NegotiateStream.Length 属性

定义

命名空间:

System.Net.Security

程序集:

System.Net.Security.dll

Source:

NegotiateStream.cs

获取基础流的长度。

public:
 virtual property long Length { long get(); };

public override long Length { get; }

member this.Length : int64

Public Overrides ReadOnly Property Length As Long

属性值

Int64

Int64，指定基础流的长度。

例外

NotSupportedException

当基础流为 NetworkStream 时，不支持获取此属性的值。

示例

下面的代码示例演示如何显示此属性的值。

static void DisplayStreamProperties( NegotiateStream^ stream )
{
   Console::WriteLine( L"Can read: {0}", stream->CanRead );
   Console::WriteLine( L"Can write: {0}", stream->CanWrite );
   Console::WriteLine( L"Can seek: {0}", stream->CanSeek );
   try
   {
      
      // If the underlying stream supports it, display the length.
      Console::WriteLine( L"Length: {0}", stream->Length );
   }
   catch ( NotSupportedException^ ) 
   {
      Console::WriteLine( L"Cannot get the length of the underlying stream." );
   }

   if ( stream->CanTimeout )
   {
      Console::WriteLine( L"Read time-out: {0}", stream->ReadTimeout );
      Console::WriteLine( L"Write time-out: {0}", stream->WriteTimeout );
   }
}

 static void DisplayStreamProperties(NegotiateStream stream)
{
     Console.WriteLine("Can read: {0}", stream.CanRead);
     Console.WriteLine("Can write: {0}", stream.CanWrite);
     Console.WriteLine("Can seek: {0}", stream.CanSeek);
     try
     {
         // If the underlying stream supports it, display the length.
         Console.WriteLine("Length: {0}", stream.Length);
     } catch (NotSupportedException)
     {
             Console.WriteLine("Cannot get the length of the underlying stream.");
     }

     if (stream.CanTimeout)
     {
         Console.WriteLine("Read time-out: {0}", stream.ReadTimeout);
         Console.WriteLine("Write time-out: {0}", stream.WriteTimeout);
     }
}

注解

此属性返回通过调用 Length 基础流上的 属性返回的值。 如果基础流不可查找，则此属性通常会引发异常。 基础流的运行时类型确定引发的异常的运行时类型。
