關閉Image.FromFile(filePath)開啟的檔案

兩種方法，思路一樣的，做哥拷貝。。不懂為什麼FromFile函數自己沒做。

1 string   filenameOf   =   @ "D:\images\dao.gif "; 
2 FileStream   fs   =   new   FileStream(filenameOf,FileMode.Open,   FileAccess.Read); 
3  int   byteLength   =   (int)fs.Length; 
4  byte[]   wf   =   new   byte[byteLength]; 
5 fs.Read(wf,0,byteLength); 
6 fs.Close(); 

1 Image   img   =   Image.FromStream(new   MemoryStream(wf)); 
2 this.pictureBox1.Image   =   img;
3 
4 Image   image   =   Image.FromFile(obj.FileName); 
5 Image   bmp   =   new   Bitmap(image); 
6 image.Dispose();   //這句話很重要 
7 pictureBox1.Image   =   bmp;
