问题
How can easily encode a string to utf8 using .NET (VB or C#)? For instance I need to encode a string like "This (is) my string" the result should be a string "This+%28is%29+my+string".
TIA

回答1:
This is URL encoding, not UTF8 encoding. Try this method:
HttpUtility.UrlEncode(value)
回答2:
It looks like what you need to do is URL encoding, not "encoding to UTF-8".
For that, use
string encodedString = System.Web.HttpUtility.UrlEncode(yourString)
(UTF-8 is a mechanism for representing Unicode characters internally, not for replacing characters that otherwise have meaning when used in a URI.)
