在.Net中调用Web服务时,绕过无效的SSL证书错误

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

// 导入System.Net.Security命名空间
using System.Net.Security;

// 创建证书有效性过滤器
using X509Certificate2;

// 从当前程序集中检索要使用的证书
X509Certificate2 clientCert2 = new X509Certificate2("Path/To/Your/ClientCert.pfx", "password");

// 创建一个新的IPolicyFilter
IPolicyFilter ipolicyFilter = new System.Net.Security.RemoteCertificateValidationCallback((sender2, certificate2, chain2, sslPolicyErrors) => true);

// 使用证书有效性过滤器，无需设置ServicePointManager.ServerCertificateValidationCallback
EndpointAddress serviceAddress = new EndpointAddress("https://yourwebservice.com/path/to/endpoint");
ChannelFactory<YourService> factory = new ChannelFactory<YourService>(serviceAddress);

// 创建一个IWCFServiceHost, 使用新的IPolicyFilter实例
using (IWCFServiceHost host2 = factory.CreateChannel())
{
    // 使用IWCFServiceHost访问Web服务
    host2.YourServiceMethod();
}
