.net - 在 VB.NET 中接受自签名 TLS/SSL 证书

Question

我正在寻找一种使用 VB.NET 验证(或绕过验证)自签名 SSL 证书的方法。我在 C# 中找到了执行此操作的代码，并尝试将其转换为 VB 代码，但我没有任何运气。

这是 C# 代码:How do I use WebRequest to access an SSL encrypted site using https?

这是我尝试过的:

Imports System
Imports System.Net
Imports System.Security.Cryptography.X509Certificates

Public Class clsSSL
    Public Function AcceptAllCertifications(ByVal sender As Object, ByVal certification As System.Security.Cryptography.X509Certificates.X509Certificate, ByVal chain As System.Security.Cryptography.X509Certificates.X509Chain, ByVal sslPolicyErrors As System.Net.Security.SslPolicyErrors) As Boolean
        Return True
    End Function
End Class

然后在 WebRequest 之前我有这行代码，它给我一个错误。

ServicePointManager.ServerCertificateValidationCallback =
    New System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications)

错误信息是:

Delegate 'System.Net.Security.RemoteCertificateValidationCallback' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.

Answer 1

在VB.Net中，你需要这样写

ServicePointManager.ServerCertificateValidationCallback = AddressOf AcceptAllCertifications
