早上好,
我来自 Python 环境并转向 C#。
我将更宽的列表拆分为具有规定长度的更窄的列表。
有没有办法简化下面的代码?我的猜测是它有点慢,并且没有正确遵循 c# 通用编码规则。
List<object> B = new List<object>();
for(int i = 0; i < SD_Data.Count / 314; i++) {
var SD_Input = SD_Data.Skip(314 * i).Take(314 * i + 313);
B.Add(SD_Input);
}
A = B;
我发现了这个有用的方法
public static IEnumerable<IEnumerable<T>> Chunk<T > (this IEnumerable<T> source, int chunksize)
{
while (source.Any())
{
yield return source.Take(chunksize);
source = source.Skip(chunksize);
}
}
var z = Chunk(x, 10);
但它确实引发了以下错误:

我正在研究 McNeel 的 Rhinoceros 软件的 Grasshopper 界面。
提前致谢!
