Import HTML to OneNote

Code Example: Import HTML to OneNote

Here is a sample C# code snippet that demonstrates the entire conversion process:

    Import(Stream, HtmlImportOptions)
    Import(string, HtmlImportOptions)
    
    var document = new Document("sample_without_html.one");
    document.Import("sample_for_add.html", new HtmlImportOptions());
    document.Save("sample_with_html.one");

    Import(Stream, HtmlImportOptions)
    Import(string, HtmlImportOptions)

    var document = new Document("sample_without_html.one");
    using (var htmlStream = new FileStream("sample_for_add.html", FileMode.Open))
    {
        document.Import(htmlStream, new HtmlImportOptions());
    }
    document.Save("sample_with_html.one"); 

    Import(Stream, HtmlImportOptions)
    Import(string, HtmlImportOptions)
    
    var document = new Document();
    document
        .Import(Path.Combine(dataDir, "sample1.html"))
        .Import(Path.Combine(dataDir, "sample2.html"))
        .Import(Path.Combine(dataDir, "sample3.html"));
    document.Save(Path.Combine(dataDir, "sample_SimpleMerge.one"));

To import .html files into .one format using C#, follow these steps:
1. Export HTML: Use the Export to HTML to generate an .html file.
2. Import HTML into OneNote: Use Aspose.Note for .NET to import the .html file into a .one file.

Each code example demonstrates a specific scenario for importing HTML content into OneNote:
- HTML to One Import from a File: This example shows how to import a single HTML file into a OneNote document using the file path. The process creates a .one file containing the imported content.
- HTML to One Import with Stream: This example uses a stream to read the HTML file and import it into a OneNote document. This approach is useful for scenarios where files are not accessed directly via their paths.
- HTML to Import Multiple Files into One: This code imports multiple HTML files into a single OneNote document (.one) and saves the merged result. First, a new Document is created. Then, multiple HTML files are added using the Import method. Finally, the combined content is saved in a new OneNote file (sample_SimpleMerge.one). This demonstrates how to consolidate multiple HTML files into one cohesive OneNote structure.
