简单的正则表达式很容易:@"[^ \< \> ...]"，其中的省略号是您要禁止的单个字符的列表.

但是，我建议更好的电子邮件地址验证是一个好主意，尤其是因为"@"不是电子邮件地址中的合法字符(这是域名和域名之间的分隔符本地地址，并且不能用于其他任何原因):请查看此 [

The simple regex is easy: @"[^\<\>...]" where the elipsis is the list of individual characters you want to prohibit.

However, I would suggest that a better email address validation would be a good idea, especially since ''@'' is not a legal character in an email address (it is the separator between the domain and the local addresses and cannot be used for any other reason): have a look at this[^]
