[Up] C # mail transmission method of embodiment] [webMail

There are in C # send two kinds of messages, one is transmitted using webmail embodiment, another way is to use netmail transmitted when using these two send mail, if the public mail server (e.g. message 126 server, Sina's mail server) are required to be able to send authorization and authentication, if it is using Gmail, then there will be a number of restrictions such as sending e-mail every day. This is the result of 2 ways I passed the test code, simply e-mail user name and password can be modified to their own, but can also modify the mail server, mail server into its own configuration.

/// <Summary>
    /// In Email sent (with authentication using Microsoft's new recommended way)
    /// </ Summary>
    /// <param name = "strto"> Write In Email </ param>
    /// <param name = "strCc"> Cc In Email </ param>
    /// <param name = "strSubject"> title </ param>
    /// <param name = "strBody"> SUMMARY </ param>
    /// <param name = "UserName"> mailbox validate account (account number and configuration to the web.config as) </ param>
    /// <param name = "from"> mail sender, corresponds to the UserName </ param>
    /// <param name = "strErrorMsg" > error message </ param>
    /// <Returns> </ Returns>
