| InvalidMessageContractException(String) | Initializes a new instance of the InvalidMessageContractException class using the specified message. |
| InvalidMessageContractException(SerializationInfo, StreamingContext) | Initializes a new instance of the InvalidMessageContractException class when deserializing from a stream into an object. |
| InvalidMessageContractException(String, Exception) | Initializes a new instance of the InvalidMessageContractException class that uses the specified message and inner exception. |
| Name | Description | |
|---|---|---|
| Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
| HelpLink | Gets or sets a link to the help file associated with this exception. (Inherited from Exception.) |
| HResult | Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.) |
| InnerException | Gets the Exception instance that caused the current exception. (Inherited from Exception.) |
| Message | Gets a message that describes the current exception. (Inherited from Exception.) |
| Source | Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.) |
| StackTrace | Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.) |
| TargetSite | Gets the method that throws the current exception. (Inherited from Exception.) |
| Name | Description | |

| GetBaseException | When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetObjectData | When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception.) |
| GetType | Gets the runtime type of the current instance. (Inherited from Exception.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |

| Name | Description | |
|---|---|---|
 | SerializeObjectState | Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.) |
The InvalidMessageContractException is thrown when custom attribute usage results in the generation of an invalid service description. For example, if a System.ServiceModel.MessageContractAttribute type has multiple parts with the same name, or a method has multiple parameters with the same name.
The following code example shows a contract and service that throws an InvalidMessageContractException that says operand appears more than once in the message.
[ServiceContract(Namespace = "http://contoso.com/IMath")]
public interface IMath
{
[OperationContract]
void Add(AddMessage a);
}
[MessageContract]
public class AddMessage
{
[MessageBodyMember(Name="operand")]
public int a;
[MessageBodyMember(Name = "operand")]
public int b;
}
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
