这是我在 Windows Phone 7 客户端上遇到的异常

对于 TransferMode.Buffered，MaxReceivedMessageSize 和 MaxBufferSize 必须是相同的值。参数名称：绑定元素

我什至尝试设置 TransferMode="Streamed" 但这没有帮助，我得到了同样的异常。你能帮帮我吗？我是否缺少 Web.config 文件的部分内容？

请帮忙！

【问题讨论】：

客户端的 MaxReceivedMessageSize 和 MaxBufferSize 的值是多少？可能是您的手机（客户端）上的设置不匹配，而不是服务。
你能发布完整的Exception.ToString() 值吗？
我遇到了同样的问题，从客户端完全删除了 WCF 服务引用并再次添加它。问题已解决。希望这会有所帮助。

【解决方案1】：

问题可能是在客户端产生的。检查 WP7 应用上的 ServiceReferences.ClientConfig 文件并检查绑定。

它们应该是这样的：

<bindings> 
  <basicHttpBinding> 
    <binding name="{YOUR SERVICE NAME HERE" 
             maxBufferSize="2147483647" 
             maxReceivedMessageSize="2147483647"> 
  <security mode="None" /> 
</binding>

您需要确保maxBufferSize 和maxReceivedMessageSize 与服务器配置中的值相同。

【解决方案2】：

我遇到了同样的问题。我不知道这是否是 WP7 Silverlight 运行时中的错误，但是如果绑定是在代码中而不是在 ServiceReferences.ClientConfig 中定义的，它可以正常工作。像这样的：

var client = new MyServiceClient(
    new BasicHttpBinding( BasicHttpSecurityMode.None )
    {
        MaxReceivedMessageSize = 2147483647,
        MaxBufferSize = 2147483647
    },
    new EndpointAddress( yourAddress ) );

我还不知道这是什么原因。
