Hello
This is suppose to be simple but I can't get it to work:

Imports System.Web.HttpServerUtility

s ="This is a <Test String>"
lblError.Text = Server.HtmlEncode(s)



I am suppose to get "This+is+a+%3cTest+String%3e" but I get "This is a <Test String>". What am I overlooking??

The string gets encoded as "This is a &lt;Test String&gt;", if you "view source" you will see it. But you will not see that as the label text because when the page renders, it interprets the characters and shows you the original text.

According to MSDN when I use Server.HtmlEncode I am suppose to get "This+is+a+%3cTest+String%3e" not "This is a &lt;Test String&gt;". How can I get "This+is+a+%3cTest+String%3e"???

Below is the link that tells me that "This is a <Test String>" suppose to get "This+is+a+%3cTest+String%3e".

What am I doing wrong???

I am not sure why it doesn't encode that way. The example MSDN gives won't even work, you can't Dim writer As New StringWriter, this gives an error.

Why is this so important to you to get this particular result?

jbenson001,
I see Server.HtmlEncode used to encode URL Strings on most all major websites like Yahoo.com.

Somebody Please help me.

Imports System.Web.HttpServerUtility

Dim TestString As String = "This is a <Test String>."
Dim writer As New StringWriter
Server.HtmlEncode(TestString, writer)
Dim EncodedString As String = writer.ToString()


suppose to yield:This+is+a+%3cTest+String%3e
but I get:This is a <Test String>.

Help!!!!!

Hi ,

Use Urlencode, try this.

string str = "This is a <Test String>.";

Response.Write(str);

string encodedstr = System.Web .HttpUtility .UrlEncode (str.ToString());

Response.Write(encodedstr);

Hello butterfly

I think your C# code translates to this in VB.NET ( I don't know C# at all):
------------------------------------------------------------
 Dim str As String = "This is a <Test String>."

        Response.Write(str)

        Dim encodedstr As System.Web.HttpUtility

        encodedstr.UrlEncode(str)
        Response.Write(encodedstr)
------------------------------------------------------------

When I try this I only get "This is a ."
I don't even see the encoded string.

Please Help

Thanks butterfly it worked.

I have another question.
Originally I was trying to use Server.HtmlEncode for textboxes so I can make the html tag content safe to store in SQL Database.

I was told if I use Server.HtmlEncode that I can avoid SQL Script injections. But I couldn't get Server.HtmlEncode to work.

Is it common practice to use UrlEncode as a substitute for Server.HtmlEncode to avoid SQL Script Injections??

What is the difference between UrlEncode and HtmlEncode???

I am very new to ASP.NET.

One final question for this topic.

How come when I use UrlDecode I don't get the correct answer?
Instead of getting "This is a <Test String>." I get "This is a ."

Dim encodedstr As System.Web.HttpUtility
        Dim encoded As String
        Dim decode As String


        encoded = encodedstr.UrlEncode("This is a <Test String>.")
        Label2.Text = encoded.ToString

        decode = encodedstr.UrlDecode(encoded)
        Label3.Text = decode

-------------------------------------------------
What am I overlooking???
