Spire.XLS 教程:從C#的Excel形狀中提取文本和圖像

一個excel形狀能夠用文字或圖像填充,有時咱們須要讀取形狀中的文字和圖像信息。 在本文中,咱們將介紹如何使用Spire.XLS和C#從Excel中的形狀中提取文本和圖像。html

Step 1: 初始化Workbook類的對象並加載Excel文件。excel

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

Step 2: 獲取第一張工做表。orm

Worksheet sheet = workbook.Worksheets[0];

Step 3: 從第一個形狀中提取文本並保存到txt文件。htm

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

Step 4: 從第二個形狀中提取圖像並保存到本地文件夾。對象

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

namespace Extract_text_and_image_from_Excel_shape
{
    class Program
    {
        static void Main(string[] args)
        {
            //Load the Excel file
            Workbook workbook = new Workbook();
            workbook.LoadFromFile("Input.xlsx");

            //Get the first worksheet
            Worksheet sheet = workbook.Worksheets[0];

            //Extract text from the first shape and save to a txt file
            IPrstGeomShape shape1 = sheet.PrstGeomShapes[0];
            string s = shape1.Text;
            StringBuilder sb = new StringBuilder();
            sb.AppendLine(s);
            File.WriteAllText("ShapeText.txt", sb.ToString()); 

            //Extract image from the second shape and save to a local folder
            IPrstGeomShape shape2 = sheet.PrstGeomShapes[1];
            Image image = shape2.Fill.Picture;
            image.Save(@"Image\ShapeImage.png", ImageFormat.Png);
        }
    }
