动态创建Menu c# ado.net

想动态创建menustrip，下面的代码在form里有用，但是在copy到cs里面却报了4个错， this.Hide();， this.SuspendLayout();， this.Controls.Add(this.menuStrip1);， this.ResumeLayout(false);

``` private void 工序录入ToolStripMenuItem_Click(object sender EventArgs e)
{
工序资料维护 frmGXLR = new 工序资料维护();
frmGXLR.Show();
this.Hide();

    }    private void 录入ToolStripMenuItem1_Click(object sender EventArgs e)    {        中小修管理录入 frmZXXGLLR = new 中小修管理录入();        frmZXXGLLR.Show();        this.Hide();    }    //动态创建menuSctrip    private void addMenuSctrip()    {             this.menuStrip1 = new System.Windows.Forms.MenuStrip();        this.文件ToolStripMenuItem = new System.Windows.Forms.ToolStripMenuItem();                        this.menuStrip1.SuspendLayout();        this.SuspendLayout();        //         // menuStrip1        //         this.menuStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {        this.文件ToolStripMenuItem        this.menuStrip1.Location = new System.Drawing.Point(0 0);        this.menuStrip1.Name = ""menuStrip1"";        this.menuStrip1.Size = new System.Drawing.Size(284 25);        this.menuStrip1.TabIndex = 40;        this.menuStrip1.Text = ""menuStrip1"";        //                             //         // 文件ToolStripMenuItem        //         this.文件ToolStripMenuItem.Name = ""文件ToolStripMenuItem"";        this.文件ToolStripMenuItem.Size = new System.Drawing.Size(44 21);        this.文件ToolStripMenuItem.Text = ""文件"";                     this.Controls.Add(this.menuStrip1);        this.menuStrip1.ResumeLayout(false);        this.menuStrip1.PerformLayout();        this.ResumeLayout(false);            }             private System.Windows.Forms.MenuStrip menuStrip1;    private System.Windows.Forms.ToolStripMenuItem 文件ToolStripMenuItem;

解决方案

放在cs中，给你的每个函数增加一个参数，比如
private void addMenuSctrip()
->
private void addMenuSctrip(你的窗体类型 frm)
然后，所有用到
this.Hide();
等地方，都把this换成frm
frm.Hide();

解决方案二：
ToolStripMenuItem menuItem=new ToolStripMenuItem();
ToolStripMenuItem menuSubItem = new ToolStripMenuItem("""");
menuSubItem.Name =""""
menuSubItem.Click += new EventHandler(menuSubItem_Click);
menuItem.DropDownItems.Add(menuSubItem);
