Ini配置文件读写,增加备注功能

1.增加备注项写入

例:

#节点备注
[A]
#项备注
bbb=1
ccc=2

[B]
bbb=1

 IniConfig2 ic = new IniConfig2();

//首次写入

            if (!ic.CanRead())
            {
                ic.AddSectionReMarke("A", "节点备注");
                ic.SetValue("A", "bbb", "1" );
                ic.SetValue("A", "ccc", "2");
                ic.SetValue("A", "ccc", "2");
                ic.SetValue("B", "bbb", "1");
                ic.AddItemReMarke("A","bbb", "项备注");
            }

//获取值

        string a = ic.GetValue("A", "bbb");
