StreamReader Question

[atmosphere1212]

Hey,

 

Im reading in characters of text, one by one, and I want to replace any odd characters of text (above ascii 128) with spaces.

 

However.. when i use

 

someInt = myStreamReader.Read

 

It seems to completely skip over these odd characters.. How can I read these characters?

try using a binary reader. basically, a class that derives from Stream

This doesnt work either. Heres my code

 

           Dim curChar As Integer = bStream.Read()

           While curChar <> 13 And curChar <> 26 And curChar <> -1
               curLine += Chr(stripErrorChars(curChar))
               curChar = bStream.Read
           End While

 

That was the code which reads a line of text. The following is the stripErrorChars method

 

       Private Function stripErrorChars(ByVal curChar As Integer) As Integer

           If curChar = 0 Then
               Return 32
           ElseIf curChar >= 128 Then
               Return 32
           Else
               Return curChar
           End If

       End Function

What kind of encoding does the text file use? If the data is stored using unicode then you cannot assume each byte represents one character in that manner.

 

You may be better of using something like System.Text.ASCIIEncoding to convert the data to an ASCII based output instead.

i've never seen a class that derives from system.io.stream that has a read method that takes no parameters.

 

you're probably using the BinaryReader class which is not derived from system.io.stream and if so, maybe that's your mistake.

 

The encoding will matter if it's unicode16 or higher.

Different encodings are not just a problem with UTF-16, there are various Double Byte encodings (e.g. Shift_JIS), UTF-8 is a Multi-Byte encoding format as well.
