OpenXml Reset Numbering Level

I want to create Word Document using OpenXml and create numbering level. I faced a problem when I want to start numbering Level.
To Solve this problem you need to create new instance from abstract number using function as below:

static Numbering AddAbstractNumbering(Numbering numbering1, int numberId,              int abstractNumber)       {           NumberingInstance numberingInstance6 = new NumberingInstance ()           {NumberID = numberId};                     AbstractNumId abstractNumId6 = new AbstractNumId() { Val = 1 };           numberingInstance6.Append(abstractNumId6,              new LevelOverride() {                     StartOverrideNumberingValue = new StartOverrideNumberingValue() { Val = 1 }              } );           numbering1.Append(numberingInstance6);           return numbering1;       }

and use this instance to add numbering level to your paragraph:

Paragraph paragraph2 = new Paragraph();       ParagraphProperties paragraphProperties1 = new ParagraphProperties();       ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "ListParagraph" };       NumberingProperties numberingProperties1 = new NumberingProperties();       NumberingLevelReference numberingLevelReference1 =                                               new NumberingLevelReference() { Val = 0 };       NumberingId numberingId1 = null;       if (isNumberingStart)       {              numberId++;              numbering1 = AddAbstractNumbering(numbering1, numberId);              isNumberingStart = false;        }        numberingId1 = new NumberingId() { Val = numberId };        numberingProperties1.Append(numberingLevelReference1);        numberingProperties1.Append(numberingId1);        paragraphProperties1.Append(paragraphStyleId1);        paragraphProperties1.Append(numberingProperties1);         paragraph2.Append(paragraphProperties1);
