I want to recover the mergefield "OpenSDKXml, C# "

Question

I am using the sdk OpenXML for recovering the mergeField on document word, but the code recovered the body of mergeField: 

 

if (!string.IsNullOrEmpty(strFieldName))

 { //check if we have a value for this merge field 

  if (values.ContainsKey(strFieldName) && !string.IsNullOrEmpty(values[strFieldName]))

     { 

       objField.Parent.Parent.Parent.ReplaceChild<Paragraph>(new Run(new Text(values[strFieldName])),(Paragraph) objField.Parent.Parent);

     }

 }
