vb compile error

Ronald Chandler 41

I am using Visual Studio Express 2013 and Visual Basic., Windows 10. The statement:
NetworkCredential MyCredentials = New NetworkCredential("username", "password")
will not compile. Error is "NetworkCredential is a type and cannot be used as an expression"
My imports are:
Imports System.Net.Mail
Imports System.Net.Mime
Imports System.Net
What am I missing?

Hi @Ronald Chandler ,
After Google has enabled a new security policy, you should use app passwords to connect to Gmail SMTP server.

Try Dim MyCredentials = New NetworkCredential("username", "password") or Dim MyCredentials As NetworkCredential = New NetworkCredential("username", "password").

My code:

Dim SmtpServer As New SmtpClient() Dim Email As New MailMessage() Dim MyCredentials = New NetworkCredential("username", "password")

Debug shows:
?MyCredentials
{System.Net.NetworkCredential}
Domain: ""
Password: "password"
SecurePassword: {System.Security.SecureString}
UserName: "username"

My code continued:

SmtpServer.Host = "smtp.gmail.com" SmtpServer.UseDefaultCredentials = False SmtpServer.Credentials = MyCredentials

Debug shows:
?SmtpServer.Credentials
{System.Net.NetworkCredential}
System.Net.NetworkCredential: {System.Net.NetworkCredential}

The "MyCredentals" works, but it does not transfer to the SmtpServer.Credentials. why not??

This site says that you need to use App Passwords now.
