Use the SetRange method to resize an existing range in a Microsoft Office Word document.

Applies to: The information in this topic applies to document-level projects and VSTO Add-in projects for Word. For more information, see Features available by Office application and project type.

To reset an existing range

  1. Set an initial range starting with the first seven characters in the document.

    The following code example can be used in a document-level customization.

    object start = 0; 
object end = 7; 
Word.Range rng = this.Range(ref start,ref end);

    The following code example can be used in a VSTO Add-in. This code uses the active document.

    Word.Range rng = this.Application.ActiveDocument.Range(0, 7);

  2. Use SetRange to start the range at the second sentence and end it at the end of the fifth sentence.

    rng.SetRange(this.Sentences[2].Start, this.Sentences[5].End);
