c# – 打开从调用Reporting Services Web服务ReportExecution2005创建的Xlsx文件时出错

我无法打开呈现为xlsx文件的SSRS报告,该报告是通过从SSIS脚本任务调用Reporting Services Web服务ReportExecution2005.asmx？wsdl生成的.
但我可以打开由同一方法生成的xls文件.

有人可以告诉我,我需要做些什么才能呈现可用的xlsx文件？

我正在尝试使用脚本任务从SSIS运行Reporting Services报告.
我需要将报告呈现为Excel xlsx文件.
如果我使用.xls扩展名,我的代码可以工作,我的意思是它确实会产生一个可以在Excel中打开的xls文件.但是如果我将文件扩展名更改为xlsx,我会得到一个无法打开的文件,并产生以下错误.
“Excel无法打开文件,因为文件格式或文件扩展名无效.验证文件……… ..“

在我的代码我正在使用

MimeType = “application/vnd.ms-excel” for the xls file

和

MimeType =“application / vnd.openxmlformats-officedocument.spreadsheetml.sheet
”

对于xlsx文件

我用来运行报告的Web服务是ReportExecution2005.asmx？wsdl
(我假设它是正确的？)

我在SSIS脚本任务中的代码如下,

        var rsClient = new RSExec.ReportExecutionServiceSoapClient();

        rsClient.ClientCredentials.Windows.ClientCredential = new System.Net.NetworkCredential("username", "password");

        rsClient.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

        byte[] result = null;

        string reportPath = "filepath/filename";  
        string format = "EXCEL"; 
        string historyID = null;
        string devInfo = @"<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>";

        string encoding = String.Empty; //"";

        string mimeType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; // Excel2010


        //string mimeType = "application/vnd.ms-excel"; // EXCEL

        string extension = "";
        Warning[] warnings = null;
        string[] streamIDs = null;
        ParameterValue[] parameters = new ParameterValue[1];
        parameters[0] = new ParameterValue();
        parameters[0].Name = "ReportDate";
        parameters[0].Value = "12/11/2013";


        RSExec.ExecutionInfo execInfo = new RSExec.ExecutionInfo();
        RSExec.TrustedUserHeader trustedUH = new TrustedUserHeader();
        RSExec.ExecutionHeader execHeader = new RSExec.ExecutionHeader();
        RSExec.ServerInfoHeader serverInfo = new ServerInfoHeader();

        execHeader = rsClient.LoadReport(trustedUH, reportPath, historyID, out serverInfo, out execInfo);

        rsClient.SetExecutionParameters(execHeader, trustedUH, parameters, "en-us", out execInfo);



        rsClient.Render(execHeader, trustedUH, format, devInfo, out result, out extension, out encoding, out mimeType, out warnings, out streamIDs);

        string filename = @"filepath\filename.xlsx";

        FileStream stream = File.OpenWrite(filename);
        stream.Write(result, 0, result.Length);
        stream.Close();

        Dts.TaskResult = (int)ScriptResults.Success;

为了使其作为已部署的程序包运行,进行了以下修订
由于部署的程序包无法引用配置文件,因此Web服务的绑定已在脚本任务中编码

解决方法:

您不能互换使用XLS和XLSX – 它们是完全不同的格式.

XLS是基于二进制的格式,XLSX是基于XML模式的格式 – 它们将是完全不同的文件类型.您可以自己测试 – 在Excel中创建一个XLS文件,将其重命名为XLSX,当您尝试打开它时它会出错.

SSRS EXCEL格式只能保存到XLS文件中.

SSRS 2012可以导出到XLSX,但您需要使用EXCELOPENXML格式,而不是EXCEL.
