2、PDF转换方法
/// <summary>
/// datatable转PDF方法
/// </summary>
/// <param name="Data">dataTable数据</param>
/// <param name="PDFFile">PDF文件保存的路径</param>
/// <param name="FontSize">字体大小</param>
/// <returns></returns>
public bool ConvertDataTableToPDF(DataTable Data, string PDFFile, float FontSize)
{
//默认页面大小
Document document = new Document();
document.SetPageSize(PageSize.A2);
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(PDFFile, FileMode.Create));
document.Open();
//设置字体
//BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
//Font font = new Font(bf, FontSize);
//设置字体,支持中文
BaseFont bfChinese = BaseFont.CreateFont("C:\\WINDOWS\\Fonts\\simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
iTextSharp.text.Font fontChinese = new iTextSharp.text.Font(bfChinese, 12, iTextSharp.text.Font.NORMAL, new BaseColor(0, 0, 0));
PdfPTable table = new PdfPTable(Data.Columns.Count);
table.WidthPercentage = 100; // percentage
table.DefaultCell.Padding = 1;
table.DefaultCell.BorderWidth = 1;
table.DefaultCell.HorizontalAlignment = Element.ALIGN_LEFT;
//将datatable表头转换成PDFTable的表头
foreach (DataColumn dc in Data.Columns)
{
table.AddCell(new Phrase(dc.ColumnName.ToString(), fontChinese));
}
//插入数据
for (int i = 0; i < Data.Rows.Count; i++)
{
for (int j = 0; j < Data.Columns.Count; j++)
{
table.AddCell(new Phrase(Data.Rows[i][j].ToString(), fontChinese));
}
}
document.Add(table);
document.Close();
writer.Close();
return true;
}
3、调用代码
private void btnCreatePDF_Click(object sender, EventArgs e)
{
//获取datatable数据
DataTable tab = GetDataTableList();
//获取保存路径
string savePath = "D://PDF//";
string saveName = "PDF文件.pdf";
CreateFileDirectory(savePath);
//文件路径：保存路径+保存名称
string path = savePath + saveName;
//调用转化PDF的方法
ConvertDataTableToPDF(tab,path,12);
}
4、调用界面
