调试看路径对不对

[bdmh]

提示是，文件正被另一个进程使用，检查代码是不是哪个流没有释放，或者有软件正在使用

because it is being used by another process.

吧pageload里那段去掉

[chengwangtianxia]

originalImage.Clone();
originalImage.Dispose();

我猜你这句的意思应该是要关闭吧？写错了，写成克隆了。改成下面：

originalImage.Clone();
originalImage.Dispose();

[chengwangtianxia]

晕，我直接拷贝，拷贝错了，应该是改成

originalImage.Close();
originalImage.Dispose();

[你们是不是在找BUG]

打開水龍頭不開。。亂費資源啊。。。

[ponyas]

在哥们啊
System.Drawing.Image originalImage = System.Drawing.Image.FromFile(Server.MapPath(lsrUlr));
originalImage就没有Close()方法

我就是要实现读出一张图片然后， 读出它的高和宽，然后从新上传一去把原来的刚读出的来的这张图片给替换掉
