如何使用c#填充word模板

我试图填充具有合并字段的单词模板，当我运行应用程序时，它从现有模板生成一个单词文件，但字段未填充。没有错误。我不知道为什么它对我不起作用

代码如下:

    protected void Button2_Click(object sender, EventArgs e)
    {
        //OBJECT OF MISSING "NULL VALUE"
        Object oMissing = System.Reflection.Missing.Value;
        Object oTemplatePath = "C:''Users''pca''Desktop''temp1.dotx";

        Application wordApp = new Application();
        Document wordDoc = new Document();
        wordDoc = wordApp.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);
        foreach (Field myMergeField in wordDoc.Fields)
        {

            Range rngFieldCode = myMergeField.Code;
            String fieldText = rngFieldCode.Text;

            if (fieldText.StartsWith("MERGEFIELD"))
            {

                Int32 endMerge = fieldText.IndexOf("''");
                Int32 fieldNameLength = fieldText.Length - endMerge;
                String fieldName = fieldText.Substring(11, endMerge - 11);
                // GIVES THE FIELDNAMES AS THE USER HAD ENTERED IN .dot FILE
                fieldName = fieldName.Trim();
              if (fieldName == "Name")
                {
                    myMergeField.select();
                    wordApp.selection.TypeText("amal");
                }
            }
        }
        wordDoc.SaveAs("myfile1.docx");
        wordApp.Documents.Open("myFile1.docx");
        //wordApp.Application.Quit();
    }
