public static List<T> JSONStringToList<T>(this string JsonStr)

List<T> objs = Serializer.Deserialize<List<T>>(JsonStr);

好了，我们来测试下
string JsonStr = "[{Name:'苹果',Price:5.5},{Name:'橘子',Price:2.5},{Name:'柿子',Price:16}]";
List<Product> products = new List<Product>();
products = JSONStringToList<Product>(JsonStr);
//Response.Write(products.Count());
foreach (var item in products)
{
Response.Write(item.Name + ":" + item.Price + "<br />");
}
public class Product
{
public string Name { get; set; }
public double Price { get; set; }
}
结果：
苹果:5.5
橘子:2.5
柿子:16
