iText夏普在合并Excel文件

我使用iText Sharp将两个PDF文件合并成一个PDF文件。 但是，是否有可能使用iText Sharp将excel文件合并为PDF文件？ 我尝试了很多次，但它不适合我。这是我的PDF合并代码：

protected void btnMerge_Click(object sender, EventArgs e) { if (file1.HasFile && file2.HasFile) { PdfReader pdfReader1 = new PdfReader(file1.PostedFile.InputStream); PdfReader pdfReader2 = new PdfReader(file2.PostedFile.InputStream); List<PdfReader> readerList = new List<PdfReader>(); readerList.Add(pdfReader1); readerList.Add(pdfReader2); //Define a new output document and its size, type Document document = new Document(PageSize.A4, 0, 0, 0, 0); //Get instance response output stream to write output file. PdfWriter writer = PdfWriter.GetInstance(document, Response.OutputStream); document.Open(); foreach (PdfReader reader in readerList) { for (int i = 1; i <= reader.NumberOfPages; i++) { PdfImportedPage page = writer.GetImportedPage(reader, i); document.Add(iTextSharp.text.Image.GetInstance(page)); } } document.Close(); Response.AppendHeader("content-disposition", "inline; filename=OutPut.pdf"); Response.ContentType = "application/pdf"; } } private void MergePDFs(string outPutFilePath, params string[] filesPath) { List<PdfReader> readerList = new List<PdfReader>(); foreach (string filePath in filesPath) { PdfReader pdfReader = new PdfReader(filePath); readerList.Add(pdfReader); } //Define a new output document and its size, type Document document = new Document(PageSize.A4, 0, 0, 0, 0); //Create blank output pdf file and get the stream to write on it. PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(outPutFilePath, FileMode.Create)); document.Open(); foreach (PdfReader reader in readerList) { for (int i = 1; i <= reader.NumberOfPages; i++) { PdfImportedPage page = writer.GetImportedPage(reader, i); document.Add(iTextSharp.text.Image.GetInstance(page)); } } document.Close(); } } 

}
