急，RTF的页边距问题
本人用RICTTEXTBOX设置了RTF格式，现在想在打开RTF格式的文档时，页面设置里的页边距的设置以原先的一样，比如说我之前设置了左边距为12.5，那么下一次打开的时候就是12.5，请各位大侠帮忙一下，谢谢！

set { this["RichTextLeftMargin"] = value; }
}
}
}
ProjectSettings setting = new ProjectSettings();
private void button1_Click(object sender, EventArgs e)
{
//读取左边据
Console.WriteLine("左边距:"+setting.RichTextLeftMargin);
}
private void button2_Click(object sender, EventArgs e)
{
//改变并保存
setting.RichTextLeftMargin = 11;
setting.Save();
}
