Operation.ParameterOrderString 属性

定义

命名空间:

System.Web.Services.Description

程序集:

System.Web.Services.dll

获取或设置可选的远程过程调用 (RPC) 签名，它将请求-响应或恳求-响应操作规范排序。

public:
 property System::String ^ ParameterOrderString { System::String ^ get(); void set(System::String ^ value); };

public string ParameterOrderString { get; set; }

member this.ParameterOrderString : string with get, set

Public Property ParameterOrderString As String

属性值

String

用单个空格分隔的 MessagePart 实例的名称列表。

示例

String^ myString = nullptr;
Operation^ myOperation = gcnew Operation;
myDescription = ServiceDescription::Read( "Operation_2_Input_CS.wsdl" );
array<Message^>^myMessage = gcnew array<Message^>(myDescription->Messages->Count);

// Copy the messages from the service description.
myDescription->Messages->CopyTo( myMessage, 0 );
for ( int i = 0; i < myDescription->Messages->Count; i++ )
{
   array<MessagePart^>^myMessagePart = gcnew array<MessagePart^>(myMessage[ i ]->Parts->Count);

   // Copy the message parts into a MessagePart.
   myMessage[ i ]->Parts->CopyTo( myMessagePart, 0 );
   for ( int j = 0; j < myMessage[ i ]->Parts->Count; j++ )
   {
      myString = String::Concat( myString, myMessagePart[ j ]->Name, " " );
   }
}

// message part names.
myOperation->ParameterOrderString = myString;
array<String^>^myString1 = myOperation->ParameterOrder;
int k = 0;
Console::WriteLine( "The list of message part names is as follows:" );
while ( k < 5 )
{
   Console::WriteLine( myString1[ k ] );
   k++;
}

string myString = null ;
Operation myOperation = new Operation();
myDescription = ServiceDescription.Read("Operation_2_Input_CS.wsdl");
Message[] myMessage = new Message[ myDescription.Messages.Count ] ;

// Copy the messages from the service description.
myDescription.Messages.CopyTo( myMessage, 0 );
for( int i = 0 ; i < myDescription.Messages.Count; i++ )
{
   MessagePart[] myMessagePart =
      new MessagePart[ myMessage[i].Parts.Count ];

   // Copy the message parts into a MessagePart.
   myMessage[i].Parts.CopyTo( myMessagePart, 0 );
   for( int j = 0 ; j < myMessage[i].Parts.Count; j++ )
   {
      myString += myMessagePart[j].Name;
      myString += " " ;
   }
}
// Set the ParameterOrderString equal to the list of
// message part names.
myOperation.ParameterOrderString = myString;
string[] myString1 = myOperation.ParameterOrder;
int k = 0 ;
Console.WriteLine("The list of message part names is as follows:");
while( k<5 )
{
   Console.WriteLine( myString1[k] );
   k++;
}

Dim i As Integer
For i = 0 To myDescription.Messages.Count - 1
   Dim myMessagePart(myMessage(i).Parts.Count) As MessagePart

   ' Copy the message parts into a MessagePart.
   myMessage(i).Parts.CopyTo(myMessagePart, 0)
   Dim j As Integer
   For j = 0 To (myMessage(i).Parts.Count) - 1
      myString += myMessagePart(j).Name
      myString += " "
   Next j
Next i

' Set the ParameterOrderString equal to the list of 
' message part names.
myOperation.ParameterOrderString = myString
Dim myString1 As String() = myOperation.ParameterOrder
Dim k As Integer = 0
Console.WriteLine("The list of message part names is as follows:")

   Console.WriteLine(myString1(k))
   k += 1
End While

注解

命名 MessagePart 实例必须遵守以下规则：

• 命名 MessagePart 实例的顺序反映了 RPC (远程过程调用) 签名中参数的顺序，该签名是操作的名称、其输入和输出参数、它返回的结果以及可能需要处理的异常。

• 返回值不在列表中。

• 如果名称 MessagePart 同时出现在输入和输出消息中，则它是一个 in/out 参数。

• 如果名称 MessagePart 仅出现在输入消息中，则它是一个 in 参数。

• 如果名称 MessagePart 仅显示在输出消息中，则它是一个 out 参数。

请注意，此参数列表不是必需的，即使 Operation 要与 RPC 样式 Binding结合使用。 不要直接调用 ParameterOrderString 。 此方法仅在内部用于 XML 序列化。 若要返回参数列表，请使用 ParameterOrder。
