C#

// Create a rectangle.
Shape rectangle = document.Shapes.InsertShape(document.Range.Start, ShapeGeometryPreset.Rectangle, new RectangleF(300, 200, 500, 300));
rectangle.Fill.SetNoFill();
// Format the rectangle's outline.
ShapeLine border = rectangle.Line;
// Apply a gradient of two colors to the outline.
border.Fill.SetGradientFill(GradientType.Linear, Color.FromArgb(0x4D, 0x64, 0x8D), Color.FromArgb(0xFF, 0x8B, 0x94));
// Set the line width.
border.Thickness = 6;

VB.NET

' Create a rectangle.
Dim rectangle As Shape = document.Shapes.InsertShape(document.Range.Start, ShapeGeometryPreset.Rectangle, New RectangleF(300, 200, 500, 300))
rectangle.Fill.SetNoFill()
' Format the rectangle's outline.
Dim border As ShapeLine = rectangle.Line
' Apply a gradient of two colors to the outline.
border.Fill.SetGradientFill(GradientType.Linear, Color.FromArgb(&H4D, &H64, &H8D), Color.FromArgb(&HFF, &H8B, &H94))
' Set the line width.
border.Thickness = 6
