While saving password i am encrypting it using the following method:Â
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 using the following code to decode base 64 and quoted printable encoded messages. It works well for all the charset's except for quoted printable chinese (Charsets: GB18030, GB2312). 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 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 RepliesI 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 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)
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. If someone can change the encrypted string and then it decrypts with decrypt function, the decrypted string isn't equal to plain text before encrypting. I want to know how can I check is decrypted string equals to plain text before encrypting?

I am working on a Japanese File and I have no knowledge of the language. The file is encoded in S-JIS. Now, I am supposed to convert the contents into UTF-8 so that the content looks like Japanese. And here I am completely blank. I tried the following code that I found somewhere on Internet but no luck:
byte[] arrByte = Encoding.UTF8.GetBytes(arrActualData[x]);
string str = ASCIIEncoding.ASCII.GetString(arrByte);

Edit I'd misunderstood what was happening here.. there is a POST send, then receive back a result, then the URL string which I'm seeing here is part of the the query string... so I can't decode what this really is, as it is encoded by the payment gateway people and not me.

What is the best way to encode the url in Hyperlink without writing code behind. I have many uses and I would like to do it in the Hyperlink statemeent if possible. Some thing such as the following would be great:
(This does not work)

ID="HyperLink1"
NavigateUrl=
"<%=UrlEncode(~/All_Videos.aspx?tag=full length movie&title=The Movie)%>"runat="server">Movies</asp:HyperLink>
I have a list of character that display fine in WebBrowser in the form of encoded characters such as € � ... But when posting these characters onto server to I realized that HttpUtility.HtmlDecode cannot convert them to characters as browser did, they all become space.
text = System.Web.HttpUtility.HtmlDecode("€");
I expect it to return € but it return space instead. The same thing happen for some other characters as well.
I am trying to render html encoded string that is stored in SQL Server into human readable form. The HttpUtility.Decode does not decode the text that is rendered in between the open tag and closing tag of any input tag (ie. TextBox or TextArea or Select) in my ASPX page. However, HttpUtility.Decode works fine if the text is not in an input tag. The following is my test code. For example, the value of AdmitDX field in database is "Someone's comment" which is "Someone's comment" when decoded. The first two code nuggets <%%> will show as "Someone's comment" and the thrid code nugget will show "Someone's comment".
<!-- the following two lines have html encoded text, instead of html decoded text -->
<%= Html.TextArea("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX))%>
<%= Html.TextBox("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX)) %>
<!-- the next line works fine -->
Test = <%= HttpUtility.HtmlDecode(thisTransfer.AdmitDX) %>

i.e. two identical parts separated by a comma. I'm using a form with both jQuery and UpdatePanel. I've inspected the __VIEWSTATE hidden field before the post __doPostBack and $I.System.InvokePageMethod. In both cases the viewstate does NOT contain the comma. where the field gets doubled up with the comma inserted? Or how to fix.
