This is the compilation error:

0>CustomerDataLoaderFromCsv_csvparse.g.cs(93,9): Error CS0136 : Eine lokale Variable oder ein Parameter namens "next" kann in diesem Bereich nicht deklariert werden, da der Name in einem einschließenden lokalen Bereich zur Definition einer lokalen Variablen oder eines Parameters verwendet wird.
0>CustomerDataLoaderFromCsv_csvparse.g.cs(139,17): Error CS0136 : Eine lokale Variable oder ein Parameter namens "next" kann in diesem Bereich nicht deklariert werden, da der Name in einem einschließenden lokalen Bereich zur Definition einer lokalen Variablen oder eines Parameters verwendet wird.

The problem is that var next for the header isn't scoped and "shadowing" of variables isn't supported in C# (except for lambda expressions).

Hi,

I get an IndexOutOfRangeException in the following line:

} while(rest[end] == '"');

The line is part of the following block:

     if (isQuoted)
    {  
        end = 0;
        var oldEnd = end;
        do{
            if(end>0) {
                replaceDoubleQuotes = true;
            }
            oldEnd = end;
            end = rest[(oldEnd + 1)..].IndexOf(quoteSymbol) + 2 + oldEnd;
        } while(rest[end] == '"');
    }

The reason for this error is a CSV file whose last line doesn't end with a newline character (CR and/or LF).

Hi,

it seems that escaping isn't supported, e.g. "the ""dude""", which should be read as the "dude".

Description

It would be nice if I'd be able to parse a single line. The function signature might look like:

// without options
YourType ParseData(ReadOnlySpan<char> line);

// with options
YourType ParseData(ReadOnlySpan<char> line, Options<char> option);

// without options, but bytes instead of char
YourType ParseData(ReadOnlySpan<byte> line);

// with options, but bytes instead of char
YourType ParseData(ReadOnlySpan<byte> line, Options<char> option);

Reason

• Parallelization of line parsing
• Avoid allocation of List or similar

Other

Maybe support for lines without newline characters could be limited to single line parsing?

Just something minor: The .NET 8 compiler shows the warning CS8826 when the parameter names are different in the users source code and the generated file.

Maybe it's possible to use the same parameter names as in the users source code (e.g. text instead of raw)?
