StreamReader from .csv - "foreign" chars and blank values showing up as '?'

I'm having two problems with reading my .csv file with streamreader. What I'm trying to do is get the values, put them into variables which I'll be using later on, inputting the values into a browser via Selenium.
Here's my code (the Console.Writeline at the end is just for debugging):
string[] read;
char[] seperators = { ';' };
StreamReader sr = new StreamReader(#"C:\filename.csv", Encoding.Default, true);
string data = sr.ReadLine();
while((data = sr.ReadLine()) != null)
{
read = data.Split(seperators);
string cpr = read[0];
string ydelsesKode = read[1];
string startDato = read[3];
string stopDato = read[4];
string leverandoer = read[5];
string leverandoerAdd = read[6];
Console.WriteLine(cpr + " " + ydelsesKode + " " + startDato + " " + stopDato + " " + leverandoer + " " + leverandoerAdd);
}
The code in and of itself works just fine - but I have two problems:
The file has values in Danish, which means I get åøæ, but they're showing up as '?' in console. In notepad those characters look fine.
Blank values also show up as '?'. Is there any way I can turn them into a blank space so Selenium won't get "confused"?
Sample output:
1372 1.1 01-10-2013 01-10-2013 Bakkev?nget - dagcenter ?
Bakkev?nget should be Bakkevænget and the final '?' should be blank (or rather, a bank space).

"Fixed" it by going with tab delimited unicode .txt file instead of .csv. For some reason my version of excel doesn't have the option to save in unicode .csv...
Don't quite understand the problem of "rolling my own" parser, but maybe someday someone will take the time to explain it to me better. Still new-ish at this c# stuff...

C# move path includes invalid characters

I've been trying to do a renamer program in c# for 2 different paths and I keep getting error "Path includes invalid characters" I have no clue how to fix it, I've tried adding # and deleting \ and keeping only one . But still didn't figure out how to fix it. Would love any help.
This is what gives me an error:
if (French.Checked)
{
directoryfile = #"C:\Users\" + curruser + #"\Appdata\Local\fo4renamer\directory.txt";
label1.Text = directoryfile;
readpath = File.ReadAllText(directoryfile);
string shouldwork = readpath + "data";
string french = shouldwork + "\\french";
string german = shouldwork + "\\german";
string tmp = shouldwork + "tmp.txt";
label1.Text = french;
string path2 = #"C:\Users\duchacekda\Desktop\e\Renamer\Renamer\bin\Debug\tmp.txt";
string filename = #"C:\Users\duchacekda\Desktop\e\Renamer\Renamer\bin\Debug\french.txt";
File.Move(french, german);
}
Here is the whole code:
https://pastebin.com/0i7fzh24
Edit: this is the string for curruser
string curruser = System.Environment.UserName;
The exception was given by this line
File.Move(french, german);

File.ReadAllText Method (String) : Opens a text file, reads all lines of the file, and then closes the file.
So in your scenario :
string french = (Content of directory.txt) + "data" + "\\french";
It depends on content of directory.txt
a) If content = directory path(c:\foo) there is no problem
b) if content = "dummy text *** dummy text" then it will throw exception
Please check content of file

Found the mistake, I used WriteLine instead of Write so it added enter on the end of the line which made the path incorrect, thanks for the help

Split a line/sentence in two in C#

How can I split different part of a sentence in a text file and put each part where I want?
I have this in a text file:
Marc;260.65
Sonia;450.37
Richard;195.00
Bob;50.00
Paul;789.00
I want to read the file using StreamReader and append the result to be something like this:
Marc, Amount: 260.65 $
Sonia, Amount : 450.37 $
...
Here's my code so far:
StreamReader File1 = new StreamReader("test.txt");
string sSentence = "";
string sAmount = "";
while (!File1.EndOfStream)
{
sSentence = File1.ReadLine();
sSentence.Split(';');
txtResult.AppendText(sSentence + ",sAmount : "+ sAmount + " $"+"\n");
}
Basically I don't know how to associate the number with the variable sAmount to append it properly.

Can you use Replace()?
sSentence.Replace(";", ", Amount: ");

Checking if two strings are equal

I want to check if a string from the first line of a file, is equal with an another string.
The awkward part is that, the strings are the same, but my program doesn't return a true value.
The string is teach and the first line of the file is teach too.
string date = System.IO.File.ReadAllText(folder + "/NPC/" + score_npc + "/" + score_npc + ".txt" );
if (condition)
{
string[] parametrii = date.Split('\n');
if (parametrii[0].Equals("teach"))
//instructions
I tried all the compare methods, i made my own function too. And my function said me that the (parametrii[0])[0] == b
Here is how the file looks like:
teach
poza1
poza2
end

That's propably because new line character is not \n in the file. It may be \r\n instead.
Try File.ReadAllLines instead:
string[] lines = System.IO.File.ReadAllLines(folder + "/NPC/" + score_npc + "/" + score_npc + ".txt" );
if (condition)
{
if (lines[0].Equals("teach"))
// instructions
}
Edit
As Grant Winney suggests, if you only need to manipulate first line (or not all of the) file, you may use File.ReadLines:
string firstLine = File.ReadLines(path).First();
instead.

Have u tried to change
string[] parametrii = date.Split('\n');
into
string[] parametrii = date.Split(Environment.NewLine);?
I suspect it's because your strings contain '\r' character

How can I remove a last part of a string with an unknown int?

So, I'm making a file transfer program from one PC in my house to the other. The client can look through the server's files and take what it wants. (Makes it very easy for moving projects/documents/music). This is an example of what a string of a file looks like:
New Text Document.txt : "(FILE)-(" + f.Length + " Bytes)"
My problem is removing : "(FILE)-(" + f.Length + " Bytes)".
How can I remove JUST that part from the string? Where the f.Length is unknown...
Thanks!

Just as an alternative to the regex answers, one option is to use LastIndexOf to find the last occurence of a known part of the string (e.g. (FILE)).
var oldString = "ThisIsAString (FILE)-(1234 Bytes";
int indexToRemoveTo = oldString.LastIndexOf("(FILE)");
// Get all the characters from the start of the string to "(FILE)"
var newString = oldString.Substring(0, indexToRemoveTo);

I hope I've got what you want
string contents = "some text (FILE)-(5435 Bytes) another text";
string result = Regex.Replace(contents, #"\(FILE\)-\(\d+ Bytes\)", "");
Console.WriteLine (result);
Prints:
some text another text
Solution to remove everything after .txt
string contents = "some text .txt (FILE)-(5435 Bytes) another text";
string lastSegment = ".txt";
var result = contents.Substring(0, contents.IndexOf(lastSegment) + lastSegment.Length);
Console.WriteLine (result);
prints some text .txt

var match = Regex.Match(pattern: #"\((.*)\)-\(\d+ Bytes\)$", input: name);
if(match.Success)
{
string fileName = match.Groups[1].Value;
}
