How can I programmatically delete a line from a word document using c#?

Question

I have some code to find and replace fields in a word document with values from a dataset.

Word.Document oWordDoc = new Word.Document();
foreach (Word.Field mergeField in oWordDoc.Fields)
{
mergeField.Select();
oWord.Selection.TypeText( stringValueFromDataSet );
}

In some cases stringValueFromDataSet is empty, and in addition to inserting nothing, I want to actually delete the current line.

Any idea how I can do this?

Answer 1

OK this was ridiculously easy in the end.

oWord.Selection.TypeBackspace();//remove the field
oWord.Selection.TypeBackspace();//remove the line

Answer 2

Obviously, your answer works in your case. However in the general case (where the entire line cannot be removed using a backspace) the following can be used:

 private static object missing = System.Reflection.Missing.Value;

 /// <summary>
 /// Deletes the line in which there is a selection.
 /// </summary>
 /// <param name="application">Instance of Application object.</param>
 private void DeleteCurrentSelectionLine(_Application application)
 {
  object wdLine = WdUnits.wdLine;
  object wdCharacter = WdUnits.wdCharacter;
  object wdExtend = WdMovementType.wdExtend;
  object count = 1;

  Selection selection = application.Selection;
  selection.HomeKey(ref wdLine, ref missing);
  selection.MoveDown(ref wdLine, ref count, ref wdExtend);
  selection.Delete(ref wdCharacter, ref missing);
 }
