ExpressionMessageId Method

Creates a criterion to find messages, that have a message-id header, that contains specified value (contains the specified string in the text of the header). If the string to search is zero-length, this matches all messages that have a Message-ID header name regardless of the contents.

Syntax

C++

Copy

public static ICriterion MessageId(
	string messageId
)

Public Shared Function MessageId ( 
	messageId As String
) As ICriterion

public:
static ICriterion^ MessageId(
	String^ messageId
)

static member MessageId : 
        messageId : string -> ICriterion

Parameters

messageId String: Message id.

Return Value

ICriterion
New expression.

Remarks

Some servers (Yahoo) require the search argument to be in exactly the same format, as the email header value. It's incorrect behavior, but there is a workaround for it: you can use Headers collection:


            IMail email = ...
            Expression.MessageId(email.Headers["Message-ID"])
