How to enable SSL for SmtpClient in Web.config

二次信任 提交于 2019-11-26 19:59:54
问题 Is there a way to set the EnableSSL from the web.config? I could set this property in code, but that wouldn't work for the Simple Mail Web Event and other classes that uses the default Smtp Server. Any ideas? 回答1: For .NET 3 and earlier: You can't. You have to manage it by hand. For more information you can see https://blogs.msdn.microsoft.com/vikas/2008/04/29/bug-asp-net-2-0-passwordrecovery-web-control-cannot-send-emails-to-ssl-enabled-smtp-servers/. For .NET 4: You can.

How to set username and password for SmtpClient object in .NET?

巧了我就是萌 提交于 2019-11-26 17:59:29
问题 I see different versions of the constructor, one uses info from web.config, one specifies the host, and one the host and port. But how do I set the username and password to something different from the web.config? We have the issue where our internal smtp is blocked by some high security clients and we want to use their smtp server, is there a way to do this from the code instead of web.config? In this case how would I use the web.config credentials if none is available from the database, for

C# sending mails with images inline using SmtpClient

安稳与你 提交于 2019-11-26 15:52:41
SmtpClient() allows you to add attachments to your mails, but what if you wanna make an image appear when the mail opens, instead of attaching it? As I remember, it can be done with about 4 lines of code, but I don't remember how and I can't find it on the MSDN site. EDIT: I'm not using a website or anything, not even an IP address. The image(s) are located on a harddrive. When sent, they should be part of the mail. So, I guess I might wanna use an tag... but I'm not too sure, since my computer isn't broadcasting. One solution that is often mentioned is to add the image as an Attachment to the

SmtpClient with Gmail

孤者浪人 提交于 2019-11-26 15:47:50
问题 I'm developing a mail client for a school project. I have managed to send e-mails using the SmtpClient in C#. This works perfectly with any server but it doesn't work with Gmail. I believe it's because of Google using TLS. I have tried setting EnableSsl to true on the SmtpClient but this doesn't make a difference. This is the code I am using to create the SmtpClient and send an e-mail. this.client = new SmtpClient("smtp.gmail.com", 587); this.client.EnableSsl = true; this.client
