C# 如何使用gmail和yahoo从mvc中的应用程序发送邮件？,c#,asp.net-mvc,C#,Asp.net Mvc,这是我的应用程序，我需要在其中发送电子邮件。它可以与gmail一起使用。是否可以与yahoo mail一起使用？（如果from textbox具有@gmail.com，则必须转到smtp.gmail.com步进控制器；如果from textbox具有@yahoo.com，则必须转到smtp.mail.yahoo.com，是否可能？）我的控制器： using emailtest1.Models; using System.IO; using System.Net; us

不能逐个重写主机和端口属性。你必须提出一个条件：

if(model.Email.contains("@gmail.com")){
     smtp.Host = "smtp.gmail.com";
     smtp.Port = 587;
} else if(model.Email.contains("@yahoo.fr")) {
     smtp.Host = "smtp.mail.yahoo.com";
     smtp.Port = 587;
}

是的，但不是像你做的那样，当你做：

smtp.Host = "smtp.gmail.com";
smtp.Host = "smtp.mail.yahoo.com";

您正在覆盖SMTP

你能做的就是这样

    smtp.Port = 587;
    if (textbox.value.contains("@gmail.com"))
            smtp.Host = "smtp.gmail.com";
    ELSE (textbox.value.contains("@yahoo.com"))
             smtp.Host = "smtp.mail.yahoo.com";

在那之后，做工作……

澄清一下，是与雅虎发送电子邮件的问题，还是“我如何做到两者”的问题？如果是这样，您是否为您编写的语句尝试了if/else条件？（

如果文本框中有@gmail.com，则必须转到smtp.gmail.com，如果文本框中有@yahoo.com，则必须转到smtp.mail.yahoo.com
