NegotiateStream.Length 属性

定义

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,指定基础流的长度。

例外

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("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。
