VB.net .replace start and end of string

Question

I use this to dynamically place the system variable of URL as the class on the body. The problem is that it strips the first trailing '/' and replaces it with a hyphen, which is annoying.

How could I prevent this and just replace the first '/' with nothing?

VB

<body class="<%=Request.ServerVariables("URL").Replace(".aspx","").Replace("/","-")%>">

At the moment if I use:

<body class="<%=Request.ServerVariables("URL").Replace(".aspx","").Replace("/","")%>">

I get something like 'userprofileedit' from a URL of /user/profile/edit

What I actually want is 'user-profile-edit' as a class on my body instead of 'userprofileedit'. My first example:

<body class="<%=Request.ServerVariables("URL").Replace(".aspx","").Replace("/","-")%>">

Does what I need, however I then get a starting hyphen due to the first / from '/user..' - hope this better explains my problem.

Is the / the first character? You could remove it: Request.ServerVariables("URL").Replace(".aspx","").Remove(0, 1) I would highly suggest you put that logic in a function. — the_lotus

You can use Substring(1) to get everything but the first character:

<body class="<%=Request.ServerVariables("URL").Substring(1).Replace(".aspx","").Replace("/","-")%>">

Note: The approach of using Replace to remove the .aspx from the page would also remove it from a folder if it would happen to contain that, but as long as you are aware of that and don't name the folders that way, you're safe.

Is this technically a better way of doing it over the .remove() method above?

@Mat-visual: The difference is very small, but the Substring method is a bit simpler as it gets one part of the string, while the Remove method concatenates two parts of the string (the part before and after the range that you specify).

Use the Remove function to strip off the first character:

<body class="<%=Request.ServerVariables("URL").Replace(".aspx", "").Replace("/", "-").Remove(0, 1)
