XtraReport.FromStream(Stream) Method

Loads the report definition data from the specified stream and creates a report object from it. The created report's class is also specified in the REPX data format.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v18.1.dll

Syntax

    Stream stream
)

Parameters

Type Name Description

The Stream object containing the REPX or XML data to load.

Returns

Type Description
XtraReport

An XtraReport class or its descendant of the type specified in the REPX or XML data.

Important

Deserialization of reports obtained from untrusted parties can trigger execution of malicious code that can either be directly embedded into the report definition, or contained in an external assembly referenced by the report.

To avoid this, we recommend that you use XML serialization instead of CodeDOM and prevent any untrusted third-party libraries from becoming available on the server.

When a reporting application is deployed under the Medium Trust permission level, XML serialization is the only option to save reports (CodeDOM serialization is not supported in such environment).

Use this method to create a report instance from the report definition data stored in the specified stream. Note, that to be able to create the report, this method should find the class type of the creating report (the report class's type name is stored in the REPX data header). This type is searched for in the following assemblies:

  1. in the assembly (represented by the .EXE or .DLL file) which produced the report definition data. Its path is also mentioned in the report definition's header;
  2. in the current assembly where the FromStream method is called from;
  3. in the assemblies referenced by the current assembly.

If this class type is not found, an instance of the XtraReport class is created.
