VB.Net: UTF-8 Output Should Be ASCII

Posted on 2014-07-21

Good Day Experts!

I have a little VB.Net application that uses the IO.StreamWriter to output data to  .CSV files that we send to the Client.

My feedback from them indicates the files are encoded in UTF-8 and that once converted to ASCII they were able to import.

I have never purposefully sent files encoded in any fashion.  Can you help me understand what I need to do in order to send them ASCII files so they don't have to convert them?

You have to specify the encoding when you create the StreamWriter. Refer the constructor overload with encoding here

Check out the StreamWriter constructor at The second parameter is the encoding. You should be able to use System.Text.ASCIIEncoding.

I took a look at my code and am not sure how to integrate what you have shown me.

Here is what I have:

Public out As IO.StreamWriter
out = My.Computer.FileSystem.OpenTextFileWriter(FileName, False)
out.AutoFlush = True

Do I have to revise my style of coding to incorporate your suggestions?

Thanks again,

out = My.Computer.FileSystem.OpenTextFileWriter(FileName, False)

Open in new window

out = New StreamWriter(FileName, False, Encoding.ASCII)

Open in new window

Hi jimbo99999;

Change this line :

out = My.Computer.FileSystem.OpenTextFileWriter(FileName, False)

To this :

out = My.Computer.FileSystem.OpenTextFileWriter(FileName, False, System.Text.Encoding.ASCII)

You could use at the end of that line System.Text.Encoding.Default because the default encoding using the third parameter is ASCII
