在Asp.net MVC中以pdf格式查看RDLC报告 [英] View RDLC Report as pdf in Asp.net MVC

问题描述

最近两天我遇到了问题.我正在尝试在没有reportviewer的情况下将rdlc报告查看为pdf.我使用以下代码将rdlc导出为pdf ...

public string Export(LocalReport rpt, string filePath)
    {
        string ack = "";
        try
        {                
            Warning[] warnings;
            string[] streamids;
            string mimeType;
            string encoding;
            string extension;

            byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
            using (FileStream stream = File.OpenWrite(filePath))
            {
                stream.Write(bytes, 0, bytes.Length);
            }
            return ack;
        }
        catch(Exception ex)
        {
            ack = ex.InnerException.Message;
            return ack;
        }           
    }

将pdf文件导出到User-> AppData-> Temp

            string filePath = System.IO.Path.GetTempFileName();
            string ack = Export(rpt, Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc"));                
            System.Diagnostics.Process.Start(filePath);

我想将此pdf文件呈现到客户端PC.

此代码在我的本地计算机上正常工作.但是，当我将其发布到IIS服务器并运行以尝试将导出的pdf文件获取到客户端PC时，操作并不成功.我该如何解决这个问题.谁能帮我.

预先感谢...

最后，我在asp.net MVC中找到了一种以pdf格式查看RDLC报告的解决方案.解决方案如下...

public FileResult ViewReport()
    {            
        string RptPath = Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc");                  
        Microsoft.Reporting.WebForms.LocalReport rpt = new Microsoft.Reporting.WebForms.LocalReport(); 

        /* Bind Here Report Data Set */

        rpt.ReportPath = RptPath;
        string filePath = System.IO.Path.GetTempFileName();               
        Export(rpt, filePath);
        //CLOSE REPORT OBJECT           
        rpt.Dispose();
        return File(filePath, "application/pdf");
    } 

我使用以下方法从RDLC生成pdf....

public string Export(LocalReport rpt, string filePath)
{
    string ack = "";
    try
    {                
        Warning[] warnings;
        string[] streamids;
        string mimeType;
        string encoding;
        string extension;

        byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
        using (FileStream stream = File.OpenWrite(filePath))
        {
            stream.Write(bytes, 0, bytes.Length);
        }
        return ack;
    }
    catch(Exception ex)
    {
        ack = ex.InnerException.Message;
        return ack;
    }           
}

I am facing problem in last two days. I am trying to view rdlc report as pdf without reportviewer. I export rdlc to pdf using the following code...

public string Export(LocalReport rpt, string filePath)
    {
        string ack = "";
        try
        {                
            Warning[] warnings;
            string[] streamids;
            string mimeType;
            string encoding;
            string extension;

            byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
            using (FileStream stream = File.OpenWrite(filePath))
            {
                stream.Write(bytes, 0, bytes.Length);
            }
            return ack;
        }
        catch(Exception ex)
        {
            ack = ex.InnerException.Message;
            return ack;
        }           
    }

The pdf file exported to User->AppData->Temp

            string filePath = System.IO.Path.GetTempFileName();
            string ack = Export(rpt, Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc"));                
            System.Diagnostics.Process.Start(filePath);

Thanks In Advance...

解决方案

Finally, i found one solution about view RDLC report as pdf in asp.net MVC. The solution is following....

public FileResult ViewReport()
    {            
        string RptPath = Server.MapPath("~/Reports/Mymun_Lab/ComparisonStudy.rdlc");                  
        Microsoft.Reporting.WebForms.LocalReport rpt = new Microsoft.Reporting.WebForms.LocalReport(); 

        /* Bind Here Report Data Set */

        rpt.ReportPath = RptPath;
        string filePath = System.IO.Path.GetTempFileName();               
        Export(rpt, filePath);
        //CLOSE REPORT OBJECT           
        rpt.Dispose();
        return File(filePath, "application/pdf");
    } 

I use the following method for generate pdf from RDLC....

public string Export(LocalReport rpt, string filePath)
{
    string ack = "";
    try
    {                
        Warning[] warnings;
        string[] streamids;
        string mimeType;
        string encoding;
        string extension;

        byte[] bytes = rpt.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
        using (FileStream stream = File.OpenWrite(filePath))
        {
            stream.Write(bytes, 0, bytes.Length);
        }
        return ack;
    }
    catch(Exception ex)
    {
        ack = ex.InnerException.Message;
        return ack;
    }           
}
