Spire.XLS 教程：从C＃的Excel形状中提取文本和图像

以下是我们用于演示的示例文档的屏幕截图：

详细步骤：

Step 1: 初始化Workbook类的对象并加载Excel文件。

Workbook workbook = new Workbook();workbook.LoadFromFile("Input.xlsx");

Step 2: 获取第一张工作表。

Worksheet sheet = workbook.Worksheets[0];

Step 3: 从第一个形状中提取文本并保存到txt文件。

IPrstGeomShape shape1 = sheet.PrstGeomShapes[0];string s = shape1.Text;StringBuilder sb = new StringBuilder();sb.AppendLine(s);File.WriteAllText("ShapeText.txt", sb.ToString()); 

Step 4: 从第二个形状中提取图像并保存到本地文件夹。

IPrstGeomShape shape2 = sheet.PrstGeomShapes[1];Image image = shape2.Fill.Picture;image.Save(@"ImageShapeImage.png", ImageFormat.Png);
