.net - 如何以编程方式更改端点的身份配置？

Question

我正在尝试创建一个工具来以编程方式修改我的服务的 app.config 文件。代码是这样的，

string _configurationPath = @"D:\MyService.exe.config";
ExeConfigurationFileMap executionFileMap = new ExeConfigurationFileMap();
executionFileMap.ExeConfigFilename = _configurationPath;

System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(executionFileMap, ConfigurationUserLevel.None);
ServiceModelSectionGroup serviceModeGroup = ServiceModelSectionGroup.GetSectionGroup(config);

foreach (ChannelEndpointElement endpoint in serviceModeGroup.Client.Endpoints)
{
    if (endpoint.Name == "WSHttpBinding_IMyService")
    {
        endpoint.Address = new Uri("http://localhost:8080/");
    }
}

config.SaveAs(@"D:\MyService.exe.config");

但是我在更改端点的身份时遇到问题。

我想要这样的东西:

<identity>
     <userPrincipalName value="user@domain.com" />
</identity>

对于我的端点配置，但是当我尝试时:

endpoint.Identity = new IdentityElement(){
    UserPrincipalName = UserPrincipalNameElement() { Value = "user@domain.com" }
}

失败是因为属性 endpoint.Identity和 identityElement.UserPrincipalName是只读的(我不确定为什么，因为 entity.Address 不是只读的)

有什么方法可以绕过这个限制并设置身份配置吗？

这被确认为有效。好痛……

public static void ChangeClientEnpoint(string name, Uri newAddress)
    {
        System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        ServiceModelSectionGroup serviceModeGroup = ServiceModelSectionGroup.GetSectionGroup(config);
        ChannelEndpointElement existingElement = null;
        foreach (ChannelEndpointElement endpoint in serviceModeGroup.Client.Endpoints)
        {
            if (endpoint.Name == "BasicHttpBinding_IMembershipService")
            {
                existingElement = endpoint;
            }
        }
        EndpointAddress endpointAddress = new EndpointAddress(newAddress.ToString());
        var newElement = new ChannelEndpointElement(endpointAddress, existingElement.Contract)
        {
            BehaviorConfiguration = existingElement.BehaviorConfiguration,
            Binding = existingElement.Binding,
            BindingConfiguration = existingElement.BindingConfiguration,
            Name = existingElement.Name
            // Set other values
        };
        serviceModeGroup.Client.Endpoints.Remove(existingElement);
        serviceModeGroup.Client.Endpoints.Add(newElement);
        config.Save();
        ConfigurationManager.RefreshSection("system.serviceModel/client");
    }
