NegotiateStream.CanRead 属性

定义

命名空间:

System.Net.Security

程序集:

netstandard.dll, System.Net.Security.dll

Source:

NegotiateStream.cs

获取一个 Boolean 值，该值指示基础流是否可读。

C#

public override bool CanRead { get; }

属性值

Boolean

如果已进行身份验证且基础流为可读，则为 true；否则为 false。

示例

下面的代码示例演示如何显示此属性的值。

C#

 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

如果身份验证成功，此属性将返回通过调用 CanRead 基础流上的 属性返回的值。 基础流是在创建 类的 NegotiateStream 实例时指定的。
