用C#访问SSRS自动导出SSRS报表

一、              新建一个winform应用程序WindowsFormsApplication1

二、              添加web引用 。

报表服务：http://dbpdhkcax05:80/webservice/ReportService2005.asmx

报表执行服务：http://dbpdhkcax05:80/webservice/ReportExecution2005.asmx

右击“引用”-> 添加服务引用->输入URL地址点“前往”载入服务后点“高级”-服务引用设置->点“添加web引用”->在此画面将2个服务都加入项目。

三、              web服务引用如图示。（web服务引用的节点一开始没有，在添加web服务引用后自动产生）.

四、              建一form用于输入参数。

五、              点OK产生报表（VS2008)

1.插入命名空间引用

using WindowsFormsApplication1.dbpdhkcax05_rs;
using WindowsFormsApplication1.dbpdhkcax05_rsexec;

2.Click OK 代码

            dbpdhkcax05_rs.ReportingService2005 rs2005 = new ReportingService2005();
            dbpdhkcax05_rsexec.ReportExecutionService rsExec = new ReportExecutionService();

            rs2005.Credentials = System.Net.CredentialCache.DefaultCredentials;

            rsExec.SetExecutionParameters(parameters, "en-us");
            Byte[] results;
            string encoding = String.Empty;

            results = rsExec.Render(format, devInfo, out extension, out mimeType, out encoding, out warning, out streamIDs);
            using (FileStream stream = File.OpenWrite(fileName))
            {
                stream.Write(results, 0, results.Length);

            }
