Hi bekim,

following code works well

string str = "This is a <Test String>.";
TextBox1.Text = str.ToString();
string encodedstr = System.Web.HttpUtility.UrlEncode(str.ToString());
TextBox2.Text = encodedstr.ToString();
string decodedstr = System.Web.HttpUtility.UrlDecode(encodedstr);
TextBox3.Text = decodedstr.ToString();

:)

Hi bekim,

for HtmlEncode, try this

string str = "This is a <Test String>.";
string htmle = System.Web.HttpUtility.HtmlEncode(str.ToString());
TextBox4.Text = htmle.ToString();
string htmld = System.Web.HttpUtility.HtmlDecode(htmle.ToString() );
TextBox5.Text = htmld.ToString();

Difference is when you use urlencode it converts spaces into '+'

when you execute UrlEncode and HtmlEncode for the same string, you can find the difference.

:)

Dear Butterfly,
I think something else is the matter.
When I run:

string str = "This is a <Test String>.";
Response.Write(str);

I get "This is a ." not "This is a <Test String>."

For some reason the "<Test String>" doesn't show.
I even use validaterequest=false at @Page in html part.

What could be the problem??

Hey,

THe string is decoded, so it thinks <Test String> is an HTML element. If you view source, you will see it. If you want it rendered appropriately, do:

Response.Write(Server.HtmlEncode(str))

When you render the text as a link, it then should appear appropriately encoded. Did you try adding it as a querystring value and seeing it there? It should something like:

This+is+a+%3cTest+String%3e

But instead of +, you should get %20. However, in your app, if you write to a string, it will appear as you see it.
