Examples

The following example demonstrates the use of this method.

// HTML data is available natively on the clipboard; if not, it 
// will be false.
bool IsHTMLDataOnClipboard = Clipboard.ContainsData(DataFormats.Html);

// If there is HTML data on the clipboard, retrieve it.
string htmlData;
if(IsHTMLDataOnClipboard)
{

    htmlData = Clipboard.GetText(TextDataFormat.Html);
}

' After this line executes, IsHTMLDataOnClipboard will be true if
' HTML data is available natively on the clipboard; if not, it 
' will be false.
Dim IsHTMLDataOnClipboard As Boolean = Clipboard.ContainsData(DataFormats.Html)

' If there is HTML data on the clipboard, retrieve it.
Dim htmlData As String
If IsHTMLDataOnClipboard Then

    htmlData = Clipboard.GetText(TextDataFormat.Html)

End If
