二進(jìn)制轉(zhuǎn)換成圖片:

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

C#中byte[]與string的轉(zhuǎn)換代碼:

System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding();byte[] inputBytes =converter.GetBytes(inputString);string inputString = converter.GetString(inputBytes);string inputString = System.Convert.ToBase64String(inputBytes);byte[] inputBytes = System.Convert.FromBase64String(inputString); FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read);

C# Stream 和 byte[] 之間的轉(zhuǎn)換:

public byte[] StreamToBytes(Stream stream) {byte[] bytes = new byte[stream.Length];stream.Read(bytes, 0, bytes.Length);// 設(shè)置當(dāng)前流的位置為流的開始stream.Seek(0, SeekOrigin.Begin);return bytes; }

將 byte[] 轉(zhuǎn)成 Stream:

public Stream BytesToStream(byte[] bytes) {Stream stream = new MemoryStream(bytes);return stream; }

將 Stream 寫入文件:

?

public void StreamToFile(Stream stream,string fileName) {// 把 Stream 轉(zhuǎn)換成 byte[]byte[] bytes = new byte[stream.Length];stream.Read(bytes, 0, bytes.Length);// 設(shè)置當(dāng)前流的位置為流的開始stream.Seek(0, SeekOrigin.Begin);// 把 byte[] 寫入文件FileStream fs = new FileStream(fileName, FileMode.Create);BinaryWriter bw = new BinaryWriter(fs);bw.Write(bytes);bw.Close();fs.Close(); }

?

從文件讀取 Stream:

public Stream FileToStream(string fileName) { // 打開文件FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read);// 讀取文件的 byte[]byte[] bytes = new byte[fileStream.Length];fileStream.Read(bytes, 0, bytes.Length);fileStream.Close();// 把 byte[] 轉(zhuǎn)換成 StreamStream stream = new MemoryStream(bytes);return stream; }

?
