I know that I could use HttpServerUtility.UrlTokenDecode Method to do the job. But the problem is that I am using .NET 1.1 and this method is only supported in .NET 2.0+. Also I found that Convert.ToBase64String method is not an option because of the differences addressed here. So what other options do I have? Do I have to write my own converting method?
View 1 RepliesWhile saving password i am encrypting it using the following method:
public string base64Encode(string sData) { try { byte[] encData_byte = new byte[sData.Length]; encData_byte = System.Text.Encoding.UTF8.GetBytes(sData); string encodedData = Convert.ToBase64String(encData_byte); return encodedData; } catch (Exception ex) { throw new Exception("Error in base64Encode" + ex.Message); } }
I am creating a web site in .Net 3.5 , I am converting the string into Base64String to send it through querystring.The Response.Redirect works fine for smaller string. But if the original string size is 1670,the response.redirect results in error "Page can not be found".item is the string in below code snippet.
byte[] data = Encoding.Default.GetBytes(item);
return Convert.ToBase64String(data)

When I tried to decode, I am getting '?' as output. provide on this code or any other code that decodes all types of encoded string?

I encrypt and decrypt a string with a private key and following functions. so I encrypt a string with Encrypt function and decrypt the encrypted string with decrypt function.

I want to know how can I check is decrypted string equals to plain text before encrypting?

I want to make a data url from an existing file on the system.
@Convert.ToBase64String() wil do the trick but how do i convert a 'webimage' to a byte array?
Or is there a project to convert 'anything' to a data uri?
I have to send a file to my webservice, but the webservice assumes the file (byte Array) as a base64Binary.
Before the encoding, the byteArrayFile is saved on disk as a regular File. (I'm doing it just for testing)
So, in my Java client for webservice, I'm sending the information this way:
String file = new sun.misc.BASE64Encoder().encode(byteArrayFile);
port.sendFileToWebService(file);
The webservice have to decode the information and save the received file on disk.

i'm trying to encode an url with the code below;
var encodedUrl = HttpUtility.UrlEncode("http://www.example.com");
var decodedUrl = HttpUtility.UrlDecode("http%3A%2F%2Fwww%2Eexample%2Ecom%2F");
I'm working with the google webmaster tools api and this api expects an URL as shown in the decodedUrl variable above. Every single character is encoded there.
When i use the httputility encode function i get the following result;[[URL] How can i use the encoding variable in such a way that every character in the url is encoded?
The URL link below will open a new Google mail window. The problem I have is that Google replaces all the plus (+) sign in the email body with blank space. It looks like it only happens with the + sign. ( I am working the ASP.NET web page)

When storing a value in a cookie using C#, what is the best way to encode (or escape) the value so that it can be retrieved and decoded/unescaped reliably?
I'm not talking about encryption.
I want to reliably and easily Uri encode paths such as "/folder/foo%bar" to "/folder/foo%25bar".
I would have hoped that HttpUtility.UrlPathEncode would do the trick but this method only escapes spaces. I don't want to url HttpUlity.UrlEncode as this will encode "foo bar" to "foo+bar" - which ain't what I want.

Have an issue with the HTML editor. Whenever somebody uses an apostophe ( ' ) in the editor and then clicks save (which will send an update to the database) it is taking the apostrophe as part of my command line and it is returning an error. I used a replace to change the apostophe into an encoded html tag but then it was changing it for all the <div> and <span> created by the editor which was causing none of the code to work. how I can encode the apostrophe without encoding the code?
