  • 發行項

Important

This article is based on the v3 Bot Framework SDK. If you are looking for current documentation version 4.6 or later of the SDK, see the conversational bots section.

You can set the optional TextFormat property to control how your message's text content is rendered.

Microsoft Teams supports the following formatting options:

TextFormat value Description
plain The text should be treated as raw text with no formatting applied at all.
markdown The text should be treated as Markdown formatting and rendered on the channel as appropriate; see Formatting text content for supported styles.
xml The text is simple XML markup; see Formatting text content for supported styles.

Formatting text content

Teams supports a subset of Markdown and XML (HTML) formatting tags.

The following limitations apply:

  • Text-only messages do not support table formatting.
