does revit api support to save exported ifc fiile in memory stream programatically

[gowtham_venkitusamy]

// Set up IFC export options file schema
IFCExportOptions exportOptions = new IFCExportOptions();
exportOptions.FileVersion = IFCVersion.IFC4RV;
exportOptions.AddOption("StoreIFCGUID", "true");
exportOptions.AddOption("VisibleElementsOfCurrentView", "true");
exportOptions.AddOption("ExportInternalRevitPropertySets", "true");
exportOptions.AddOption("ExportIFCCommonPropertySets", "true");
exportOptions.AddOption("TessellationLevelOfDetail", "0.25");

    MemoryStream ifcMemoryStream = new MemoryStream();

    bool exportSuccess = doc.Export(ifcMemoryStream, revitFileName, exportOptions);

Error :" doc.Export" this particular export automatically changed ifc export to gbxmlexport

Severity Code Description Project File Line Suppression State
Error CS1503 Argument 3: cannot convert from 'Autodesk.Revit.DB.IFCExportOptions' to 'Autodesk.Revit.DB.GBXMLExportOptions'

Short answer: 

• No.

Explanation of the behaviour you describe:

The document IFC export method taking an IFCExportOptions argument takes a string as its first argument, representing a file name:

• Export Method (String, String, IFCExportOptions) 
  https://www.revitapidocs.com/2024/7efa4eb3-8d94-b8e7-f608-3dbae751331d.htm

If you provide a non-string first argument, e.g., a MemoryStream, this overload cannot be found, so it picks an arbitrary one of the various Export overloads to tell you that you are making a mistake.

is revit api only supports to export ifc file to local in programatically or using revit i can able to export ifc file to cloud?

The built-in Revit IFC export is to a file on the hard disk. The entire IFC export functionality is open source, however, so you can tweak it to your needs:
