Shape shape = new Rectangle();
shape.Width = 25;
shape.Height = 200;
var linearGradientBrush = new LinearGradientBrush();
linearGradientBrush.StartPoint = new Point(0.5, 0);
linearGradientBrush.EndPoint = new Point(0.5, 1);
var random = new Random();
for (int i = 0; i < 100; i++)
{
    var color = new Color();
    color.A = byte.MaxValue;
    color.R = (byte)random.Next(0, byte.MaxValue + 1);
    color.G = (byte)random.Next(0, byte.MaxValue + 1);
    color.B = (byte)random.Next(0, byte.MaxValue + 1);
    var gradientStop = new GradientStop();
    gradientStop.Color = color;
    gradientStop.Offset = 0.01 * i;
    linearGradientBrush.GradientStops.Add(gradientStop);
}
shape.Fill = linearGradientBrush;
this.MainGrid.Children.Add(shape);

这样么？
