嗨Debra，

Hi Debra,

你可以参考这个帖子：

http://stackoverflow.com/questions/7822514/multi-color-linear-gradient-in-winforms

这里有一个小例子给你启发通过这篇文章



http://www.bobpowell.net/linear.htm（多色混合）

here is a little example for you inspired by this article

http://www.bobpowell.net/linear.htm (Multiple colour blends)

void MainFormPaint(object sender, PaintEventArgs e)
{
  LinearGradientBrush br = new LinearGradientBrush(this.ClientRectangle, Color.Black, Color.Black, 0 , false);
  ColorBlend cb = new ColorBlend();
  cb.Positions = new[] {0, 1/6f, 2/6f, 3/6f, 4/6f, 5/6f, 1};
  cb.Colors = new[] {Color.Red, Color.Orange, Color.Yellow, Color.Green, Color.Blue, Color.Indigo, Color.Violet};
  br.InterpolationColors= cb;
  // rotate
  br.RotateTransform(45);
  // paint
  e.Graphics.FillRectangle(br, this.ClientRectangle);
}

这里是结果

或者您可以为winform插入背景图片。 http://msdn.microsoft.com/en-us/library/system.windows.forms.control.backgroundimage（v = VS.100）的.aspx

Or you may insert background image for winform.http://msdn.microsoft.com/en-us/library/system.windows.forms.control.backgroundimage(v=vs.100).aspx

// Add a button to a form and set some of its common properties.
private void AddMyButton()
{
   // Create a button and add it to the form.
   Button button1 = new Button();

   // Anchor the button to the bottom right corner of the form
   button1.Anchor = (AnchorStyles.Bottom | AnchorStyles.Right);

   // Assign a background image.
   button1.BackgroundImage = imageList1.Images[0];

   // Specify the layout style of the background image. Tile is the default.
   button1.BackgroundImageLayout = ImageLayout.Center;

   // Make the button the same size as the image.
   button1.Size = button1.BackgroundImage.Size;

   // Set the button's TabIndex and TabStop properties.
   button1.TabIndex = 1;
   button1.TabStop = true;

   // Add a delegate to handle the Click event.
   button1.Click += new System.EventHandler(this.button1_Click);

   // Add the button to the form.
   this.Controls.Add(button1);
}
