Question

目前我有这个

Public Class ApplicationDbContext
    Inherits IdentityDbContext(Of ApplicationUser)
    Public Sub New()
        MyBase.New("DefaultConnection", throwIfV1Schema:=False)
    End Sub

    Public Shared Function Create() As ApplicationDbContext
        Return New ApplicationDbContext()
    End Function

如何使用这样的方法连接到另一个连接字符串？

Answer 1

您可以向ApplicationDbContext添加新构造函数，并将connectionstring传递给IdentityDbContext类。 IdentityDbContext构造函数采用Name或ConnectionString，因此您可以通过构造函数传递其他连接字符串。有关详细信息，请参阅msdn

Imports System.Collections
Imports System.Collections.Generic
Imports System.Data
Imports System.Diagnostics
Public Class ApplicationDbContext
    Inherits IdentityDbContext(Of ApplicationUser)
    Public Sub New()
        MyBase.New("DefaultConnection", throwIfV1Schema := False)
    End Sub

    Public Sub New(connectionstring As String)
        MyBase.New("connectionstring")
    End Sub

    Public Shared Function Create() As ApplicationDbContext
        Return New ApplicationDbContext()
    End Function
End Class
