How to get/read picture from Excel file (xlsx) using EPPlus

问题

Let's assume I have a worksheet named sheet1 which contain a picture named pic_001 How can I get this picture as System.Drawing.Image object.

回答1:

OK I found out how to:

public static Image GetImage(string sheetname, ExcelPackage excelFile)
    {
      var sheet = excelFile.Workbook.Worksheets[sheetname];
      var pic = sheet.Drawings["pic_001"] as ExcelPicture;
      return pic.Image;
    }

all xlsx files are really zip files. you can copy/rename the .xlsx extension to .zip and navigate the folder hierarchy yourself. navigate to xl/media to see your images. there are certainly more efficient ways of doing this, but this is a quick and dirty solution that will get the job done.
