                {

                    //存储子菜单值（ＤＬＬ）

                    string[] value = values.GetValues(i);

                    //添加引用

                    assembly = System.Reflection.Assembly.LoadFile("d:/" + value[0]);

                    //读取相应的命名空间和类

                }

                tsi.Text = (values1.GetValues(ii))[0];

                this.menuStrip1.Items.Add(tsi);

            }

            生成个菜单项实例，作为主菜单项。

            //ToolStripMenuItem tsi = new ToolStripMenuItem();

            //System.Reflection.Assembly assembly = null;

            存放读取的INI文件内容

            //string value = "";

            读取INI文件

            //value = iniRead("MENU", "TEST1", "d:/ERP.ini");

            添加引用

            //assembly = System.Reflection.Assembly.LoadFile("d:/" + value);

            创建实例

            //AppForm = (Control)assembly.CreateInstance("ctlMenu.uControl1");

            将DLL中的MenuStrip作为单个菜单项

            //ToolStripMenuItem tsitem = (ToolStripMenuItem)(((MenuStrip)AppForm.Controls[0]).Items[0]);

            将菜单项放入子菜单中

            tsi.DropDownItems.Add(((MenuStrip)AppForm.Controls[0]).Items[0].Text.ToString());

            //tsi.DropDownItems.Add(tsitem);

            //tsi.Text = "MENU";

            //this.menuStrip1.Items.Add(tsi);

        }

        //读取指定INI文件

        private string ReadString(string Section, string Ident, string Default, string path)

        {

            Byte[] Buffer = new Byte[65535];

            int bufLen = GetPrivateProfileString(Section, Ident, Default, Buffer, Buffer.GetUpperBound(0), path);

            //必须设定0（系统默认的代码页）的编码方式，否则无法支持中文

            string s = Encoding.GetEncoding(0).GetString(Buffer);

            s = s.Substring(0, bufLen);

            return s.Trim();

        }

        private void GetStringsFromBuffer(Byte[] Buffer, int bufLen, StringCollection Strings)

                for (int i = 0; i < bufLen; i++)

                {

                    if ((Buffer[i] == 0) && ((i - start) > 0))

                    {

                        Strings.Add(s);

                        start = i + 1;

                    }

                }

            Byte[] Buffer = new Byte[16384];

            int bufLen = GetPrivateProfileString(Section, null, null, Buffer, Buffer.GetUpperBound(0), PATH);

            //对Section进行解析

            GetStringsFromBuffer(Buffer, bufLen, Idents);

        }

        //读取指定的Section的所有Value到列表中

        {

            StringCollection KeyList = new StringCollection();

            ReadSection(Section, KeyList);

            Values.Clear();

            foreach (string key in KeyList)

            {

                Values.Add(key, ReadString(Section, key, "", PATH));

            }

        }

        private void ddToolStripMenuItem_Click(object sender, EventArgs e)

        {

            //Form2 frm2 = new Form2();

            //string value = "";

            读取INI文件

            //value = iniRead("MENU", "TEST1", "d:/ERP.ini");

            加引用

            //Assembly ass = Assembly.LoadFrom("d:/" + value);

            取类的类型

            //Type type = ass.GetType("ctlMenu.uControl1");

            实例此类

            //Object obj = Activator.CreateInstance(type);

            获取此类的方法，frmShow为类的方法名称

            //MethodInfo mi = type.GetMethod("frmShow");

            //Object[] obj1 ={ (Object)frm2 };

            //frm2.MdiParent = this;

            使用方法

            //mi.Invoke(obj, obj1);

        }

    }
