Assembly: Microsoft.Office.Interop.Word (in microsoft.office.interop.word.dll)
After this method is applied, the range expands to include the new text.
If you use this method with a range that refers to an entire paragraph, the text is inserted after the ending paragraph mark (the text will appear at the beginning of the next paragraph). To insert text at the end of a paragraph, determine the ending point and subtract 1 from this location (the paragraph mark is one character).
However, if the range ends with a paragraph mark that also happens to be the end of the document, Microsoft Word inserts the text before the final paragraph mark rather than creating a new paragraph at the end of the document.
Also, if the range is a bookmark, Word inserts the specified text but does not extend the range or the bookmark to include the new text.
