我已经阅读了有关此问题的多篇文章,但它们最终都无法正常工作,或者位于 vb.net 中。
我目前拥有的:
这些报告可通过 URL 进行访问,该 URL 将其呈现为 PDF,并在用户单击按钮时将其保存在下载文件夹中,这些报告具有通用名称,例如 OrderReport、OrderReport(1)... 等。
var orderNum = 1;
"http://Server/ReportServer_Name/Pages/ReportViewer.aspx?%2fOrderReport&rs:Command=Render&OrderID=" + orderNum + "&rs:ClearSession=true&rs:Format=PDF"
我想要实现的目标:
- 如果可能的话,我想使用 C# 获取此报告,然后指定 PDF 文件的名称并将其保存在正确的位置。
例如,我想暂时将此报告保存在临时文件夹中“C:\temp“ 与名字订单ID-1。我正在使用 C#
我已将 ServiceReference 添加到我正在使用的项目中,称为 ReportTestings,因此参考是
using ReportTestings;
和网络参考 URL:
http://服务器/ReportServer_Name/ReportExecution2005.asmx
(出于安全原因删除了真实姓名)
因此,根据上述所有信息,有人可以为我指出正确的方向或给出代码的示例部分,感谢所有阅读这篇文章或提供帮助的人
