mail.To.Add（txtTo.Text）;
// mail.To.Add（您要发送同一封电子邮件的另一个电子邮件ID）;
mail.From = new MailAddress（ abc@xxx.com）;
mail.Subject = txtSubject.Text;
mail.Body = txtBody.Text;
mail.IsBodyHtml = true ;
SmtpClient smtp = new SmtpClient（）;
smtp.Host = smtp.gmail.com; // 或您的SMTP服务器地址
smtp.Credentials = new System.Net.NetworkCredential（ abc@xxx.com， abcd123）;
smtp.EnableSsl = true ;
smtp.Send（mail）;
Label1.Text = 已成功发送...;
clear（）;
txtBody.text =
< ; html >

请有人帮助我......！
解决方案
错误是由文本框中包含html引起的。
在ASPX页面的页面指令中添加以下内容
validateRequest =false
对于.Net 4.0，您可能还需要对您的网络配置进行更改
< httpruntime requestvalidationmode =2.0/>

In my asp page i write this code for sending mail
protected void Btn_SendMail_Click(object sender, EventArgs e)
{
MailMessage mail = new MailMessage();
mail.To.Add(txtTo.Text);
//mail.To.Add("Another Email ID where you wanna send same email");
mail.From = new MailAddress("abc@xxx.com");
mail.Subject = txtSubject.Text;
mail.Body = txtBody.Text;
mail.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
smtp.Credentials = new System.Net.NetworkCredential("abc@xxx.com", "abcd123");
smtp.EnableSsl = true;
smtp.Send(mail);
Label1.Text = "Sent Successfully...";
clear();
txtBody.text="
<html>
<head>
<title>Test </title>
</head>
<body>
<table>
<tr>
<td> USERName: </td>
<td>Password </td>
</tr>
</table>
</body>
</html>
"
But i got this error "
A potentially dangerous Request.Form value was detected from the client (txtBody="<html>
<head>
<tit...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

<head>
<tit...").

please some one help me......!
解决方案
The error is caused by having html in your text box.
In the page directivesin the ASPX page add the following
validateRequest="false"
For .Net 4.0 you may also need to make a change in your web config
<httpruntime requestvalidationmode="2.0" />
Have a look here too
