问题描述

我想使用以下代码获得pdf格式的rdlc报告。

i want to get only pdf format of rdlc report using following code.

protected void ReportViewer2_Load(object sender, EventArgs e)
{
    string exportOption = "Word";
    string exportOption1 = "Excel";
    RenderingExtension extension = ReportViewer2.LocalReport.ListRenderingExtensions().ToList().Find(x => x.Name.Equals(exportOption, StringComparison.CurrentCultureIgnoreCase));
    if (extension != null)
    {
        System.Reflection.FieldInfo fieldInfo = extension.GetType().GetField("m_isVisible", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
        fieldInfo.SetValue(extension, false);
    }
    RenderingExtension extension1 = ReportViewer2.LocalReport.ListRenderingExtensions().ToList().Find(x => x.Name.Equals(exportOption1, StringComparison.CurrentCultureIgnoreCase));
    if (extension1 != null)
    {
        System.Reflection.FieldInfo fieldInfo1 = extension1.GetType().GetField("m_isVisible", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);

推荐答案

现在我将展示如何在运行时将RDLC报告保存为PDF格式。



我正在创建一个名为SAVEPDFData的方法，其中包含两个参数：



路径（位置）为字符串键入我们要保存该PDF文件的位置。



示例：C：\ MyFile \



另一个是ReportViewer，它是ReportViewer类的实例



我们将执行将报告转换为PDF的操作;但不仅仅是PDF，我们可以将文件保存为其他格式，例如Word或Excel。

Now I show how to save a RDLC report as a PDF at run time.

I am creating a method for that named "SAVEPDFData" with the two arguments:

Path (Location) as string type where we want to save that PDF file.

Example: C:\MyFile\

Another is ReportViewer that is the instance of the ReportViewer Class

On which we will perform the action to convert the report to a PDF; but not just PDF, we can save the file in another format, such as Word or Excel.

public void SavePDFData(ReportViewer viewer, string savePath)

{
     byte[] Bytes = viewer.LocalReport.Render(format:"PDF",deviceInfo:"");

     using (FileStream stream = new FileStream(savePath, FileMode.Create))
     {
              stream.Write(Bytes, 0, Bytes.Length);
    }
 }
