%20 在我的 ASP.Net Mvc 中的 URL 中

Question

I have such Url: /%20Account/%20LogOn?ReturnUrl=%2f+Admin%2f+Index

I have two questions:

1)Why I have %20 before Account and LogOn ? Is it something like spaces?

2)How to remove %20 before Account and LogOn ?

Maybe something wrong with Routes?

It's my class RegisterRoutes:

public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");


        routes.MapRoute(
            null, 
            "", 
            new { controller = "Product", action = "List",category = (string)null,page=1 }) ;

        routes.MapRoute(null,
            "Page{page}", 
            new { controller = "Product", action = "List",category = (string)null });

        routes.MapRoute(
            null,
            "{category}",
            new { controller = "Product", action = "List", page = 1 });

        routes.MapRoute(
           null,
           "{category}/Page{page}",
           new { controller = "Product", action = "List"});

        routes.MapRoute(null, " {controller}/ {action}");

    }

Answer 1

Because your url contains white space between words,

For example when you enter this (' somesite.com/some thing ') address in your browser, your browser encode that address to 'somesite.com/some%20thing'

then to decode your URL in code behind, you can use Server.UrlDecode("someURL")

1)Why I have %20 before Account and LogOn? Is it something like spaces?

This is because you have space inside the URL string. Those are converted into encoded string which for the same is %20

2)How to remove %20 before Account and LogOn?

You need to create a link without a space before Account and LogOn. If you are using Html Helper to create the link, you may have not noticed a space before the string of the action.

Answer 3

1) That is the encoded URL .

2) Not sure in what context you are using it but you can decode it using Server.UrlDecode("string")

Answer 4

I had a similar problem in my application, where %20 appears at the end of the url. I had to use .Trim() in order to remove the space before I pass in the required id.

 @Html.ActionLink("Details", "Details", new { id = item.ID_NO.Trim()})

and that solved my problem.
