先我想把1.jpg 保存为2.jpg ,按我这样的写法为什么 不可以删除 1.jpg 文件呀??如何解决谢谢 img = Image.FromFile("1.jpg");
img.Save("2.jpg");
img.Dispose();
Delete("1.jpg");
img.Save("2.jpg");
img.Dispose();
Delete("1.jpg");
img已经Dispose了,错误提示是什么?
using System.IO;class Test
{
public static void Main()
{
string path = @"c:\temp\MyTest.txt";
string path2 = @"c:\temp2\MyTest.txt";
try
{
if (!File.Exists(path))
{
// This statement ensures that the file is created,
// but the handle is not kept.
using (FileStream fs = File.Create(path)) {}
} // Ensure that the target does not exist.
if (File.Exists(path2))
File.Delete(path2); // Move the file.
File.Move(path, path2);
Console.WriteLine("{0} was moved to {1}.", path, path2); // See if the original exists now.
if (File.Exists(path))
{
Console.WriteLine("The original file still exists, which is unexpected.");
}
else
{
Console.WriteLine("The original file no longer exists, which is expected.");
} }
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
}
}
img.Save("2.jpg");
img.Dispose();
GC.Collect ;
Delete("1.jpg");
可能有用,但不影响你尝试一下的意义.
