如何遍历toolStrip1控件上的所有项目

Question

如何遍历toolStrip1控件上的所有项目,并将设置其Enabled = false;但是遇到ToolStripSeparator项就会报错,该如何处理?

Answer 1

既然你知道是ToolStripSeparator，那就判断一下，对其做特殊处理

Answer 2

现在的问题是:toolStrip1控件嵌套了很多项,各种都有,判断ToolStripSeparator后遍历又成问题了.弄了一晚上也没有搞定,郁闷.

Answer 3

xxx.Enabled = false;改成if(xxx is ToolStripSeparator)
    continue;
xxx.Enabled = false;

public static class myToolStrip
        {
            public static void SetEnabled(ToolStrip myToolStrip)
            {
                for (int i = 0; i < myToolStrip.Items.Count; i++)
                {
                    //
                    //先控制第一级控件,并且ToolStripLabel, ToolStripButton, ToolStripTextBox ,ToolStripComboBox,ToolStripProgressBar 无级联菜单
                    //
                    myToolStrip.Items[i].Enabled = false;
                    //
                    // ToolStripMenuItem, ToolStripSplitButton ,ToolStripDropDownButton 有级联菜单
                    //
                    TraverseItems(myToolStrip.Items[i]);
                }               
            }            private static void TraverseItems(ToolStripItem myItems)
            {
                if (!(myItems is ToolStripSeparator))
                {
                    myItems.Enabled = false;
                    if (myItems is ToolStripMenuItem)
                    {
                        ToolStripMenuItem myMenuItem = (ToolStripMenuItem)myItems;
                        if (myMenuItem.DropDownItems.Count > 0)
                        {
                            for (int i = 0; i < myMenuItem.DropDownItems.Count; i++)
                            {
                                myItems.Enabled = false;
                                TraverseItems(myMenuItem.DropDownItems[i]);
                            }
                        }
                    }
                    //
                    if (myItems is ToolStripSplitButton)
                    {
                        ToolStripSplitButton mySplitButton = (ToolStripSplitButton)myItems;
                        if (mySplitButton.DropDownItems.Count > 0)
                        {
                            for (int i = 0; i < mySplitButton.DropDownItems.Count; i++)
                            {
                                myItems.Enabled = false;
                                TraverseItems(mySplitButton.DropDownItems[i]);
                            }
                        }
                    }
                    //
                    if (myItems is ToolStripDropDownButton)
                    {
                        ToolStripDropDownButton myDropDownButton = (ToolStripDropDownButton)myItems;
                        if (myDropDownButton.DropDownItems.Count > 0)
                        {
                            for (int i = 0; i < myDropDownButton.DropDownItems.Count; i++)
                            {
                                myItems.Enabled = false;
                                TraverseItems(myDropDownButton.DropDownItems[i]);
                            }
                        }
                    }
                }                           }
}我是这样写的,可是还是有问题,请大家帮我看一看.

这样改感觉可以了.想简化一下代码.
