c# - MenuItem 的颜色变化

Question

我正在编写一个备份工具。在我的工具之上，我有一个包含两个工具条菜单项的菜单条。我根据我的期望稍微改变了颜色。不关注菜单看起来很棒:

当我现在单击菜单项"file"打开上下文菜单时，颜色变为白色，我无法再阅读文本:

谁能告诉我在哪里可以改变这种行为？我使用 Visual Studio 2013 Ultimate，Windows 窗体应用程序，代码在 C# 中。

代码如下:

//
// initializing menuStrip1
//
this.menuStrip1.BackColor = System.Drawing.Color.MediumBlue;
this.menuStrip1.BackgroundImageLayout =
System.Windows.Forms.ImageLayout.Center;
this.menuStrip1.Font = new System.Drawing.Font("Segoe UI Semilight",
15.75F, System.Drawing.FontStyle.Regular,<br/>
System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.menuStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.fileToolStripMenuItem,
this.helpToolStripMenuItem});
this.menuStrip1.Location = new System.Drawing.Point(0, 0);
this.menuStrip1.MinimumSize = new System.Drawing.Size(0, 40);
this.menuStrip1.Name = "menuStrip1";
this.menuStrip1.Size = new System.Drawing.Size(1056, 40);
this.menuStrip1.TabIndex = 77;
this.menuStrip1.Text = "menuStrip1";
//
// initializing fileToolStripMenuItem and adding to menuStrip1
//
this.fileToolStripMenuItem.DropDownItems.AddRange(new
System.Windows.Forms.ToolStripItem[] {
this.saveToolStripMenuItem,
this.saveAsToolStripMenuItem,
this.loadToolStripMenuItem});
this.fileToolStripMenuItem.Font = new System.Drawing.Font("Calibri Light",
15.75F, System.Drawing.FontStyle.Regular,
System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.fileToolStripMenuItem.ForeColor =
System.Drawing.SystemColors.ControlLightLight;
this.fileToolStripMenuItem.Name = "fileToolStripMenuItem";
this.fileToolStripMenuItem.Size = new System.Drawing.Size(54, 36);
this.fileToolStripMenuItem.Text = "File";
this.fileToolStripMenuItem.Click += new System.EventHandler
(this.fileToolStripMenuItem_Click);
//
// initializing saveToolStripMenuItem and adding to fileToolStripMenuItem
//
this.saveToolStripMenuItem.BackColor = System.Drawing.Color.MediumBlue;
this.saveToolStripMenuItem.ForeColor =
System.Drawing.SystemColors.ControlLightLight;
this.saveToolStripMenuItem.Name = "saveToolStripMenuItem";
this.saveToolStripMenuItem.Size = new System.Drawing.Size(166, 30);
this.saveToolStripMenuItem.Text = "Save";
this.saveToolStripMenuItem.Click += new System.EventHandler
(this.saveToolStripMenuItem_Click);
//

您可以创建自己的 ProfessionalColorTable 并覆盖它的属性:

namespace WindowsFormsApplication1
{
     public partial class Form1 : Form
     {
         public Form1()
         {
             InitializeComponent();
             menuStrip1.Renderer = new ToolStripProfessionalRenderer(new MyColorTable());
         }
     }

     public class MyColorTable : ProfessionalColorTable
     {
         public override Color ToolStripDropDownBackground
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color ImageMarginGradientBegin
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color ImageMarginGradientMiddle
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color ImageMarginGradientEnd
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color MenuBorder
         {
             get
             {
                 return Color.Black;
             }
         }

         public override Color MenuItemBorder
         {
             get
             {
                 return Color.Black;
             }
         }

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

         public override Color MenuStripGradientBegin
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color MenuStripGradientEnd
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color MenuItemSelectedGradientBegin
         {
             get
             {
                 return Color.Navy;
             }
         }

         public override Color MenuItemSelectedGradientEnd
         {
             get
             {
                 return Color.Navy;
             }
         }

         public override Color MenuItemPressedGradientBegin
         {
             get
             {
                 return Color.Blue;
             }
         }

         public override Color MenuItemPressedGradientEnd
         {
             get
             {
                 return Color.Blue;
             }
         }
     }
}

这是上面代码的结果:
