如何获取DocVariable的变量名？

Question

I have a word document that is filled with DocVariables. What I am having trouble with is that I can't retrieve their names. What works for me now is this;

foreach(Field ff in aDoc.Fields)
{
    string txt = ff.Code.Text;
    //parse...
    //it returns {DOCVARIABLE PageCount \* MERGEFORMAT } but what I want is just PageCount.
}

I tried this;

foreach (Field ff in aDoc.Fields)
{
    if (ff.Type == WdFieldType.wdFieldDocVariable)
    {
        ff.Select();
        string s = ff.Result.Text;
    }
}

but it returns null. Can you please help me with this problem or is this what it should be like?

如果您知道了，如您所说的字符串{DOCVARIABLE PageCount \\* MERGEFORMAT } ，则可以执行以下操作：

string str = txt.substring(1, txt.IndexOf(" "));
