Set Content

GemBox.Document enables you to easily set any part of a document's content using text content or some arbitrary document content (like single or multiple document elements).

For text content you can use one of the ContentRange.LoadText methods and for more complex content you can use ContentRange.Set method.

The following example shows how you can set text content with and without formatting and set paragraph content to a part of the document using the ContentRange object.

        var section = document.Sections[0];

        // Set the content for 1st paragraph using plain text.
        section.Blocks[0].Content.LoadText("Paragraph with plain text.");
