我创建了一个简单的服务,只是为了在 Cent OS 中尝试 WCF。我在 Windows 中使用 MonoDevelop 创建了服务客户端,它运行良好。当我尝试在 CentO 上运行它(使用相同的配置文件)时,它会在构建客户端时引发错误,我在这里跟踪它:
ExtensionElementCollection extensions = ((ExtensionsSection) EvaluationContext.GetSection ("system.serviceModel/extensions")).BindingExtensions;
for (int i = 0; i < extensions.Count; i++) {
ExtensionElement extension = extensions [i];
_properties.Add (new ConfigurationProperty (extension.Name, Type.GetType (extension.Type), null, null, null, ConfigurationPropertyOptions.None));
}
在 System.ServiceModel.Configuration.BindingsSection
错误是 ConfigurationProperty 构造函数中的 argumentNullException,类型为 null。因此,EvaluationContext.GetSection ("system.serviceModel/extensions") 中的 Type.GetType 失败了。我在配置文件中没有扩展部分,并且这个相同的客户端在 Windows 中完美运行。任何提示。
这是我的配置文件:
