Regular expression for multiple emails in ASP.Net

In my application I validate emails; but we can give more than one email address separated with a semicolon (";"). How can I write the validation expression?

My emails look like this:

"sasidhar@yahoo.com;suryasasidhar@开发者_高级运维gmail.com;srinivas@gmail.com "

How can I write a regular expression for this?

Start with the basic email regex and then apply as follows:

<email regex>(;<email regex>)*

You can give this a try:

\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*([,;]\s*\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*)*
