定义

命名空间:

System.Runtime.Remoting.Messaging

程序集:

mscorlib.dll

设置与方法调用一起发送的标题。

public:
 static void SetHeaders(cli::array <System::Runtime::Remoting::Messaging::Header ^> ^ headers);

[System.Security.SecurityCritical]
public static void SetHeaders (System.Runtime.Remoting.Messaging.Header[] headers);

[<System.Security.SecurityCritical>]
static member SetHeaders : System.Runtime.Remoting.Messaging.Header[] -> unit

Public Shared Sub SetHeaders (headers As Header())

参数

headers

Header[]

一个由要随方法调用发送的标头组成的 Header 数组。

属性

SecurityCriticalAttribute

例外

SecurityException

直接调用方没有基础结构权限。

示例

以下示例代码演示了在逻辑线程上放置标头的简易性。

public ref class HelloService: public MarshalByRefObject
{
public:
   String^ HelloMethod( String^ name )
   {
      Console::WriteLine( "Hello {0}", name );
      return "Hello {0}",name;
   }


   [SecurityPermissionAttribute(SecurityAction::Demand, Flags=SecurityPermissionFlag::Infrastructure)]
   String^ HeaderMethod( String^ name, array<Header^>^arrHeader )
   {
      Console::WriteLine( "HeaderMethod {0}", name );
      
      //Header Set with the header array passed
      CallContext::SetHeaders( arrHeader );
      return "HeaderMethod {0}",name;
   }
};

public class HelloService : MarshalByRefObject
{
   public string HelloMethod(string name)
   {
      Console.WriteLine("Hello " + name);
      return "Hello " + name;
   }

         public string HeaderMethod(string name,Header[] arrHeader)
   {
      Console.WriteLine("HeaderMethod " + name);
      //Header Set with the header array passed
      CallContext.SetHeaders(arrHeader);
      return "HeaderMethod " + name;
   }
}

Public Class HelloService
   Inherits MarshalByRefObject

   Public Function HelloMethod(name As String) As String
      Console.WriteLine(("Hello " + name))
      Return "Hello " + name
   End Function 'HelloMethod

   <PermissionSet(SecurityAction.LinkDemand)> _
   Public Function HeaderMethod(name As String, arrHeader() As Header) As String
      Console.WriteLine("HeaderMethod " + name)
      'Header Set with the header array passed
      CallContext.SetHeaders(arrHeader)
      Return "HeaderMethod " + name
   End Function 'HeaderMethod
End Class
