you can search text and replace that text font.

Microsoft.Office.Interop.Word._Application word;
Microsoft.Office.Interop.Word._Document document;
word = new Microsoft.Office.Interop.Word.Application();
word.Visible = true;
document = word.Documents.Open("C:\MyDocuments\Hello.doc");
document.Activate();
object findStr = "hello"; // Find Text in Word Document
            
while (word.Selection.Find.Execute(ref findStr))  //If Found...
 {
         //change font and format of matched words
         word.Selection.Font.Name = "Arial"; //change font to Arial
}
document.Close();

The problem is that text changes.  I do know the length and the pattern i'm looking for.

C*******C A********A ********C

Everything in the * are numbers which are not constant and change.  The only constant is the "C" and "A's" in the string.

I wrote the below code but its setting the font to the whole document.  Any idea how to resolve?

private void ReplaceFont(Microsoft.Office.Interop.Word.Document masterDoc)
{
    masterDoc.Application.Activate();
    masterDoc.Application.Selection.Find.ClearFormatting();
    masterDoc.Application.Selection.Find.MatchWildcards = true;
    masterDoc.Application.Selection.Find.Wrap = 
           Microsoft.Office.Interop.Word.WdFindWrap.wdFindContinue;
    masterDoc.Application.Selection.Find.Text = "C*C A*A *C";
    masterDoc.Application.Selection.Find.MatchWildcards = true;

    bool isFound = true;
    while (isFound == true)
    {
        isFound = masterDoc.Application.Selection.Find.Execute(ref missing, ref missing, 
                     ref missing, ref missing, ref missing, ref missing, ref missing,
                     ref missing, ref missing, ref missing, ref missing,
                     ref missing, ref missing, ref missing, ref missing);

                if (isFound == true)
                {
                    masterDoc.Application.Selection.Font.Name = "E-13B";
                }
            }
        }

    masterDoc.Application.Activate();
    masterDoc.Application.Selection.Find.ClearFormatting();

    masterDoc.Application.Selection.Find.Wrap = 
           Microsoft.Office.Interop.Word.WdFindWrap.wdFindContinue;

    masterDoc.Application.Selection.Find.MatchWildcards = true;

    object findStr = "C*C A*A *C";

    while (masterDoc.Selection.Find.Execute(ref findStr))  //If Found...
    {
         //change font and format of matched words
         masterDoc.Selection.Font.Name = "E-13B";

This was the fix

masterDoc.Application.Selection.Find.Text = "<C[0-9]*C A[0-9]*A [0-9]*C>";
