如何在List中获取数组项 <object> C＃

Question

How to get Array Items inside of List c#

IEnumerable<object> enumerable = c1._getbrandrequest(object[]);

List<object> brand = enumerable.Cast<object>().ToList();

List<Brand> brands = new List<Brand>();

for (int i = 0; i <= enumerable.Count(); i++)
{

    var brnd = enumerable.ElementAt(i);

    // brnd (intellisense only produce)
    // brnd. { Equals, GetHashCode, GetType, ToString }

}

Answer 1

如果enumerable包含Brand对象，那么你需要的是enumerable.ElementAt(i)返回的元素：

var brnd = enumerable.ElementAt(i) as Brand;

Answer 2

I think your code can be a bit cleaner in this way:

IEnumerable<object> enumerable = c1._getbrandrequest(object[]);
List<Brand> brands = enumerable.OfType<Brand>().ToList();

foreach (Brand brnd in brands)
{
  // Do things with brnd.
}

The OfType only returns objects that have a runtime type Brand, and the result is an IEnumerable, the ToList() makes them into a fresh list.

Answer 3

        var enumerable = c1._getbrandrequest( Object[] );

        List<Brand> brands = new List<Brand>();

        foreach (var brnd in enumerable)
        {
            Brand model = new Brand();

            model.sid = brnd.sid;

            brands.Add(model);

        }
