using System; using System.IO; using System.IO.MemoryMappedFiles; using System.Text;   namespace MemoryMappedFileClient {     class Program     {         static void Main(string[] args)         {             System.Threading.Thread.Sleep(1000);             MemoryMappedFile memoryAccessor = MemoryMappedFile.OpenExisting("ProcessCommunicationAccessor");//获取服务端定义的ProcessCommunicationAccessor名称的内存映射文件然后调用ReadArray方法读取到服务端写入的数据             using (var accessor = memoryAccessor.CreateViewAccessor())             {                 var buffer = new byte[999];                 var read = accessor.ReadArray(0, buffer, 0, buffer.Length);                 var str = Encoding.UTF8.GetString(buffer);                 Console.WriteLine(Environment.NewLine + "Accessor Read Val:" + str.ToString());             }             MemoryMappedFile memoryStream = MemoryMappedFile.OpenExisting("ProcessCommunicationStream");//获取服务端定义的ProcessCommunicationStream名称的内存映射文件然后调用ReadToEnd方法读取到服务端写入的数据             using (var stream = memoryStream.CreateViewStream())             {                 using (var reader = new StreamReader(stream))                 {                     var str = reader.ReadToEnd();                     Console.WriteLine(Environment.NewLine + "Stream Read Val:" + str + "\r\n");                 }             }             Console.ReadLine();           }     } }
