What Does The Error “‘property Cannot Be Assigned” Indicate When Trying To Send An SMTP Email Using C#?

In C#, the error message "’property cannot be assigned" typically occurs when you try to assign a value to a property that is read-only or does not have a setter defined.

When it comes to sending an email using SMTP in C#, certain properties of the SmtpClient class, such as Host, Port, Credentials, EnableSsl, etc., need to be set to appropriate values for the email to be sent successfully. However, if you receive the error "’property cannot be assigned" while trying to set these properties, it could be due to one of the following reasons:

  1. Read-only Property: Ensure that you are not trying to assign a value to a property that is read-only. Check the documentation of the SmtpClient class or the property in question to verify if it can be modified or not.

  2. Property Without Setter: Some properties in the SmtpClient class might not have a setter defined, meaning you cannot assign a value to them directly. In such cases, you need to initialize or configure the property through a different approach or method provided by the class.

  3. Incorrect Usage: Verify that you are using the correct syntax to assign a value to the property. Ensure that the property name is correctly spelled and that you are providing a valid value of the appropriate type.

To further investigate the specific cause of the error, it would be helpful to provide the code snippet that you are using to send the email via SMTP.
