MailAddress Constructor (String, String, Encoding)

MailAddress Constructor (String, String, Encoding)


Initializes a new instance of the MailAddress class using the specified address, display name, and encoding.

Namespace:   System.Net.Mail
Assembly:  System (in System.dll)

public MailAddress(
	string address,
	string displayName,
	Encoding displayNameEncoding


Type: System.String

A String that contains an e-mail address.

Type: System.String

A String that contains the display name associated with address.

Type: System.Text.Encoding

The Encoding that defines the character set used for displayName.

Exception Condition

address is null.


displayName is null.


address is String.Empty ("").


displayName is String.Empty ("").


address is not in a recognized format.


address contains non-ASCII characters.

Leading and trailing white space in the display name is preserved.

If address contains a display name, and displayName is not null and is not equal to String.Empty, displayName overrides the value specified in address.

The MailAddress method does not check if the displayName parameter is valid. This method removes surrounding quotes not displayed by the DisplayName property. Quotes will be added before transmission, except where ASCII or Unicode is specified in the displayNameEncoding parameter. The encoding specified in the displayNameEncoding parameter will be applied to the DisplayName property before transmission ASCII or Unicode is specified in the displayNameEncoding parameter. UTF8 is the default encoding if none is specified.

For more information on supported mail address formats, see MailAddress.

The following code example uses this constructor to create MailAddress instances for the sender of an e-mail message.

// Create a mailing address that includes a UTF8 character
// in the display name.
MailAddress from = new MailAddress("", 
   "Jane " + (char)0xD8+ " Clayton",
