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");
cs
/// <summary>
/// 配置文件读写类，支持中文和注释保留
/// 增加备注
/// </summary>
