什么不用多说就是一个方法大家直接看下代码吧
[C#] 纯文本查看 复制代码 /// <summary>
/// 发送邮件
/// </summary>
/// <param name="MailFromAddress">发件人地址</param>
/// <param name="MailFromUserName">用户名</param>
/// <param name="MailFormPwd">密码</param>
/// <param name="MailTitle">邮件标题</param>
/// <param name="MailBody">邮件内容</param>
/// <param name="MailTo">收件人地址</param>
/// <returns>发送成功返回True否则返回False</returns>
public static Boolean SendMail(string MailFromAddress, string MailFormPwd, string MailTitle, string MailBody, string MailTo)
{
try
{
MailMessage objMail = new MailMessage();
//发件人地址
objMail.From = new MailAddress(MailFromAddress);
//邮件标题
objMail.Subject = MailTitle;
//邮件标题编码
objMail.SubjectEncoding = System.Text.Encoding.UTF8;
//邮件内容
objMail.Body = MailBody;
//邮件内容编码
objMail.BodyEncoding = System.Text.Encoding.UTF8;
//收件人地址在这里可以加多个
objMail.To.Add(MailTo);
//用SMTP发送邮件的方式
SmtpClient client = new SmtpClient();
//用户名和密码
client.Credentials = new System.Net.NetworkCredential(MailFromAddress, MailFormPwd);
string StrMail = "";
for (int i = 0; i < MailFromAddress.Length; i++)
{
if (MailFromAddress.Substring(i, 1).ToString().Trim() == "@")
{
StrMail = MailFromAddress.Substring(i + 1, MailFromAddress.Length - i - 1);
}
}
//服务器名
client.Host = "smtp." + StrMail.ToString().Trim();
//发送
client.Send(objMail);
return true;
}
catch (Exception)
{
return false;
}
}
使用的方法也很简单
[C#] 纯文本查看 复制代码 MailMessage objMail = new MailMessage();
//发件人地址
objMail.From = new MailAddress(txtForm.Text.ToString().Trim());
//邮件标题
objMail.Subject = txttitle.Text.ToString().Trim();
//邮件标题编码
objMail.SubjectEncoding = System.Text.Encoding.UTF8;
//邮件内容
objMail.Body = txtBody.Text.ToString().Trim();
//邮件内容编码
objMail.BodyEncoding = System.Text.Encoding.UTF8;
//收件人地址在这里可以加多个
objMail.To.Add(txtTO.Text.ToString().Trim());
//用SMTP发送邮件的方式
SmtpClient client = new SmtpClient();
//用户名和密码
client.Credentials = new System.Net.NetworkCredential(txtForm.Text.ToString().Trim(), txtPwd.Text.ToString().Trim());
//服务器名
client.Host = "SMTP.163.com";
//发送
client.Send(objMail);
里面的MailMessage 大家自己写一下吧就是一个简单的实体类没什么特别之处
在这里呢多给大家提供两个发送邮件的类方法吧，大家可以做为参考
