MemoryStream ms = newMemoryStream(bytes); ms.Position = 0; Image img = Image.FromStream(ms); ms.Close(); this.pictureBox1.Image

Two. Conversion code for byte[] and string in C #

1.

123	System.Text.UnicodeEncoding converter = newSystem.Text.UnicodeEncoding(); 　　byte[] inputBytes =converter.GetBytes(inputString); 　　stringinputString = converter.GetString(inputBytes);

2.

123	stringinputString = System.Convert.ToBase64String(inputBytes); 　　byte[] inputBytes = System.Convert.FromBase64String(inputString); FileStream fileStream = newFileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read);

Three. Conversion between C # Stream and byte[]

123456789101112131415161718

/// 将 Stream 转成 byte[]  public byte[] StreamToBytes(Stream stream) {     byte[] bytes = newbyte[stream.Length];     stream.Read(bytes, 0, bytes.Length);     // 设置当前流的位置为流的开始     stream.Seek(0, SeekOrigin.Begin);     returnbytes; }  /// 将 byte[] 转成 Stream  publicStream BytesToStream(byte[] bytes) {     Stream stream = newMemoryStream(bytes);     returnstream; }

Four. Conversion between Stream and file

Write Stream to File

1234567891011121314

publicvoidStreamToFile(Stream stream,stringfileName) {     // 把 Stream 转换成 byte[]     byte[] bytes = newbyte[stream.Length];     stream.Read(bytes, 0, bytes.Length);     // 设置当前流的位置为流的开始     stream.Seek(0, SeekOrigin.Begin);     // 把 byte[] 写入文件     FileStream fs = newFileStream(fileName, FileMode.Create);     BinaryWriter bw = newBinaryWriter(fs);     bw.Write(bytes);     bw.Close();     fs.Close(); }

Five. Reading Stream from a file

1234567891011121314

publicStream FileToStream(stringfileName) {                 // 打开文件     FileStream fileStream = newFileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read);     // 读取文件的 byte[]     byte[] bytes = newbyte[fileStream.Length];     fileStream.Read(bytes, 0, bytes.Length);     fileStream.Close();     // 把 byte[] 转换成 Stream     Stream stream = newMemoryStream(bytes);     returnstream;   }
