(.NET Core C#) Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml.

Chilkat.Email email = new Chilkat.Email();

// At this point, a new email object has been instantiated, and it
// already has a Date header field containing the current date/time.
Debug.WriteLine("Date: " + email.EmailDateStr);

// We can also get the Date header like this:
Debug.WriteLine("Date: " + email.GetHeaderField("Date"));

// Load a .eml into the email object:
bool success = email.LoadEml("myEmlFiles/someEmail.eml");
if (success != true) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

// Show the Date that was in the .eml
Debug.WriteLine("Date: " + email.EmailDateStr);

// Now the Date header contains whatever was in the .eml
// Let's update it to the current system date/time..

Chilkat.CkDateTime dateTime = new Chilkat.CkDateTime();

dateTime.SetFromCurrentSystemTime();

success = email.SetDt(dateTime);
if (success != true) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

// Now show that the Date is the current system time:
Debug.WriteLine("Date: " + email.EmailDateStr);
Debug.WriteLine("Date: " + email.GetHeaderField("Date"));
