I have a string like

select * from Contacts where lastname='test';

when I'm use urlencode method from php, i get a result

select+%2A+from+Contacts+where+lastname%3D%27test%27%3B

My question is, how to do the same thing with C#, i have tried

HttpUtility.UrlEncode("select * from Contacts where lastname='test';", Encoding.ASCII)

HttpUtility.UrlEncode("select * from Contacts where lastname='test';")

and the result is

select+*+from+Contacts+where+lastname%3d%27test%27%3b

Why you need to encode query?! If you are passing it via query string, it's a bad idea.

I don't tried to encode a sql query via query string :) If I want to pass the query string, I can create an property to handle that :)

Have you tried just HttpUtility.UrlEncode(...) (no second parameter)

I also tried that, the second parameter to make sure it use ASCII :) thanks for your quick answer :)

It was a bit of an off-the-cuff answer since we use it that way and I can't recall experiencing the same issue recently. Obviously there's more to the story.
