mail.Subject = subject;

}
}
XAML:
<Entry Placeholder="Phone No" x:Name="Phone" />
<Button Text="Pick a file" x:Name="fileButton" Clicked="File"/>
<Label Text="This is FileName" x:Name="fileLabel"/>
<Button Text="Submit" Clicked="SendEmail" BackgroundColor="Crimson" TextColor="White" WidthRequest="100" />
I want to send an email with an attachment. If I remove the code for the attachment the email gets to the recipient. When I am using the code for the attachment the email is not sent. I don't know why....

Answer 1

It fails because at no point do you add a file to the attachment variable:
System.Net.Mail.Attachment attachment;
attachment = new System.Net.Mail.Attachment();
mail.Attachments.Add(attachment);

Answer 2

You need to add a file path to the parameters of the new System.Net.Mail.Attachment constructor:
attachment = new System.Net.Mail.Attachment("enter file path here");
However, there are other options as well. See this Microsoft documentation.
You can enter a Stream instead of a string (the file path).
I think the following might work for you:
attachment = new System.Net.Mail.Attachment(fileLabel.Text);
