我想在Excel中添加图片。我使用图书馆EPPLus。有必要获得BASE64格式的图像并插入Excel中的单元格
我的代码:
using (System.Drawing.Image img = Base64ToImage(base64String))
{
ExcelPicture excelImage = null;
if (img != null)
{
ERROR HERE excelImage = worksheet.Drawings.AddPicture("Title", img);
excelImage.From.Column = 1;
excelImage.From.Row = 1;
excelImage.SetSize(100, 100);
}
}
public Image Base64ToImage(string base64String)
{
// Convert base 64 string to byte[]
byte[] imageBytes = Convert.FromBase64String(base64String);
// Convert byte[] to Image
using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
{
Image image = Image.FromStream(ms, true);
return image;
}
}
