Create IMageButton and add to toolstrip:

ImageButton imageButton1 = new ImageButton(); toolstrip.Items.AddRange(new System.Windows.Forms.ToolStripItem[] { imageButton1});

最满意答案

您不能简单地将控件添加到ToolStrip ， ContextStrip或StatusStrip 。

它需要从ToolStripItem继承。

虽然有一个简单的方法：

ImageButton imageButton1 = new ImageButton(); var host = new ToolStripControlHost(imageButton1); toolstrip.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {host});

或者更好，扩展ToolStripControlHost类，如：

public class ImageButtonItem: ToolStripControlHost { private ImageButton imgButton; public ImageButtonItem() : base(new ImageButton()) { this.imgButton = this.Control as ImageButton; } // Add properties, events etc. you want to expose... }

按照此MSDN howto进一步了解相关信息。

PS

您还可以在设计器中显示自定义ImageButtonItem ，将ToolStripItemDesignerAvailability属性添加到ImageButtonItem类中。

You can't simply add a control to a ToolStrip, ContextStrip or StatusStrip.

It needs to inherit from ToolStripItem.

There's a simple way to do it though:

ImageButton imageButton1 = new ImageButton(); var host = new ToolStripControlHost(imageButton1); toolstrip.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {host});

or better, extend ToolStripControlHost class like:

public class ImageButtonItem: ToolStripControlHost { private ImageButton imgButton; public ImageButtonItem() : base(new ImageButton()) { this.imgButton = this.Control as ImageButton; } // Add properties, events etc. you want to expose... }

follow this MSDN howto to further infos.

P.S.

You can also show your custom ImageButtonItem in the designer adding the ToolStripItemDesignerAvailability attribute onto your ImageButtonItem class.
