如何返回空列表对象

I want to return an empty List of type filters thats part of my webservice. When my page loads it doesn't have checkboxes selected so I need to return an empty List

我想返回一个空的List类型过滤器,它是我的webservice的一部分。当我的页面加载时,它没有选中复选框,所以我需要返回一个空列表

public class ProductsAndFilters 
{
    public List<Filter> Filters {get; set; }
    public List<Product> Products {get; set; }
}


public ProductsAndFilters GetProductsAndFilters(json data)
{

    ProductsAndFilters pf = new ProductsAndFilters();
    pf.Products = products;
    pf.Filters = empty filters list here 
    return pf; 
} 

2 个解决方案

#1

just set

pf.Filters = new List<Filter>();

#2

new List<Filter>(); should work.

新列表 ();应该管用。
