关闭Image.FromFile(filePath)打开的文件

两种方法，思路一样的，做哥拷贝。。不懂为什么FromFile函数自己没做。

 

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(); //这句话很重要 7 pictureBox1.Image = bmp;
