这是一个 HelperExtension 解决数组和 IEnumerable 属性的麻烦:
public static class AjaxHelperExtensions
{
public static MvcHtmlString ActionLinkWithCollectionModel(this AjaxHelper ajaxHelper, string linkText, string actionName, object model, AjaxOptions ajaxOptions, IDictionary<string, object> htmlAttributes)
{
var rv = new RouteValueDictionary();
foreach (var property in model.GetType().GetProperties())
{
if (typeof(ICollection).IsAssignableFrom(property.PropertyType))
{
var s = ((IEnumerable<object>)property.GetValue(model));
if (s != null && s.Any())
{
var values = s.Select(p => p.ToString()).Where(p => !string.IsNullOrEmpty(p)).ToList();
for (var i = 0; i < values.Count(); i++)
rv.Add(string.Concat(property.Name, "[", i, "]"), values[i]);
}
}
else
{
var value = property.GetGetMethod().Invoke(model, null) == null ? "" : property.GetGetMethod().Invoke(model, null).ToString();
if (!string.IsNullOrEmpty(value))
rv.Add(property.Name, value);
}
}
return System.Web.Mvc.Ajax.AjaxExtensions.ActionLink(ajaxHelper, linkText, actionName, rv, ajaxOptions, htmlAttributes);
}
}
