C# 在Asp.net MVC中以pdf格式查看RDLC报告

在过去的两天里，我面临着这个问题。我试图在没有reportviewer的情况下以pdf格式查看rdlc报告。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;
        }           
    }

导出到User->AppData->Temp的pdf文件

            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

这段代码在我的本地机器上运行良好。但是，当我将其发布到IIS服务器并运行时，尝试将导出的pdf文件获取到客户端PC不成功。我怎样才能解决这个问题。有人能帮我吗

提前感谢…

最后，我找到了一个在asp.net MVC中以pdf格式查看RDLC报告的解决方案。解决办法如下

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;
    }           
}

在您添加Export（）方法的返回文件（filePath，“application/pdf”）中出现错误？直接在控制器中还是单独的类中？是否在项目参考中添加了正确版本的Microsoft.ReportViewer.WebForms.dll@ElbertJohnFelipeI在您添加Export（）方法的返回文件（filePath，“application/pdf”）中获取错误？直接在控制器中还是单独的类中？是否在项目参考中添加了正确版本的Microsoft.ReportViewer.WebForms.dll@埃尔伯特约翰费利佩
