我不知道要实现您的解决方案的特定正则表达式，但我可以向您展示一种方法.

I don''t know about specific Regex to achieve to your solution but yeah I can show you a way.

string listofEmail = "[e-mail],[e-mail]";
//Count total no of Email in the list
        int totalEmail = listofEmail.Split(',').Count();
        Regex regex = new Regex(@"[A-Za-z0-9._%-]+@[a-zA-Z0-9.-]+\.[A-Za-z]{2,4}");
        int regexMatch = regex.Matches(listofEmail).Count;
//Count no of email with which regex matches
        if (totalEmail == regexMatch)
        {
            //Emails are correctly formatted
        }
        else
        {
            //Raise error on one or more email is incorrect in the list
        }

公共布尔isMultipleEmail(string strEmail)
{
string [] eid = strEmail.Split(''，'');
for(int i = 0; i< eid.Length; i ++)
{
字符串strRegex = @"^([a-zA-Z0-9 _ \-\\.] +)@ [a-z0-9-] +(\.[a-z0-9-] +)*(\.[ az] {2,3} [] *)

public bool isMultipleEmail(string strEmail)
{
string[] eid = strEmail.Split('','');
for (int i = 0; i < eid.Length; i++)
{
string strRegex = @"^([a-zA-Z0-9_\-\.]+)@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3}[ ]*)

;
正则表达式re =新正则表达式(strRegex);
如果(！(re.IsMatch(eid [i] .ToString())))
{
return(false);
}

}
return(true);
}


strEmail = textbox.text;

";
Regex re = new Regex(strRegex);
if (!(re.IsMatch(eid[i].ToString())))
{
return (false);
}

}
return (true);
}


strEmail=textbox.text;
