Read all ini file values with GetPrivateProfileString

Question

I need a way to read all sections/keys of ini file in a StringBuilder variable:

[DllImport(\"kernel32.dll\")]
private static extern int GetPrivateProfileStri         


        

Answer 1

These routines will read an entire INI section, and either return the section as a collection of raw strings where each entry is a single line in the INI file (useful if you're using the INI structure but don't necessarily have an =), and another that returns a collection of keyvalue pairs for all of the entries in the section.

    [DllImport("kernel32.dll")]
    public static extern uint GetPrivateProfileSection(string lpAppName, IntPtr lpReturnedString, uint nSize, string lpFileName);

    // ReSharper disable once ReturnTypeCanBeEnumerable.Global
    public static string[] GetIniSectionRaw(string section, string file) {
        string[] iniLines;
        GetPrivateProfileSection(section, file, out iniLines);
        return iniLines;
    }

    /// 
 Return an entire INI section as a list of lines.  Blank lines are ignored and all spaces around the = are also removed. 
    /// [Section]
    /// INI File
    ///  List of lines 
    public static IEnumerable> GetIniSection(string section, string file) {
        var result = new List>();
        string[] iniLines;
        if (GetPrivateProfileSection(section, file, out iniLines)) {
            foreach (var line in iniLines) {
                var m = Regex.Match(line, @"^([^=]+)\s*=\s*(.*)");
                result.Add(m.Success
                               ? new KeyValuePair(m.Groups[1].Value, m.Groups[2].Value)
                               : new KeyValuePair(line, ""));
            }
        }

        return result;
    }
