HeaderGetValue(Encoding) Method

public string GetValue(
	Encoding encoding
)

Parameters

encoding  Encoding

The character encoding to use as a fallback.

Return Value

If the raw header value does not properly encode non-ASCII text, the decoder will fall back to a default charset encoding. Sometimes, however, this default charset fallback is wrong and the mail client may wish to override that default charset on a per-header basis.

By using this method, the client is able to override the fallback charset on a per-header basis.
