I think you are missing the 'aDoc' initialization. Try the following code.

var appWord = new Application { Visible = false };
object oMissing = Missing.Value;
Document aDoc = appWord.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing);

Please revert back, if you face any issue.

Actually im already doing what you have said.below is my code:
Microsoft.Office.Interop.Word.ApplicationClass WordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

// give any file name of your choice.
string tempath = numberofpage;
RegexOptions options = RegexOptions.None;
Regex regex = new Regex(@"[ ]{2,}", options);
tempath = regex.Replace(tempath, @"");
tempath = tempath.Replace(" \\", "\\");
object fileName = tempath;
object readOnly = false;
object isVisible = true;

// the way to handle parameters you don't care about in .NET
object missing = System.Reflection.Missing.Value;
object objDNS = Microsoft.Office.Interop.Word.WdSaveOptions.wdDoNotSaveChanges;

// Make word visible, so you can see what's happening
//WordApp.Visible = true;
// Open the document that was chosen by the dialog
Microsoft.Office.Interop.Word.Document aDoc = WordApp.Documents.Open(ref fileName,
ref missing, ref readOnly, ref missing,
ref missing, ref missing, ref missing,
ref missing, ref missing, ref missing,
ref missing, ref isVisible);

Microsoft.Office.Interop.Word.WdStatistic stat = Microsoft.Office.Interop.Word.WdStatistic.wdStatisticPages;
count = aDoc.ComputeStatistics(stat, ref missing);

WordApp.Quit(ref objDNS, ref missing, ref missing);

aDoc = null;

WordApp = null;

GC.Collect();
