Re: Text conversion - C# Discussion Boards

Hi All

I've got some problems with converting readed text from *.doc file. I'm using this code:

FileStream fs = null;
 
fs = new FileStream(plik.ToString(), FileMode.Open);
byte[] example = new byte[fs.Length];
fs.Read(example, 0, example.Length);
string outtext = "";
int count = 0;
 
for (int i = 2560; i < example.Length; i++)
{
        if (example[i] == 0)
        {
                break;
        }
        count++;
}
 
BinaryReader br = new BinaryReader(fs, Encoding.GetEncoding(1250));
br.BaseStream.Position = 2560;  
byte[] newarr = br.ReadBytes(count); 
 
outtext = System.Text.UTF8Encoding.UTF8.GetString(newarr); 
string str = "";
for (int i = 0; i < outtext.Length; i++)
{
        if ((outtext[i] >= '!' && outtext[i] <= '~') || (outtext[i] == ' ') || (outtext[i] == '\r'))
        {
                str += outtext[i];
        }
}
fs.Close();
tekst = str;

It works great till I try to read file with polish symbols (ISO-8859-2). I try'ed to convert it to ISO-8859-2 but it is not working propertly.

Could anybody help me with this problem?

"Windows-1250 is similar to ISO-8859-2 and has all the printable characters it has and more. However a few of them are rearranged (unlike Windows-1252, which keeps all printable characters from ISO-8859-1 in the same place). Most of the rearrangements seem to have been done to keep characters shared with Windows-1252 in the same place as in Windows-1252 but three of the characters moved (Ą,Ľ,ź) cannot be explained this way."

I'd suggest you use "ISO-8859-2" as your encoding to read the file, not Windows-1250.

Thanks for post but as I can read at this site, I'm using ISO-8859-2 encription: http://msdn.microsoft.com/en-us/library/system.text.encoding.codepage.aspx[^]

Am I right? How can I do this encription in other way?

Not in the code you posted;

BinaryReader br = new BinaryReader(fs, Encoding.GetEncoding(1250));

If you read them in the correct format and save them as UTF8, you should not see a loss of information.

As You told me I convert sorce data to iso-8859-2 and then to UTF-8, but the result was the same. If I convert english docs it works perfect, but when I use polish docs i get this result string: "."

There's solution that I create for this:

FileStream fs = null;
				try
				{
					fs = new FileStream(plik.ToString(), FileMode.Open);
					byte[] example = new byte[fs.Length];
					fs.Read(example, 0, example.Length);
					string outtext = "";
					int count = 0;
					
					for (int i = 2560; i < example.Length; i++)
					{
						if (example[i] == 0)
						{
							break;
						}
						count++;
					}
					
					BinaryReader br = new BinaryReader(fs, Encoding.GetEncoding("iso-8859-2"));
					br.BaseStream.Position = 2560;
					byte[] newarr = br.ReadBytes(count);
					outtext = System.Text.UTF8Encoding.UTF8.GetString(newarr);
					string str = "";
					                                   
					for (int i = 0; i < outtext.Length; i++)
					{
						if ((outtext[i] >= '!' && outtext[i] <= '~') || (outtext[i] == ' ') || (outtext[i] == '\r'))
						{
							str += outtext[i];
						}
					}
					fs.Close();
					tekst = str;
				}
				catch (Exception exc)
				{
					Console.WriteLine(exc.ToString());
					return;

}

So could anybody give me any other advice?

Aight, let's take a look at this piece of the code;

BinaryReader br = new BinaryReader(fs, Encoding.GetEncoding("iso-8859-2"));
br.BaseStream.Position = 2560;
byte[] newarr = br.ReadBytes(count);
outtext = System.Text.UTF8Encoding.UTF8.GetString(newarr);

You are reading the file as an array of bytes - those values won't change based on the encoding. Once you convert it to a string, it'll have to know what encoding to use to convert those bytes into the correct character. That's what your last line is doing, but it is using the UTF8-encoding - not your iso-8859-2. Hence, the system will interpret those bytes that you just read as UTF8.

Read them as the iso-format, and all should work.

I used:

outtext = Encoding.GetEncoding("iso-8859-2").GetString(newarr);

but it's not working. Where should I use this encription?

Eddy Vluggen4-Jul-12 3:05

It's not an encryption, but an encoding. Below example should work, tested it with the Polish Army Oath from the Wikipedia;

public static void Main (string[] args)
{
	Encoding enc = Encoding.GetEncoding("iso-8859-2");
	string someString = File.ReadAllText("test.txt", enc);
	Console.WriteLine (someString);
}

Thanks, but I know this type of encoding. I just don't know how to use it with binaryreader that I need to use.

how to get a ressource folder into the in folder

4-Jul-12 3:27

Why do you "need" to read it as binary and convert it to string, when you can read it as a string?

There's an example[^] on MSDN that shows how to use the encoding with a array of bytes.

Hello

I need to have a ressource folder automaticaly created into the bin folder by the compiler and automaticaly copy a text file in it

Purpose :
My application need to read some information into a predefined textfile
I can obviously create that text file into the ressouce folder of the project

But when I compile the project I need that this text file will be automaticaly copied into the ressouce folder in the Bin Folder

What is the method to do that ?
Thanks a lot for your help

You could include the file and go to the properties page and select "Always copy", or create a batch-file and execute that prior to build. Remember that the IDE can execute commands before build, is somewhere in the projects' settings.

Thank You !

"Always copy" is the tip !!

in some IDE's (such as Visual Studio) you can specify pre-build and post-build commands; these get executed at the start and termination of a build, and use a DOS-like syntax. Copying some files in this way is a typical usage.

OTOH if your files are present while building, what makes you think they will disappear? You can add all kinds of files to a project, and get them deployed. Again, VS gives you a choice of actions to be taken for files it doesn't normally know about, the choices are: none, compile, content, embedded resource. I suggest you experiment a little.

It descibes how to use the FB ads api.

The documentation is language-agnostic. If you need a third-party wrapper that talks from C# to FB on your behalf, have a look at the Facebook SDK[^].
