移除 ToolStripMenuItem 左边框

Question

我有我的ToolStripMenuItem，当我运行应用程序时，它看起来像这样：

如您所见，ToolStripMenuItem左侧有一点空白。

我怎样才能删除它？我试图编辑每个属性，但它仍然存在......

谢谢大家！

要更改菜单项的外观，您应该使用ToolStripProfessionalRenderer自定义ProfessionalColorTable.

要更改该颜色，您应该覆盖ImageMarginGradientBegin自定义颜色表的属性并返回您想要的颜色。

例如你可以有：

public class CustomColorTable : ProfessionalColorTable
{
    public override Color ImageMarginGradientBegin
    {
        get { return Color.Red; }
    }
    public override Color ImageMarginGradientMiddle
    {
        get { return Color.Green; }
    }
    public override Color ImageMarginGradientEnd
    {
        get { return Color.Blue; }
    }
    public override Color ToolStripDropDownBackground
    {
        get { return Color.Yellow; }
    }

    public override Color MenuItemSelected
    {
        get { return Color.Pink; }
    }

    //You should also override other properties if you need.
    //This is just a sample code to show you the solution
}

然后在您的表单中加载：

private void Form_Load(object sender, EventArgs e)
{
    ToolStripManager.Renderer = new ToolStripProfessionalRenderer(new CustomColorTable());
}
