Question

RDLC报表（Microsoft reportViewer）部署到服务器后未呈现当从机器本身访问时，我的rdlc报告可以正确地渲染并在开发机器中（在部署后）工作，而在部署（当从机器本身内部进行访问）时，它也可以在生产服务器中工作。但是，当我尝试从客户端计算机访问报告时，它不能使Web应用程序的其他组件正常工作。

我得到的错误是：

google chrome：无法加载pdf文档

Internet Explorer：文件已损坏，无法修复

如何解决此错误？

我的控制器代码是：

        Function GenerateReportS(value As String, lcvalue As String) As ActionResult
        Dim assetlist As List(Of usp_standardreportquery_Result)
        If value IsNot Nothing Or lcvalue IsNot Nothing Then
            assetlist = db.usp_standardreportquery.Where(Function(r) If(value IsNot Nothing, r.AssignLocation = value, True) And
                                                             If(lcvalue IsNot Nothing, r.LocationCategory = lcvalue, True)).ToList
        Else
            assetlist = db.usp_standardreportquery.ToList
        End If

        Dim warnings As Warning()
        Dim mimeType As String
        Dim streamids As String()
        Dim encoding As String
        Dim filenameExtension As String

        Dim viewer = New ReportViewer()
        viewer.LocalReport.ReportPath = "Views\Reports\StandardReport.rdlc"

        Dim dataset As Microsoft.Reporting.WebForms.ReportDataSource = New Microsoft.Reporting.WebForms.ReportDataSource("standardreportds", assetlist)

        viewer.LocalReport.DataSources.Add(dataset)
        Dim params(2) As ReportParameter
        params(0) = New ReportParameter("SearchBy", "Location", False)
        params(1) = New ReportParameter("value", value, False)
        params(2) = New ReportParameter("Category", lcvalue, False)

        viewer.LocalReport.SetParameters(params)

        dataset.Value = assetlist
        viewer.LocalReport.Refresh()

        Dim bytes = viewer.LocalReport.Render("PDF", Nothing, mimeType, encoding, filenameExtension, streamids,
warnings)

        Return New FileContentResult(bytes, mimeType)

        'Return File(bytes, mimeType, "_PackingSlip.pdf")
    End Function

我该如何解决此错误？

因为错误“无法加载pdf文件”很难解决，所以浪费了很多时间并在网上搜索后，我以同伴的身份解决了这个问题。

更正

中的初始化

Dim warnings As Warning()
Dim streamids As String()
Dim mimeType As String = "application/pdf"
Dim encoding As String = String.Empty
Dim filenameExtension As String = String.Empty

最后在Dim bytes =

之后插入以下代码

Response.Buffer = True
Response.Clear()
Response.ContentType = mimeType
Response.BinaryWrite(bytes)
Response.Flush()

部署到服务器后从客户端计算机访问时，RDLC报告（Microsoft reportViewer）无法呈现
