本文以实例形式详细介绍了C#实现Stream与byte[]之间的转换的方法，分享给大家供大家参考之用。具体方法如下：

一、二进制转换成图片

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

二、C#中byte[]与string的转换代码

1.

System.Text.UnicodeEncoding converter = new System.Text.UnicodeEncoding(); byte[] inputBytes =converter.GetBytes(inputString); string inputString = converter.GetString(inputBytes);

2.

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

三、C# Stream 和 byte[] 之间的转换

1.将 Stream 转成 byte[]

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

2.将 byte[] 转成 Stream

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

四、Stream 和 文件之间的转换

将 Stream 写入文件

public void StreamToFile(Stream stream,string fileName) { // 把 Stream 转换成 byte[] byte[] bytes = new byte[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 = new FileStream(fileName, FileMode.Create); BinaryWriter bw = new BinaryWriter(fs); bw.Write(bytes); bw.Close(); fs.Close(); }

五、从文件读取 Stream

public Stream FileToStream(string fileName) { // 打开文件 FileStream fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read, FileShare.Read); // 读取文件的 byte[] byte[] bytes = new byte[fileStream.Length]; fileStream.Read(bytes, 0, bytes.Length); fileStream.Close(); // 把 byte[] 转换成 Stream Stream stream = new MemoryStream(bytes); return stream; }

六、Bitmap 转化为 Byte[]

Bitmap BitReturn = new Bitmap(); byte[] bReturn = null; MemoryStream ms = new MemoryStream(); BitReturn.Save(ms, System.Drawing.Imaging.ImageFormat.Png); bReturn = ms.GetBuffer();

相信本文所述对大家的C#程序设计有一定的借鉴价值。
