url decode exception - c#

I have some URL encoded data in a db (sql server 2005) which I decode to parse it. I use:

Uri.UnescapeDataString

sometimes I get:

{"Invalid URI: The开发者_开发知识库re is an invalid sequence in the string."}

what invalid sequences do I have to look out for you reckon?

Thanks.

Have you tried using the HttpUtility.UrlDecode method instead?

As for the "why", perhaps you were running into the .NET 4.0/4.5 issue listed here? Uri.UnescapeDataString fails on different computer

Try this instead.

string decodedUrl = Server.UrlDecode("your-url");

It may possible that your string contain HexEncoded Parameters.

Can you please provide sample string that cause this error.

Thanks, Jinal.
