How to add List<> to a List<> in asp.net
提问by HasanG
Is there a short way to add List<> to List<> instead of looping in result and add new result one by one?
是否有一种简短的方法可以将 List<> 添加到 List<> 而不是在结果中循环并一个一个地添加新结果？
var list = GetViolations(VehicleID);
var list2 = GetViolations(VehicleID2);
list.Add(list2);

Use List.AddRange(collection As IEnumerable(Of T))method.
使用List.AddRange(collection As IEnumerable(Of T))方法。
It allows you to append at the end of your list another collection/list.
它允许您在列表的末尾附加另一个集合/列表。
Example:
例子：
List<string> initialList = new List<string>();
// Put whatever you want in the initial list
List<string> listToAdd = new List<string>();
// Put whatever you want in the second list
initialList.AddRange(listToAdd);
