ReportExecutionService::Render Method (String^, String^, String^, String^, String^, array<Warning^>^, array<String^>^)
Applies To: SQL Server 2016 Preview
Processes a specific report and renders it in the specified format.
Assembly: ReportExecution2005 (in ReportExecution2005.dll)
public: array<unsigned char>^ Render( String^ Format, String^ DeviceInfo, [OutAttribute] String^% Extension, [OutAttribute] String^% MimeType, [OutAttribute] String^% Encoding, [OutAttribute] array<Warning^>^% Warnings, [OutAttribute] array<String^>^% StreamIds )
The format in which to render the report. This argument maps to a rendering extension. Supported extensions include XML, NULL, CSV, IMAGE, PDF, HTML4.0, HTML3.2, MHTML, EXCEL, and Word. A list of supported extensions may be obtained by calling the ListRenderingExtensions method.
An XML string that contains the device-specific content that is required by the rendering extension specified in the Format parameter. DeviceInfo settings must be passed as internal elements of a DeviceInfo XML element. For more information about device information settings for specific output formats, see Passing Device Information Settings to Rendering Extensions.
[out] The file extension corresponding to the output stream.
[out] The MIME type of the rendered report.
[out] The encoding used when report server renders the contents of the report.
[out] An array of Warning objects that describes any warnings that occurred during report processing.
[out] The stream identifiers. These IDs are passed to the RenderStream method. You can use them to render the external resources (images, etc.) that are associated with a given report.
If the IMAGE rendering extension is used, the method outputs an empty array in StreamIds.
Return ValueType: array<System::Byte>^
A Byte array of the report in the specified format.

Render renders a processed report associated with the report execution identified in the ExecutionInfo header. If no temporary snapshot exists for the processed report in the execution state, this method will execute the report (if all credential and parameter requirements are met), resulting in a temporary snapshot being created for the execution state. If the report is reprocessed because non-query parameter values have changed, a new temporary snapshot is created. For more information on execution state, see Identifying Execution State.
If the execution options are set to cache or execution snapshot, the call to Render may use an existing snapshot.
If the report is set to cache and the supplied parameter values and credentials match, the cached copy of the snapshot may be loaded instead of actually processing the report.
If credential and parameter requirements are not met, this method will return an error.
Subsequent calls to Render can be used to fetch additional pages of the report if the rendering extension supports specifying multiple pages.
A limitation of the Render method is that the output cannot be streamed, so the entire file must be in-memory.
Please see Identifying Execution State for a discussion of the execution life cycle, which includes a description of the steps necessary to load and render a report.
Legacy Code Example
To compile the following code example, you must reference the Reporting Services WSDL and import certain namespaces. For more information, see . The following code example renders a report in MHTML and saves it as an .mht file to disk.
