Namespace:  System.Web.Security
Assembly:  System.Web (in System.Web.dll)

public static MembershipUserCollection FindUsersByEmail(
	string emailToMatch
)

Parameters

emailToMatch
Type: System.String
The e-mail address to search for.

Return Value

Type: System.Web.Security.MembershipUserCollection
A MembershipUserCollection that contains all users that match the emailToMatch parameter.
Leading and trailing spaces are trimmed from the emailToMatch parameter value.

FindUsersByEmail returns a list of membership users where the e-mail address matches the supplied emailToMatch for the configured applicationName.

The SqlMembershipProvider performs its search using a LIKE clause against the emailToMatch parameter. Any wildcards that are supported by SQL Server in LIKE clauses can be used in the emailToMatch parameter value.

The following code example uses the FindUsersByEmail method to retrieve membership user information from the membership database based on user input and displays the results in pages of data.
