Log-in as local system administrator, launch visual studio and try. If you're getting the same problem, please run the application from another machine.

Try these steps:
1. In Windows Explorer, locate and select the folder C:\Users\AMIT.
2. Right-click the folder, and then click Properties.
3. In the Properties dialog box, click the Security tab.
4. On the Security tab, examine the list of users. If the Network Service account is not listed, add it.
5. In the Properties dialog box, click the Network Service user name, and in the Permissions for NETWORK SERVICE section, select the Read, Write, and Modify permissions. Click Apply, and then click OK.
try running the application if it works now.

Hi Amit,
Check your firewall and antivirus settings, whether it is not blocking the external communication.
Temporarily disable antivirus, firewall and run your application to test it.

Amit,

Code suggested by Muralidharan Sir should work perfectly and it's working, tested. I suggest you to put a breakpoint in your try block and navigate through the code to see which like of code is raising the error. I suspect you have an issue with reading the file.

Please let us know if it helps.

Just change the following in your code,

SmtpClient mysmptclient = new SmtpClient();
mysmptclient.EnableSsl = true;

Enabled SSL and used default constructor for smtpclient.
