C# 字符串轉字節數組

定義string變量為str,內存流變量為ms,比特數組為bt

1.字符串轉比特數組

(1)byte[] bt=System.Text.Encoding.Default.GetBytes("字符串");

(2)byte[] bt=Convert.FromBase64String("字符串");

2.字符串轉流

(1)MemoryStream ms=new MemoryStream(System.Text.Encoding.Default.GetBytes("字符串"));

(2)MemoryStream ms=new MemoryStream(Convert.FromBase64String("字符串"));

3.流轉比特數組

(1)byte[] bt=ms.ToArray();

(2)MemoryStream ms=new MemoryStream();ms.Write(bt,0,ms.Length);

4.流轉字符串

(1)string str=Convert.ToBase64String(ms.ToArray());

(2)string str=System.Text.Encoding.Default.GetString(ms.ToArray());

5.比特數組轉字符串

(1)string str=System.Text.Encoding.Default.GetString(bt);

(2)string str=Convert.ToBase64String(bt);

6.比特數組轉流

(1)MemoryStream ms=new MemoryStream(bt);

(2)MemoryStream ms=new MemoryStream();ms.Read(bt,0,bt.Lenght);
