PrintingSystemBase.ExportToMht(String) Method

Exports a document to the specified file path in MHT format.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Printing.v18.2.Core.dll


public void ExportToMht(
    string filePath
Public Sub ExportToMht(
    filePath As String


Name Type Description
filePath String

A String which specifies the file name (including the full path) for the created MHT file.


Once the document export has started, it will run until the resulting document is complete and cannot be interrupted or canceled in the process.

Use this method to export a document to an MHT file using its current MHT-specific export options.

These options are represented by the MhtExportOptions object returned by the ExportOptions.Mht property of a printing system's PrintingSystemBase.ExportOptions. This object provides the HtmlExportOptionsBase.CharacterSet, HtmlExportOptionsBase.ExportMode, HtmlExportOptionsBase.RemoveSecondarySymbols and other properties which are intended to specify parameters of the resulting MHT file.

If you want to ignore the current export options of a printing system, and use your specific settings when a document is exported to MHT, you should use the overloaded PrintingSystemBase.ExportToMht method with the options parameter.


This method overwrites any files present at the specified path that have the same file name without any warnings.
