如何在IIS上设置rdlc报告的自定义位置?

虽然我可以在调试模式下创建rdlc报告,但我遇到错误“拒绝访问路径'C:\ xxx.xlsx'。”在网上查找解决方法后,我看到许多解决方案建议为IIS用户授予C驱动器权限。但是,仅为呈现报告提供整个驱动器的权限似乎并不明智。那么,如何更改此渲染位置,即C:\ inetpub \ MyApplication?另一方面,我认为报告方面没有需要设置,即ReportViewer.ProcessingMode = ProcessingMode.Local;或更改rdlc属性“构建操作”“复制输出目录”

注意:我不希望报告在客户端的计算机上呈现,因为他们中的一些人无权在C:\下编写任何位置,我认为生成IIS位置的报告要好得多。不是吗?

那么,在这种情况下最好的解决方案是什么?


更新:如何修改此方法,以便只需将其作为excel读取即可?

public static void StreamToProcess(Stream readStream)
{
    var writeStream = new FileStream(String.Format("{0}\\{1}.{2}", Environment.GetFolderPath(Environment.SpecialFolder.InternetCache), "MyFile", "xlsx"), FileMode.Create, FileAccess.Write);
    const int length = 16384;
    var buffer = new Byte[length];
    var bytesRead = readStream.Read(buffer, 0, length);
    while (bytesRead > 0)
    {
        writeStream.Write(buffer, 0, bytesRead);
        bytesRead = readStream.Read(buffer, 0, length);
    }
    readStream.Close();
    writeStream.Close();
    Process.Start(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache) + "\\" + "file" + "." + "xlsx");
}

以下是我们如何从rdlc渲染Excel文件而不将其保存到服务器文件夹。只需调用该操作,它就会下载到用户的浏览器中。

    public FileStreamResult ExcelReport(int type)
    {

        var body = _db.MyObjects.Where(x => x.Type == type);
        ReportDataSource rdsBody = new ReportDataSource("MyReport", body);
        ReportViewer viewer = new ReportViewer 
        { 
            ProcessingMode = ProcessingMode.Local 
        };
        viewer.LocalReport.ReportPath = Server.MapPath(@"~\bin\MyReport.rdlc");
        viewer.LocalReport.DataSources.Clear();
        viewer.LocalReport.DataSources.Add(rdsBody);
        viewer.LocalReport.EnableHyperlinks = true;
        string filename = string.Format("MyReport_{0}.xls", type); 
        byte[] bytes = viewer.LocalReport.Render("Excel");
        var stream = new MemoryStream(bytes);
        return File(stream, "application/ms-excel", filename);
    }
