成员资格user.TryParse()

有人知道对等词吗?

目前我正在做。。

Dim myUsers As New MembershipUserCollection
Dim myUser As MembershipUser
Dim RoleUsers() As String
RoleUsers = Roles.GetUsersInRole("User")

For Each x As String In RoleUsers
    Dim roleUser As MembershipUser
    roleUser = Membership.GetUser(x)
    If Not roleUser Is Nothing Then
        myUsers.Add(Membership.GetUser(x))
    End If
Next

只是想知道有没有什么。。

If MembershipUser.TryParse(Membership.GetUser(x),myUser) Then
    myUsers.Add(myUser)
End If

VB或C工作。
