如何在C＃Word Interop中指定范围之前确定行范围

Question

I have identified a range in a word document through identifying the range of a certain word using the following code:

object start = 0, end = 0;
Word.Range myRange = doc.Range(ref start, end);
if(myRange.Find.Execute("wordtofind"))
{
    //some codes here
}

I am wondering if there is a way I can find to get the range of a specific line in the document that is 3 lines/paragraphs before that "wordtofind"?

Note:

The "wordtofind" is the only word in that particular line where it can be found.

You can use the Range.MoveEnd method to move the Range "backwards" by a certain number of specified units (see the Word.WdUnits enumeration).

To move back 3 paragraphs:

object unitPara as Word.WdUnits.wdParagraph;
object moveBack3 = -3;
myRange.MoveEnd(ref unitPara, ref moveBack3);
