C＃ 39. Conversion between string type and byte[] type (actual measurement)

    byte[] byteArray0 = System.Text.Encoding.Default.GetBytes("01A China ");
    byte[] byteArray1 = System.Text.Encoding.ASCII.GetBytes("01A China ");
    string str01 = System.Text.Encoding.Default.GetString(byteArray0);
    string str02 = System.Text.Encoding.ASCII.GetString(byteArray0);
    string str11 = System.Text.Encoding.Default.GetString(byteArray1);
    string str12 = System.Text.Encoding.ASCII.GetString(byteArray1);

So it's commonly used

byte[] byteArray0 = System.Text.Encoding.Default.GetBytes("01A China ");
string str01 = System.Text.Encoding.Default.GetString(byteArray0);
