第一步：生成PDF文件
protected void LinkButtonPrint_Click(object sender, EventArgs e)
{
try
{
string contractContentUrl = GetWebVirtualPath(HttpContext.Current) + "PrintPDF?kind=" + this.Kind.Replace("+", "%2B") + "&NO=" + this.No.ToString().Replace("+", "%2B");
string pdfFilePath = FormHelp.GetFormConfig(this.FormKind, "PDF_FILE");
string pdfFileName = pdfFilePath + Guid.NewGuid().ToString() + ".pdf";
string path = Server.MapPath(Request.ApplicationPath);
string pdfConverter = path + @"\bin\wkhtmltopdf.exe";
if (!System.IO.File.Exists(pdfConverter))
return;
Process printProcess = new Process();
printProcess.StartInfo.FileName = pdfConverter;
string printArguments = "\"{0}\" \"{1}\"";
contractContentUrl = contractContentUrl.Replace("https:", "http:");
printArguments = string.Format(printArguments, contractContentUrl, pdfFileName);
printProcess.StartInfo.Arguments = printArguments;
printProcess.StartInfo.UseShellExecute = false;
printProcess.StartInfo.RedirectStandardInput = true;
printProcess.StartInfo.RedirectStandardOutput = true;
printProcess.StartInfo.RedirectStandardError = true;
printProcess.StartInfo.CreateNoWindow = false;
printProcess.Start();
string output = printProcess.StandardOutput.ReadToEnd();
if (!string.IsNullOrEmpty(output))
{
LogHelp.WriteInfoLog(this.FormKind, output);
}
printProcess.WaitForExit();
System.Threading.Thread.Sleep(500);
DownLoadPDF(pdfFileName);
}
catch (Exception ex)
{
throw ex;
}
}
第二步：下载PDF文件
/// <summary>
/// download pdf
/// </summary>
/// <param name="fileName"></param>
private void DownLoadPDF(string fileName)
{
//string PDFFilePath = Server.MapPath("../PDFFile/") + Request.QueryString["FileName"].Trim() + ".PDF";
FileStream fs = new FileStream(fileName, FileMode.Open);
BinaryReader br = new BinaryReader(fs);
byte[] BynFile = new byte[br.BaseStream.Length];
br.BaseStream.Seek(0, SeekOrigin.Begin);
br.Read(BynFile, 0, (int)br.BaseStream.Length);
fs.Close();
Response.Buffer = true;
Response.Clear();
Response.Charset = "UTF-8";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.AddHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(ContractName + ".pdf"));
//Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/pdf";
Response.BinaryWrite(BynFile);
System.IO.FileInfo file = new System.IO.FileInfo(fileName);
if (File.Exists(fileName))
{
File.Delete(fileName);
}
Response.Flush();
Response.End();
}
通过下面的组件进行HTML导出PDF格式文件：
