[Spire.XLS][] 支持最多添加186种现成形状，如三角形，箭头和标注到Excel工作表。 本文演示如何使用[Spire.XLS][] 和C＃将形状插入Excel工作表，并使用颜色和图片填充形状。

**详细步骤：**

Step 1: 实例化一个Workbook对象并获取第一个工作表。

Workbook workbook = new Workbook();
    Worksheet sheet = workbook.Worksheets[0];

Step 2: 添加三角形，并填充纯色的形状。

//Add a triangle shape
    IPrstGeomShape triangle = sheet.PrstGeomShapes.AddPrstGeomShape(2, 2, 100, 100, PrstGeomShapeType.Triangle);
    
    //Fill the triangle with solid color
    triangle.Fill.ForeColor = Color.Yellow;
    triangle.Fill.FillType = ShapeFillType.SolidColor;

Step 3: 添加心形并用渐变色填充形状。

//Add a heart shape
    IPrstGeomShape heart = sheet.PrstGeomShapes.AddPrstGeomShape(2, 5, 100, 100, PrstGeomShapeType.Heart);
    
    //Fill the heart with gradient color
    heart.Fill.ForeColor = Color.Red;
    heart.Fill.FillType = ShapeFillType.Gradient;

Step 4: 使用默认颜色添加箭头形状。

IPrstGeomShape arrow = sheet.PrstGeomShapes.AddPrstGeomShape(10, 2, 100, 100, PrstGeomShapeType.CurvedRightArrow);

Step 5: 添加云形，并用自定义图片填充形状。

//Add a cloud shape
    IPrstGeomShape cloud = sheet.PrstGeomShapes.AddPrstGeomShape(10, 5, 100, 100, PrstGeomShapeType.Cloud);
    
    //Fill the cloud with picture
    cloud.Fill.CustomPicture(Image.FromFile("Hydrangeas.jpg"), "Hydrangeas.jpg");
    cloud.Fill.FillType = ShapeFillType.Picture;

Step 6: 保存文件。

workbook.SaveToFile("AddShapes.xlsx", ExcelVersion.Version2013);

    {
        class Program
        {
            static void Main(string[] args)
            {
                //Instantiate a workbook object
                Workbook workbook = new Workbook();
                //Get the first worksheet
                Worksheet sheet = workbook.Worksheets[0];
    
                //Add a triangle shape
                IPrstGeomShape triangle = sheet.PrstGeomShapes.AddPrstGeomShape(2, 2, 100, 100, PrstGeomShapeType.Triangle);
                //Fill the triangle with solid color
                triangle.Fill.ForeColor = Color.Yellow;
                triangle.Fill.FillType = ShapeFillType.SolidColor;
    
                //Add a heart shape
                IPrstGeomShape heart = sheet.PrstGeomShapes.AddPrstGeomShape(2, 5, 100, 100, PrstGeomShapeType.Heart);
                //Fill the heart with gradient color
                heart.Fill.ForeColor = Color.Red;
                heart.Fill.FillType = ShapeFillType.Gradient;
    
                //Add an arrow shape with default color
                IPrstGeomShape arrow = sheet.PrstGeomShapes.AddPrstGeomShape(10, 2, 100, 100, PrstGeomShapeType.CurvedRightArrow);
    
                //Add a cloud shape
                IPrstGeomShape cloud = sheet.PrstGeomShapes.AddPrstGeomShape(10, 5, 100, 100, PrstGeomShapeType.Cloud);
                //Fill the cloud with custom picture
                cloud.Fill.CustomPicture(Image.FromFile("Hydrangeas.jpg"), "Hydrangeas.jpg");
                cloud.Fill.FillType = ShapeFillType.Picture;
                
                //Save the file
                workbook.SaveToFile("AddShapes.xlsx", ExcelVersion.Version2013);
            }
        }
    }
