我已经尝试了一切，但它一直在给我这个信息，而所有信息都是正确的（我认为是这样）。
这是错误：
System.Net.Mail.SmtpException：地址的主机名无效：yakovmora1@gmail.com。System.ArgumentException：在索引 9 处找到无效的 Unicode 代码点。参数名称：System.Text.Normalization.Normalize 处的 strInput（String strInput，NormalizationForm normForm）
我在 ASPX.CS 中的代码是：
protected void Sbutton_Click(object sender, EventArgs e)
{
string Name = Request.Form["Name"];
string email = Request.Form["email"];
string message = Request.Form["Message"];
if (CheckFields(Name, email, message, ref Label1) == true)
{
try
{
MailMessage myEmail = new MailMessage()
{
Subject = "Message from website user: [" + Name + "]",
Body = "Email: " + email + Environment.NewLine + Environment.NewLine + message,
IsBodyHtml = false,
From = new MailAddress(email, Name),
};
myEmail.To.Add(new MailAddress("yakovmora1@gmail.com", "IsraeCoreLx"));
SmtpClient server = new SmtpClient();
server.Send(myEmail);
Label1.Text = "Message Sent";
}
catch (Exception ex)
{
Label1.Text = "error sending message <br/><br/>" + ex.ToString();
}
if (Label1.Text != "Message Sent")
{
Label1.Text = "trying again";
#region trying again
