我们如何在C#中使用iTextSharp将数据表导出为PDF?
public void ExportToPdf(DataTable dt)
{
Document document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("c://sample.pdf", FileMode.Create));
document.Open();
PdfPTable table = new PdfPTable(dt.Columns.Count);
PdfPRow row = null;
float[] widths = new float[] { 2f, 2f, 2f, 2f };
table.SetWidths(widths);
table.WidthPercentage = 100;
PdfPCell cell = new PdfPCell(new Phrase("Products"));
cell.Colspan = dt.Columns.Count;
}
最佳答案
这是示例代码。请检查一下。
public void ExportToPdf(DataTable dt)
{
Document document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("c://sample.pdf", FileMode.Create));
document.Open();
iTextSharp.text.Font font5 = iTextSharp.text.FontFactory.GetFont(FontFactory.HELVETICA, 5);
PdfPTable table = new PdfPTable(dt.Columns.Count);
PdfPRow row = null;
float[] widths = new float[] { 4f, 4f, 4f, 4f };
table.SetWidths(widths);
table.WidthPercentage = 100;
int iCol = 0;
string colname = "";
PdfPCell cell = new PdfPCell(new Phrase("Products"));
cell.Colspan = dt.Columns.Count;
foreach (DataColumn c in dt.Columns)
{
table.AddCell(new Phrase(c.ColumnName, font5));
}
foreach (DataRow r in dt.Rows)
{
if (dt.Rows.Count > 0)
{
table.AddCell(new Phrase(r[0].ToString(), font5));
table.AddCell(new Phrase(r[1].ToString(), font5));
table.AddCell(new Phrase(r[2].ToString(), font5));
table.AddCell(new Phrase(r[3].ToString(), font5));
}
} document.Add(table);
document.Close();
}
