调用WCF客户端时的keyNotFoundException [英] keyNotFoundException when calling WCF client

问题描述

大家好，我有一个非常简单的wcf服务应用程序，我写的。我已将服务引用添加到我的silverlight应用程序中。但是当我运行应用程序时，它给了我keynotfoundexception。它似乎是我在
IphotoInfoServiceClient上调用new的地方。如果有人可以帮助我，我将非常感激，因为这是我第一次将服务应用程序包含在silverlight应用程序中

 private void Button_Click_1（object sender， RoutedEventArgs e）
 {
 IphotoInfoServiceClient photoclient = new IphotoInfoServiceClient（）; 
 
照片photoinfo = new Photo（）; 
 photoinfo.Comments = commentBox.Text; 
 photoinfo.Submitter = NameBox.Text; 
 Debug.WriteLine（photoinfo.Comments）; 
 Debug.WriteLine（photoinfo.Submitter）; 
 
 if（commentBox.Text！= null&& NameBox.Text！= null）
 {
 photoclient.submitPhotoAsync（photoinfo）; 
} 
其他
 {
 MessageBox.Show（"抱歉，输入名称和评论，然后再次尝试发送"，"缺少姓名或评论"，MessageBoxButton.OK ）; 
} 
} 

命名空间photoServiceLibrary 
 {
 //这些是方法必须通过此接口实现
 [ServiceContract] 
公共接口IphotoInfoService 
 {
 [OperationContract] 
 void submitPhoto（Photo photoinfo）; 
 [OperationContract] 
 List< Photo> getPhotoInfo（）; 
 [OperationContract] 
 void RemovePhoto（string id）; 
 
 
} 
}

解决方案

如果您导航浏览器中的Web服务是否显示服务页面？

请记住在发布服务时更改服务的URL。

Hello everyone, i have a very simple wcf service application that i have written. I have added the service reference into my silverlight application. But when i run the application it gives me the keynotfoundexception. it seems to be where i call new on the IphotoInfoServiceClient. If anyone can help me out, i will greatly appreciate it, as it is my first time including a service application into a silverlight app

private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            IphotoInfoServiceClient photoclient = new IphotoInfoServiceClient();

            Photo photoinfo = new Photo();
            photoinfo.Comments = commentBox.Text;
            photoinfo.Submitter = NameBox.Text;
            Debug.WriteLine(photoinfo.Comments);
            Debug.WriteLine(photoinfo.Submitter);

            if (commentBox.Text != null && NameBox.Text != null)
            {
                photoclient.submitPhotoAsync(photoinfo);
            }
            else
            {
                MessageBox.Show("sorry, enter a name and comment, then trying sending again", "Missing name or comment", MessageBoxButton.OK);
            }
        }

    //these are the methods that must be implemented from this interface

        void submitPhoto(Photo photoinfo);
        [OperationContract]
        List<Photo> getPhotoInfo();

解决方案

If you navigate to the web service in a browser does the service page show?

Remember to change the url for the service when you publish it.
