Byte|Stream|String测试操作

static void ByteTest()
{
byte[] namebytearray = System.Text.Encoding.UTF8.GetBytes("zzy");
string readstr = string.Empty;
Stream mstream = new MemoryStream(namebytearray);//字节数组转换成内存流
long length = mstream.Length;
byte[] bufferbyte = new byte[length];
mstream.Read(bufferbyte, 0, int.Parse(length.ToString()));//流读取到字节数组
string resultstr = Encoding.UTF8.GetString(bufferbyte);//字节数组转换成字符串
Console.WriteLine("流转换成字符串：" + resultstr);
using (StreamReader streamReader = new StreamReader(Environment.CurrentDirectory + "/test.txt"))
{
while (!streamReader.EndOfStream)
{
readstr += streamReader.ReadLine() + "\r\n";
}
}

Console.WriteLine("从文件读出来的字符串：\r\n" + readstr);
Console.ReadKey();
