## GradientFill.SetGradient method

Set the gradient fill type and direction.

```csharp
public void SetGradient(GradientFillType type, double angle, GradientDirectionType direction)
```

| Parameter | Type | Description |
| --- | --- | --- |
| type | GradientFillType | Gradient fill type. |
| angle | Double | The angle. Only applies for GradientFillType.Linear. |
| direction | GradientDirectionType | The direction type. Only applies for GradientFillType.Radial and GradientFillType.Rectangle. |

### Examples

```csharp
namespace AsposeCellsExamples
{
    using Aspose.Cells;
    using Aspose.Cells.Drawing;
    using System;

    public class GradientFillMethodSetGradientWithGradientFillTypeDoubleGradientDemo
    {
        public static void Run()
        {
            // Create a new workbook
            Workbook workbook = new Workbook();
            Worksheet worksheet = workbook.Worksheets[0];
            
            // Add a shape to apply gradient fill
            Shape shape = worksheet.Shapes.AddRectangle(0, 0, 100, 100, 200, 100);

            try
            {
                // Get the shape's fill gradient
                GradientFill gradientFill = shape.Fill.GradientFill; // Fixed property name from Gradient to GradientFill
                if (gradientFill == null)
                {
                    Console.WriteLine("Cannot set gradient: The shape's fill is not a GradientFill.");
                    return;
                }

                // Call SetGradient with specific parameters: Linear fill, 90 degrees, FromCenter direction
                gradientFill.SetGradient(GradientFillType.Linear, 90.0, GradientDirectionType.FromCenter);
                
                Console.WriteLine("SetGradient method executed successfully with parameters (GradientFillType.Linear, 90.0, GradientDirectionType.FromCenter)");
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error executing SetGradient method: {ex.Message}");
            }
            
            // Save the workbook to demonstrate the effect
            workbook.Save("GradientFillSetGradientDemo.xlsx");
        }
    }
}
```
