导出Datagridview到Word文档

我使用以下代码从DatagGridview导出选定行到Word文档。代码正在工作，但有一个问题。它首先导出最后一行，我无法找出一种方法来使它按顺序导出。例如，如果我选择行[0,1,2,3]，它将导出行[3]，而不是[2]和[1]。知道是什么问题吗?

public void WordDoc(string getfilename)
        {

            object FileName = getfilename;

            //Create word Application Object
            Word.Application word = new Word.Application();
            //Create word document Object
            Word.Document doc = null;
            //Create word Missing Object
            object missing = System.Type.Missing;
            object readOnly = false;
            object isVisible = false;
            // make visible Word application
            word.Visible = true;
            try
            {
                doc = word.Documents.Open(ref FileName, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing, ref missing, ref missing,
                ref missing, ref missing, ref missing);
                doc.Activate();
