Answer 1

You could try with:

_doc = _app.Documents.Add(ref _docName , ref _missing , ref _missing , ref _missing );

instead of

_doc = _app.Documents.Open(.......);

and then check if this line is correct:

if (f.Code.Text.IndexOf("MERGEFIELD  \"" + pMergeField + "\"") > -1) 

I have a functioning code that works in this way

        mailMerge = doc.MailMerge;         
        foreach (Word.MailMergeField f in mailMerge.Fields)         
        {    
             // Extract the name of the MergeField starting from the 11 character
             // and looking for the first space after the name 
             // (this means that you avoid MergeFields names with embedded spaces)
             string fieldName = f.Code.Text.Substring(11).Trim();
             int  pos = fieldName.IndexOf(' ');
             if (pos >= 0) fieldName = fieldName.Substring(0, pos).Trim();

             if (fieldName == pMergeField) 
             {
                   f.Select();                  
                   app.Selection.TypeText(pValue);  
             }

The final code I used and which works for me is as follows:

public static void TextToWord(string pWordDoc, string pMergeField, string pValue)
    {
        Object oMissing = System.Reflection.Missing.Value;
        Object oTrue = true;
        Object oFalse = false;
        Word.Application oWord = new Word.Application();
        Word.Document oWordDoc = new Word.Document();
        oWord.Visible = true;
        Object oTemplatePath = pWordDoc;
        oWordDoc = oWord.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);
        foreach (Word.Field myMergeField in oWordDoc.Fields)
        {
            Word.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);
                fieldName = fieldName.Trim();
                if (fieldName == pMergeField)
                {
                    myMergeField.Select();
                    oWord.Selection.TypeText(pValue);
                }
            }
        }
    }

This code is orignally from here.
