如何在C＃中将数组转换为List <object>？

Question

如何在C＃中将Array转换为List<object> ？

Answer 1

List<object> list = myArray.Cast<Object>().ToList();

如果数组元素的类型是引用类型，则可以.Cast<object>()因为C＃4添加了接口协方差，即IEnumerable<SomeClass>可以被视为IEnumerable<object> 。

List<object> list = myArray.ToList<object>();

Answer 2

使用构造函数： new List<object>(myArray)

Answer 3

List<object>.AddRange(object[]) should do the trick. It will avoid all sorts of useless memory allocation. You could also use Linq, somewhat like this: object[].Cast<object>().ToList()

Answer 4

The List<> constructor can accept anything which implements IEnumerable, therefore...

        object[] testArray = new object[] { "blah", "blah2" };
        List<object> testList = new List<object>(testArray);

Answer 5

private List<object> ConvertArrayToList(object[] array)
{
  List<object> list = new List<object>();

  foreach(object obj in array)
    list.add(obj);

  return list;
}

Answer 6

如果数组项和列表项相同

List<object> list=myArray.ToList();

Answer 7

Everything everyone is saying is correct so,

int[] aArray = {1,2,3};
List<int> list = aArray.OfType<int> ().ToList();

would turn aArray into a list, list. However the biggest thing that is missing from a lot of comments is that you need to have these 2 using statements at the top of your class

using System.Collections.Generic;
using System.Linq;

I hope this helps!

Answer 8

您还可以直接使用数组初始化列表：

List<int> mylist= new List<int>(new int[]{6, 1, -5, 4, -2, -3, 9});

Answer 9

其他方式

List<YourClass> list = (arrayList.ToArray() as YourClass[]).ToList();

Answer 10

这允许您发送一个对象：

private List<object> ConvertArrayToList(dynamic array)

Answer 11

Here is my version:

  List<object> list = new List<object>(new object[]{ "test", 0, "hello", 1, "world" });

  foreach(var x in list)
  {
      Console.WriteLine("x: {0}", x);
  }

Answer 12

You can try this,

using System.Linq;
string[] arrString = { "A", "B", "C"};
List<string> listofString = arrString.OfType<string>().ToList();

Hope, this code helps you.
