## Add(double, CellsColor, int) {#add}

Add a gradient stop.

```csharp
public void Add(double position, CellsColor color, int alpha)
```

| Parameter | Type | Description |
| --- | --- | --- |
| position | Double | The position of the stop,in unit of percentage. |
| color | CellsColor | The color of the stop. |
| alpha | Int32 | The alpha of the color. |

### Examples

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

    public class GradientStopCollectionMethodAddWithDoubleCellsColorInt32Demo
    {
        public static void Run()
        {
            Workbook workbook = new Workbook();
            Worksheet worksheet = workbook.Worksheets[0];

            var shape = worksheet.Shapes.AddShape(MsoDrawingType.Rectangle, 2, 0, 2, 0, 300, 100);
            shape.Fill.FillType = FillType.Gradient;
            
            GradientStopCollection gradientStops = shape.Fill.GradientFill.GradientStops;
            gradientStops.Clear();

            try
            {
                // Create CellsColor using factory method
                CellsColor gradientColor = workbook.CreateCellsColor();
                gradientColor.Color = Color.DarkOrange;

                gradientStops.Add(0.3, gradientColor, 192);

                Console.WriteLine("Gradient stop added successfully");
                workbook.Save("GradientStopAddDemo.xlsx");
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error adding gradient stop: {ex.Message}");
            }
        }
    }
}
