我已经在VS2008/中添加了web服务的代理。NET 3.5解决方案。在构造客户端。net时会抛出以下错误:
在ServiceModel客户端配置部分中找不到引用合约“IMySOAPWebService”的默认端点元素。这可能是因为没有为您的应用程序找到配置文件，或者因为在客户端元素中没有找到与此契约匹配的端点元素。
搜索此错误告诉我在契约中使用完整的名称空间。这是我的app.config完整的命名空间:
<client>
<endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService"
binding="basicHttpBinding" bindingConfiguration="IMySOAPWebServicebinding"
contract="Fusion.DataExchange.Workflows.IMySOAPWebService" name="IMySOAPWebServicePort" />
</client>
我正在运行XP本地(我提到这是因为一些谷歌点击提到win2k3)
将app.config复制到app.exe。配置，所以这也不是问题。
有线索吗?
“如果在类库中调用服务，并从另一个项目调用类库，则可能出现此错误。”
在这种情况下，如果是winapp或web，则需要将WS配置设置包含到主项目app.config中。如果它是一个web应用程序，就配置它。这是即使使用PRISM和WPF/Silverlight的方式。”
是的，但是如果你不能改变主项目(例如Orchard CMS)，你可以在你的项目中保留WCF服务配置。
你需要用客户端生成方法创建一个服务助手:
public static class ServiceClientHelper
{
public static T GetClient<T>(string moduleName) where T : IClientChannel
{
var channelType = typeof(T);
var contractType = channelType.GetInterfaces().First(i => i.Namespace == channelType.Namespace);
var contractAttribute = contractType.GetCustomAttributes(typeof(ServiceContractAttribute), false).First() as ServiceContractAttribute;
if (contractAttribute == null)
throw new Exception("contractAttribute not configured");
//path to your lib app.config (mark as "Copy Always" in properties)
var configPath = HostingEnvironment.MapPath(String.Format("~/Modules/{0}/bin/{0}.dll.config", moduleName));
var configuration = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap { ExeConfigFilename = configPath }, ConfigurationUserLevel.None);
var serviceModelSectionGroup = ServiceModelSectionGroup.GetSectionGroup(configuration);
if (serviceModelSectionGroup == null)
throw new Exception("serviceModelSectionGroup not configured");
var endpoint = serviceModelSectionGroup.Client.Endpoints.OfType<ChannelEndpointElement>().First(e => e.Contract == contractAttribute.ConfigurationName);
var channelFactory = new ConfigurationChannelFactory<T>(endpoint.Name, configuration, null);
var client = channelFactory.CreateChannel();
return client;
}
}
并使用它:
using (var client = ServiceClientHelper.GetClient<IDefaultNameServiceChannel>(yourLibName)) {
... get data from service ...
}
详见本文。
There seem to be several ways to create/fix this issue. For me, the CRM product I am using was written in native code and is able to call my .NET dll, but I run into the configuration information needing to be at/above the main application. For me, the CRM application isn't .NET, so I ended up having to put it in my machine.config file (not where I want it). In addition, since my company uses Websense I had a hard time even adding the Service Reference due to a 407 Proxy Authentication Required issue, that to required a modification to the machine.cong.
代理解决方案:
为了让WCF服务引用工作，我必须从我的DLL的app.config复制信息到主应用程序配置(但对我来说是machine.config)。我还必须将端点信息复制到同一个文件中。一旦我这么做了，它就开始为我工作了。
