Hi, I need to upload rsc file (report part) programmatically, with c# to SQL Server Reporting Services, I know how to upload RDL files but not rsc. Here is how I able to upload RDL files: { SSRS.ReportingService2005 _rs = new ConsoleApplication2.SSRS.ReportingService2005(); _rs.Url = "http://localhost/ReportServer/ReportService2005.asmx"; _rs.Credentials = System.Net.CredentialCache.DefaultCredentials; FileStream fs = null; string ReportName = string.Empty; byte[] data = null; SSRS.DataSourceReference reff = null; fs = File.OpenRead(@"D:\Report_WIP.rsc"); data = new byte[fs.Length]; fs.Read(data, 0, (int)fs.Length); _rs.CreateReport("TestName", "/MSS Report Parts folder", true, data, null); //_rs.CreateResource("TestName", "/MSS Report Parts folder", true, data, "application/rs", null); fs.Close(); } I tried also CreateResource but I can't find out the .rsc extension mime-type. Thanks
