我想返回一个RedirectToRouteResult,将用户发送到如下所示的URL：
/MyController/MyAction/id?newid=3&newid=5&newid=7
newid参数有几个值.
我的电话看起来像：return RedirectToAction(string.Empty,routeValues);
这是我迄今为止所尝试过的,这不行：
// ...?newid%5B0%5D=3&newid%5B1%5D=5&newid%5B2%5D=7
var routeValues = new RouteValueDictionary {
{"id",myid},{"newid[0]",3},{"newid[1]",5},{"newid[2]",7},};
// ...?newid=System.Int32%5B%5D
var routeValues = new { id = myid,newid = new int[] { 3,5,7 } };
// ...?newid=System.String%5B%5D
var routeValues = new { id = myid,newid = new string[] { "3","5","7" } };
// ...?newid=System.Int32%5B%5D
var routeValues = new RouteValueDictionary {
{"id",{"newid",new int[] { 3,7 } }
};
使这项工作有什么秘密？
解决方法
这是框架中真正缺失的一件事.你最好的办法是手动滚动它：
public ActionResult Foo()
{
var ids = new[] { 3,7 };
var url = new UriBuilder(Url.Action("MyAction","MyController",new { id = "123" },Request.Url.Scheme));
url.Query = string.Join("&",ids.Select(x => "newid=" + HttpUtility.UrlEncode(x.ToString())));
return Redirect(url.ToString());
}
