C# 將位元組流轉換為圖片的執行個體方法

複製代碼 代碼如下:usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Drawing;
usingSystem.IO;
namespaceMicrosoft.Form.Base
{
classImageToByte
{
/// <summary>
/// 圖片轉換成位元組流
/// </summary>
/// <param name="img">要轉換的Image對象</param>
/// <returns>轉換後返回的位元組流</returns>
publicstaticbyte[] ImgToByt(Image img)
{
MemoryStream ms = newMemoryStream();
byte[] imagedata = null;
img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
imagedata = ms.GetBuffer();
returnimagedata;
}
/// <summary>
/// 位元組流轉換成圖片
/// </summary>
/// <param name="byt">要轉換的位元組流</param>
/// <returns>轉換得到的Image對象</returns>
publicstaticImage BytToImg(byte[] byt)
{
MemoryStream ms = newMemoryStream(byt);
Image img = Image.FromStream(ms);
returnimg;
}
//
/// <summary>
/// 根據圖片路徑返回圖片的位元組流byte[]
/// </summary>
/// <param name="imagePath">圖片路徑</param>
/// <returns>返回的位元組流</returns>
privatestaticbyte[] getImageByte(stringimagePath)
{
FileStream files = newFileStream(imagePath, FileMode.Open);
byte[] imgByte = newbyte[files.Length];
files.Read(imgByte, 0, imgByte.Length);
files.Close();
returnimgByte;
}
}
}
