});
