正则表达式可以解决您的问题

Regular Expression can solve your problem

取值并验证IsNumeric()函数，并检查是否为真，您会发现它是否还有其他电子邮件号码.

Take the value and verify to IsNumeric() function, and check for true and false, u will find it whether it number else email.

您可以使用正则表达式来解析段落的内容，可以使用下面的代码，

Hi,
You can use regular expression to parse the content of paragraph, you can use the code below,

MatchCollection matchEmails=Regex.Matches(STRING_TO_MATCH, @"\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*", RegexOptions.Compiled | RegexOptions.Multiline);
MatchCollection matchPhones = Regex.Matches(STRING_TO_MATCH, @"[2-9]\d{2}-\d{3}-\d{4}", RegexOptions.Compiled | RegexOptions.Multiline);

您将在matchEmails中找到匹配的电子邮件，在matchPhones 中找到匹配的电话号码.

You will find matched emails in matchEmails and matched phone number in matchPhones .
