读取：

var parser = new IniParser.FileIniDataParser();
IniParser.Model.IniData data = parser.ReadFile($"{System.Windows.Forms.Application.StartupPath}\\config.ini");
string bkgmusic = data["system"]["bkgmusic"];

写入：

var parser = new IniParser.FileIniDataParser();
IniParser.Model.IniData data = new IniParser.Model.IniData();
data["system"]["bkgmusic"] = "1";
parser.WriteFile($"{System.Windows.Forms.Application.StartupPath}\\config.ini", data);

C# 每两位插入一个空格

发表评论 
string txt = "12345678" ;
string result = Regex .Replace(txt, @"(\d{2}(?!$))", "$1 " );

每N位插入一个就把2改成N

上面只分操作全是数字的，如果是适应所有的，可以把\d换成 . 号

string txt = "ABCD1E2F4G" ;
string result = Regex .Replace(txt, @"(.{2}(?!$))", "$1 " );
