我对MVC比较陌生。想知道如何在登录期间验证用户的电子邮件地址。例如，具有以“gmail.com”结尾的电子邮件地址的用户必须被定向到不同的视图，而具有不同电子邮件的其他用户应被定向到不同的视图。我该怎么做呢？任何帮助将不胜感激

嗨检查这部分正则表达式部分我没有测试过。但你采用类似的方法
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.apache.logging.log4j.ThreadContext;
答案 1 :(得分：0)
如果您愿意，可以使用：
if (model.Email.toLower().contains("@gmail.com"))
{
// do something
}
在这种情况下，如果用户输入字符串＆＃34; @ gmail.com＆＃34;在他的电子邮件地址中间会出现一个小错误：）
或者这里的这条长线要好得多：
if (model.Email.toLower().LastIndexOf("@gmail.com") == (model.Email.Length - 11 /* the length of "@gmail.com" + 1 */ )
{
// do something
}
答案 2 :(得分：0)
试试这个
if (model.Email.ToLower().EndsWith("@gmail.com") && model.Email.Length > 10)
{
// do gmail stuff
}
