I can add one textbox link but I need to add 3 or more to the subject line.

Microsoft.Office.Interop.Outlook.Application outlookApp = new Microsoft.Office.Interop.Outlook.Application();
           Microsoft.Office.Interop.Outlook.MailItem mailItem = outlookApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
           //  mailItem.Subject = "This is a Automatic Email";  // Hard code Subject line
           mailItem.Subject = txt_CHKR.Text; txt_PN.Text;  // Need Help here
           mailItem.To = "Email.Address.Here@gmail.com";

What I have tried:

error is on this line

//Add Subject
                 oMailItem.Subject = mailItem.Subject = txt_CHKR.Text; txt_PN.Text;

Hint: Why are there two = symbols in that line? There should only be one.

Subject for a mail item is a property. This means that you can (typically) query it or assign a single value to it. So if you want to assign multiple values which originate from different text boxes, you first need to concatenate them, one way or another, and then do the assignment.

For example, you can try the following

C#

mailItem.Subject = $"{txt_CHKR.Text} {txt_PN.Text}";

Not sure what you mean, but I suggest opening a new question to Q&A. Just remember to explain your goal and the issue you're facing.
