System.String类实现IEnumerable,但 PowerShell 不枚举字符串对象。 在以下示例中,通过管道将数组和哈希表传递给Measure-Objectcmdlet,以计算从管道接收的对象数。 数组具有多个成员,哈希表具有多个键值对。 一次只枚举一个数组。 PowerShell @(1,2,3) |Measure-Object ...
string message = "Hello,server!"; byte[] data = Encoding.ASCII.GetBytes(message); stream.Write(data, 0, data.Length); Console.WriteLine("Sent:" + message); // 接收数据 data = new byte[1024]; int bytesRead = stream.Read(data, 0, data.Length); string response = Encoding.ASCII.GetS...
