我尝试调用的方法具有以下签名:

结果GetPerformanceData(MyEntity实体,bool recurse);

我在方法的开头设置了一个断点,但是在代码执行到达断点之前抛出了异常.

跟踪WCF服务向我提供以下信息:

System.NullReferenceException,mscorlib,Version = 2.0.0.0,Culture = neutral,PublicKeyToken = b77a5c561934e089对象引用未设置为对象的实例.StackTrace:位于System.Runtime.Serialization.CodeGenerator.Call(Object thisObj,MethodInfo methodInfo,Object param1)的System.Runtime.Serialization.CodeGenerator.VerifyParameterCount(MethodInfo methodInfo,Int32 expectedCount)at ...

如何确定null变量是什么？我的调试器设置为中断所有异常,但它并没有打破这个特定的问题.看起来我试图调用的方法的"实体"参数无法正确反序列化.

示例调用调用

var results = client.GetPerformanceData(entity,true);
