Hi,

I need to validate email

I need to match only my company domain mails

If it not matches my company mail I don't want to send mail

ex:

mahesh.reddy@tcs.com //send mail

mahesh.reddy@infosys.com //don't send mail

All mails should match only one domain name (tcs.com)

public void CheckMailFomat()
{
    string s = "abc.def@abc.com"; 
}

Could you please help me

Use below condition.

public void CheckMailFomat()
{
    string s = "mahesh.reddy@tcs.com";
    if (s.Split('@')[1].ToLower() == "tcs.com")
    {
        // Send mail.
    }
    else
    { 
        // Don't send mail.
    } 
}

VB.Net

Public Sub CheckMailFomat()
    Dim s As String = "mahesh.reddy@tcs.com"
    If s.Split("@"c)(1).ToLower() = "tcs.com" Then
        ' Send mail.
    Else
        ' Don't send mail.
    End If
End Sub
