无法从“System.Collections.ArrayList”转换为Model

[bychgh]

 ArrayList list = new ArrayList();
        for (int i = 0; i < allItems.Length; i++)
        {
            if (!string.IsNullOrEmpty(allItems[i]))
            {
                Model.zcompany zcom = new Model.zcompany();
                zcom.cname = allItems[i];
                zcom.url = "";
                zcom.zid = 1;
                zcom.url ="";
                zcom.beizhu = allItems[i];
                zcom.cid = Convert.ToInt32(this.ddl_city.SelectedItem.Value);
                list.Add(zcom);
            }
        }


        bool flag = combll.Add(list);

报错说 与“BLL.zcompany.Add(Model.zcompany)”最匹配的重载方法具有一些无效参数

参数“1”: 无法从“System.Collections.ArrayList”转换为“Model.zcompany”

但确实有
public void Add(List<Model.zcompany> l)
{
foreach (Model.zcompany model in l)
dal.Add(model);
}
请问怎么解决？

报错说 与“BLL.zcompany.Add(Model.zcompany)”最匹配的重载方法具有一些无效参数 说明你的参数有问题啊！zcom里面的属性类型及属性贴出来看看！

[边城的刀声]

List<Model.zcompany> list = new List<Model.zcompany>();
        for (int i = 0; i < allItems.Length; i++)
        {
            if (!string.IsNullOrEmpty(allItems[i]))
            {
                Model.zcompany zcom = new Model.zcompany();
                zcom.cname = allItems[i];
                zcom.url = "";
                zcom.zid = 1;
                zcom.url ="";
                zcom.beizhu = allItems[i];
                zcom.cid = Convert.ToInt32(this.ddl_city.SelectedItem.Value);
                list.Add(zcom);
            }
        }

帮顶 顺便拿分！！！

ArrayList list = new ArrayList();
变成

List<Model.zcompany> list = new List<Model.zcompany>();

[吴青峰]

IList list = new List<Model.zcompany>();
list.Add(zcom);
试试这个吧

[吴青峰]

改：IList<Model.zcompany> list = new List<Model.zcompany>();
