试试使用二进制传输 --------------------编程问答-------------------- 将接收和发送数据改为二进制，定义一个字节（Byte）数组，数组维数是0-bytesTotal，然后保存在相应类型的文件中 --------------------编程问答-------------------- 将接收和发送数据改为二进制，定义一个字节（Byte）数组，数组维数是0-bytesTotal，然后保存在相应类型的文件中 --------------------编程问答-------------------- 二进制打开图片文件，装入字节数组，分包处理，发送处理，延时处理大体如此。
