C#实现Stream与byte[]之间的转换实例教程
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。
