Thought lets share this, we can split large list into multiple lists to process each one separately.

Below function helps to split existing list into multiple, set nSize to any number and it will create lists of same size.

This can be very useful for parallel LINQ.

public static List<List<Class Name>> splitList(List<Class Name> locations, int nSize = 20000)
{
var list = new List<List<Class Name>>();
for (int i = 0; i < locations.Count; i += nSize)
{
list.Add(locations.GetRange(i, Math.Min(nSize, locations.Count - i)));
}
return list;
}
