大佬们，帮忙指点一下，如何遍历控件NumericUpDown的值    保存到ini，   或者写入序列化，读取反序列化

我现在用的保存Value的值到ini，有N个Value的值，就要敲 N行代码，numericUpDown1.Value  =  ;  想的是能不能用一行代码完成，保存整个窗体的值到XML 或者 ini 里面

现在我是这样保存数据的，
            string S1 = E1_HmoeMode.Text;
            string S2 = E1_HomeHith.Text;
            string S3 = E1_HomeLow.Text;
            string S4 = E1_ValueAbs1.Text;
            string S5 = E1_ValueAbs2.Text;
            string S6 = E1_ValueAbs3.Text;
            string S7 = E1_ValueAbs4.Text;
            string S8 = E1_JogSpeed.Text;
            IniFunc.writeString("Information", "1", S1, filename);
            IniFunc.writeString("Information", "2", S2, filename);
            IniFunc.writeString("Information", "3", S3, filename);
            IniFunc.writeString("Information", "4", S4, filename);
            IniFunc.writeString("Information", "5", S5, filename);
            IniFunc.writeString("Information", "6", S6, filename);
            IniFunc.writeString("Information", "7", S7, filename);
            IniFunc.writeString("Information", "8", S8, filename);


这个是读取数据的
            string S1 = IniFunc.getString("Information", "1", null, filename);
            string S2 = IniFunc.getString("Information", "2", null, filename);
            string S3 = IniFunc.getString("Information", "3", null, filename);
            string S4 = IniFunc.getString("Information", "4", null, filename);
            string S5 = IniFunc.getString("Information", "5", null, filename);
            string S6 = IniFunc.getString("Information", "6", null, filename);
            string S7 = IniFunc.getString("Information", "7", null, filename);
            string S8 = IniFunc.getString("Information", "8", null, filename);
            E1_HmoeMode.Text  = S1;
            E1_HomeHith.Text  = S2;
            E1_HomeLow.Text   = S3;
            E1_ValueAbs1.Text = S4;
            E1_ValueAbs2.Text = S5;
            E1_ValueAbs3.Text = S6;
            E1_ValueAbs4.Text = S7;
            E1_JogSpeed.Text  = S8;

想实现一行代码保存数据，跟读取

数据没写得进去，大佬
