Microsoft.Office.Interop.Word.Application WApp; Microsoft.Office.Interop.Word.Document Wdoc;

WApp = new Microsoft.Office.Interop.Word.Application();
//Opening Word file
Thread.Sleep(5312);
Wdoc = WApp.Documents.Open(@"C:\Users\Doc.doc");
object start = 0;
object end = Wdoc.Characters.Count;
Range rng = Wdoc.Range(ref start, ref end);


int wordCount = Wdoc.Words.Count;
// Display retrieved (incomplete) text
rng.TextRetrievalMode.IncludeHiddenText = false;
rng.TextRetrievalMode.IncludeFieldCodes = false;

// Find phrase in text string
string WTest;

while (icount <= wordCount)
{
    WTest = Wdoc.Words[icount].Text.ToString();

    foreach(string element in Title)

        if (Title[i] == WTest)

            Assert.IsTrue(true);
