远程服务器返回错误：NotFound

问题描述：

我有一个Silverlight应用程序，它在我的asp.net应用程序中使用WCF服务。Silverlight应用程序以墨迹笔画的形式保存“绘画”。这些笔画的形式是xaml（可能很大），我将其转换为字符串并发送到服务以将字符串保存到sql server。（基本上做这个应用程序相同的类型http://msdn.microsoft.com/en-us/magazine/cc721604.aspx）。远程服务器返回错误：NotFound

这个工作，我可以看到我的服务方法正在打的时候，绘图是相对较小，但如果绘图变得很大，我得到这个伟大的错误和服务方法断点永远不会被击中。看起来我已经通过了一个规模门槛，但我无法弄清楚我是对的还是要改变什么才能解决问题。

我已经谷歌和SO没有成功，所以任何帮助将不胜感激。提前致谢。

我的服务：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
public class DrawingService: IDrawingService 
{ 
    #region IDrawingService Members 
    public bool SaveEvalAreaDrawing(int EvalAreaId, string xmlToSave) 
    { 
     return true; 
    } 

    public bool SaveEvalItemDrawing(int EvalItemId, string xmlToSave) 
    { 
     return true; 
    } 

    public string GetEvalAreaDrawing(int EvalAreaId, string xmlToSave) 
    { 

     return "you got the eval drawing!"; 
    } 

    public string GetEvalItemDrawing(int EvalItemId, string xmlToSave) 
    { 

     return "you got the eval item drawing!"; 
    } 

    #endregion 
}

我与服务的web.config asp.net应用

哪里是_actual_错误的内容，其所有的宏伟？ – 2011-03-03 19:43:01

@Mr。失望 - 对不起，没有发布，因为我读过它的一个非常普遍和无益的错误，但我会编辑我的文章。 – AGoodDisplayName 2011-03-03 19:56:24

答

尝试增加readerQuotas - 添加binding元素中该元素

<readerQuotas maxStringContentLength="2147483647" />

http://msdn.microsoft.com/en-us/library/ms731325.aspx

或者，它可能是maxArrayLength。图像可能被序列化为数组。 – RQDQ 2011-03-03 19:49:08

我们有一个赢家！非常感谢。 – AGoodDisplayName 2011-03-03 20:05:22

答

你尝试过打开WCF Tracing？我不确定这是否适用于Silverlight（鉴于Silverlight在本地硬盘方面存在很多安全限制），因此您可能需要设置一个简单的no silverlight客户端，并在打开诊断程序的情况下重新创建呼叫。

编辑：或者，可能是readerQuotas的的MaxArrayLength成员...
