我得到错误的地方是edit_user.aspx.vb的代码:

The code for the edit_user.aspx.vb is which is where I am getting the error:

Partial Class FamilyAdmin_edit_user
    Inherits System.Web.UI.Page

    Private username As String

    Private Sub Page_Load()
        username = Request.QueryString("username")
        If username Is Nothing OrElse username = "" Then
            Response.Redirect("users.aspx")
        End If
        User = Membership.GetUser(username)

        UserUpdateMessage.Text = ""
    End Sub

    Protected Sub UserInfo_ItemUpdating(ByVal sender As Object, ByVal e As DetailsViewUpdateEventArgs)
        'Need to handle the update manually because MembershipUser does not have a
        'parameterless constructor  

        User.Email = DirectCast(e.NewValues(0), String)
        User.Comment = DirectCast(e.NewValues(1), String)
        User.IsApproved = CBool(e.NewValues(2))

        Try
            ' Update user info:
            Membership.UpdateUser(User)

            ' Update user roles:
            UpdateUserRoles()

            UserUpdateMessage.Text = "Update Successful."

            e.Cancel = True
            UserInfo.ChangeMode(DetailsViewMode.[ReadOnly])
        Catch ex As Exception
            UserUpdateMessage.Text = "Update Failed: " + ex.Message

            e.Cancel = True
            UserInfo.ChangeMode(DetailsViewMode.[ReadOnly])
        End Try
    End Sub

    Private Sub Page_PreRender()
        ' Load the User Roles into checkboxes.
        UserRoles.DataSource = Roles.GetAllRoles()
        UserRoles.DataBind()

        ' Disable checkboxes if appropriate:
        If UserInfo.CurrentMode <> DetailsViewMode.Edit Then
            For Each checkbox As ListItem In UserRoles.Items
                checkbox.Enabled = False
            Next
        End If

        ' Bind these checkboxes to the User's own set of roles.
        Dim userRoles__1 As String() = Roles.GetRolesForUser(username)
        For Each role As String In userRoles__1
            Dim checkbox As ListItem = UserRoles.Items.FindByValue(role)
            checkbox.Selected = True
        Next
    End Sub

    Private Sub UpdateUserRoles()
        For Each rolebox As ListItem In UserRoles.Items
            If rolebox.Selected Then
                If Not Roles.IsUserInRole(username, rolebox.Text) Then
                    Roles.AddUserToRole(username, rolebox.Text)
                End If
            Else
                If Roles.IsUserInRole(username, rolebox.Text) Then
                    Roles.RemoveUserFromRole(username, rolebox.Text)
                End If
            End If
        Next
    End Sub

    Private Sub DeleteUser(ByVal sender As Object, ByVal e As EventArgs)
        'Membership.DeleteUser(username, false); // DC: My apps will NEVER delete the related data.
        Membership.DeleteUser(username, True)
        ' DC: except during testing, of course!
        Response.Redirect("manage_members.aspx")
    End Sub

    Private Sub UnlockUser(ByVal sender As Object, ByVal e As EventArgs)
        ' Dan Clem, added 5/30/2007 post-live upgrade.

        ' Unlock the user.
        User.UnlockUser()

        ' DataBind the GridView to reflect same.
        UserInfo.DataBind()
    End Sub

End Class

问题出在用户上.但是我不知道该如何将其归类为新的东西.

The problem is with the User. But I don't know how to sort this as im new to all this.

任何帮助将不胜感激.

谢谢

推荐答案

因为您忘记定义MembershipUser即

Because you forgot to define MembershipUser i.e.

Partial Class FamilyAdmin_edit_user
     Inherits System.Web.UI.Page      
Private username As String      
Dim User As MembershipUser

Private Sub Page_Load()
.....

当前，它正在考虑以"System.Security.Principal.IPrincipal"中的User身份，而不是MembershipUser.

Currently it is considering User as in 'System.Security.Principal.IPrincipal' and not MembershipUser.
