Convert Text In Textbox To Ascii?

Mar 10, 2010

In .net streams are by default encoded in utf-8. so what i want to do is to simply read the text in a textbox in which i paste the russian characters and then convert them to ascii. but when i debug the code then in my resulting string ? appears. how i can convert the string into its ascii equivalent. my code is given below

string inputString = txtName.Text;
ASCIIEncoding ascii = new ASCIIEncoding();
Encoding encoder = ASCIIEncoding.GetEncoding("us-ascii", new EncoderReplacementFallback(string.Empty), new DecoderExceptionFallback());
byte[] bAsciiString = encoder.GetBytes(inputString);
string cleanString = ascii.GetString(bAsciiString);

I am outputing a text file of 1s and 0s. I want to shrink the file so I'm going to convert it to ascii. Its going to be used on a clientside web application so I can convert it back to binary with some scripting later on.

So, I want to convert the string of binary to a string of ascii serverside in vb.net. I have spent much time searching the web for a vb.net solution, and, what a mess!! everyone thinks they know how to do it, but none of the solutions have worked so far!!

Manually Converting Between ASCII And Net Characters?

Feb 5, 2010

I am working on writing some code to scrub user input to my ASP.NET site. I need to scrub input to remove all references to ASCII characters 145, 146, 147, 148 which are occasionally getting input from my mac users who are copying and pasting content they write in a word processor on their macs.

My issue is the following three strings I am led to believe should output the same text.

string test1 = Convert.ToChar(147).ToString();
string test2 = String.Format("'{0}'", Convert.ToChar(147));
char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[] { 147 });
string test3 = new string(characters);

Yet when I set an ASP TextBox to equal the following

txtShowValues.Text = test1 + "*" + test2 + "*" + test3;

I get a blank value for test1, test2 works correctly, and test3 outputs as a '?'.

Can someone explain what is happening differently. I am hoping this will help me understand how .NET is using ASCII values for characters over 128 so that I can write a good scrubbing script.

EDIT
The values I mentioned (145 - 148) are curly quotes. So single left, single right, double left, double right.

By "works correctly" I mean it outputs a curly quote to my browser.

SECOND EDIT
The following code (mentioned in an answer) outputs the curly quotes as well. So maybe the problem was using ASCII in test 3.

char[] characters2 = System.Text.Encoding.Default.GetChars(new byte[] { 147 });
string test4 = new string(characters2);

THIRD EDIT
I found a mac that I could borrow and was able to duplicate the problem. When I copy and paste text that has quote symbols in them from Word into my web app on the mac it pastes curly quotes (147 and 148). When I hit save curly quotes are saved to the database, so I will use the code you all helped me with to scrub that content.

FOUTH EDIT
Spent some time writing more sample code based on the responses here and noticed it has something to do with MultiLine TextBoxes in ASP.NET. There was good info here, so I decided to just start a new question: http://stackoverflow.com/questions/2215547/asp-net-multiline-textbox-allowing-input-above-utf-8

I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

Web Forms :: TextBox: OnTextChanging / User Is Clearing The Text, If The Length Of Text Becomes Zero?

I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
