visual-studio-2010 - 通过编程方式在 Silverlight 中编辑服务引用客户端配置文件

Question

我正在silverlight中创建一个应用程序。该应用程序的XAP文件夹包含ServiceReferencesClientConfig文件。我已经将该应用程序部署在网络服务器上，每当我从其他机器访问该网站时(http://192.168.1.15/SampleApplication/Login.aspx)，我想将该IP地址（192.168.1.15）写入ServiceReferencesClientConfig 之后应该将 Xap 文件下载到客户端。但我不知道以编程方式编辑 ServiceReferencesClientConfig 文件。（我想在更改部署应用程序的网络服务器的 IP 地址时进行更改，它应该自动更改 ServiceReferencesClientConfig，因此无需手动更改 ServiceReferencesClientConfig 文件。）

作为一个选项，您可以动态配置服务代理，更改默认构造函数以使用动态生成的端点和绑定，或使用工厂来执行相同操作：

public MyService()
        : base(ServiceEx.GetBasicHttpBinding(), ServiceEx.GetEndpointAddress<T>())
{
}



public static class ServiceEx
{
    private static string hostBase;
    public static string HostBase
    {
        get
        {
            if (hostBase == null)
            {
                hostBase = System.Windows.Application.Current.Host.Source.AbsoluteUri;
                hostBase = hostBase.Substring(0, hostBase.IndexOf("ClientBin"));
                hostBase += "Services/";
            }
            return hostBase;
        }
    }

    public static EndpointAddress GetEndpointAddress<TServiceContractType>()
    {
        var contractType = typeof(TServiceContractType);

        string serviceName = contractType.Name;

        // Remove the 'I' from interface names
        if (contractType.IsInterface && serviceName.FirstOrDefault() == 'I')
            serviceName = serviceName.Substring(1);

        serviceName += ".svc";

        return new EndpointAddress(HostBase + serviceName);
    }

    public static Binding GetBinaryEncodedHttpBinding()
    {
        // Binary encoded binding
        var binding = new CustomBinding(
           new BinaryMessageEncodingBindingElement(),
           new HttpTransportBindingElement()
           {
               MaxReceivedMessageSize = int.MaxValue,
               MaxBufferSize = int.MaxValue
           }
        );

        SetTimeouts(binding);

        return binding;
    }

    public static Binding GetBasicHttpBinding()
    {
        var binding = new BasicHttpBinding();
        binding.MaxBufferSize = int.MaxValue;
        binding.MaxReceivedMessageSize = int.MaxValue;

        SetTimeouts(binding);

        return binding;
    }
}
