Question

我有一个使用ClaimsIdentity的Webforms应用程序（不是MVC）。我想动态切换连接字符串，但是我看不到这样做的方法。我在网上看到的所有引用此内容的内容似乎都与MVC有关。这是我的代码：

Dim userStore As New UserStore(Of IdentityUser)
Dim roleStore As New RoleStore(Of IdentityRole)
Dim userManager As New UserManager(Of IdentityUser)(userStore)
Dim roleManager As New RoleManager(Of IdentityRole)(roleStore)

Dim userName As String = identity.Claims.First(Function(claim) claim.Type = ClaimTypes.WindowsAccountName).Value

无论如何，是否可以更改我正在使用的连接字符串，而不是Web.config文件中找到的DefaultConnection字符串？

我尝试创建此类，以派生自：

Imports System.Data.Entity
Imports Application.Common
Imports Application.Data.Migrations
Imports Application.Models
Imports Microsoft.AspNet.Identity.EntityFramework

Namespace Application.Data
    Public Class ApplicationDbContext
        Inherits IdentityDbContext(Of IdentityUser)

        Public Sub New(ByVal stringName As String)
            MyBase.New(stringName, throwIfV1Schema:=False)
        End Sub


        Public Shared Function Create(ByVal stringName As String) As ApplicationDbContext
            Return New ApplicationDbContext(stringName)
        End Function

        Public Overloads Function [Set](Of TEntity As Class)() As IDbSet(Of TEntity)
            Return MyBase.[Set](Of TEntity)()
        End Function
    End Class
End Namespace

然后，我这样做：

Dim newContext As ApplicationDbContext = New ApplicationDbContext("test")

Dim userStore As New UserStore(newContext)
Dim roleStore As New RoleStore(newContext)
Dim userManager As New UserManager(Of IdentityUser)(userStore)
Dim roleManager As New RoleManager(Of IdentityRole)(roleStore)

但是，错误“对'UserStore'的争论不休...”的变量userStore和RoleStore

像这样创建经理很成功：

 Dim userStore = New UserStore(Of IdentityUser)(New ApplicationDbContext("DefaultConnection1"))
 Dim roleStore = New RoleStore(Of IdentityRole)(New ApplicationDbContext("DefaultConnection1"))

您可以创建一个IdentityDbContext实例并通过构造函数设置ConnectionString，然后使用该实例创建UserStore和RoleStore，最后使用它们来创建UserManager和{{1 }}。

我对RoleManager不太擅长，这就是我在VB中的意思
