file renaming problem?
在 C# 中重命名文件：
File.Move(source,Destination);
File.Delete(source);
foreach (string folder in folder)
{
FileSystemItem item = new FileSystemItem();
DirectoryInfo di = new DirectoryInfo(folder);
item.Name = di.Name;
item.FullName = di.FullName;
item.Path = path +"\" + item.Name;
item.CreatedDate = di.CreationTime;
item.IsFolder = true;
item.Extension ="folder";
listFolder.Add(item);
}
docList = CreatXmllist(listFolder);
return docList
public xml (string path, List<l> one)
{
List< T > tt = new List< T >();
List< T > SessionList = new List< T >();
string[] files = Directory.GetFiles(HttpContext.Current.Request.PhysicalApplicationPath + path);
foreach (string file in files)
{
FileSystemItem item = new FileSystemItem();
FileInfo i = new FileInfo(file);
string a = i.LastWriteTime.ToString();
var thumbnails = from a in b where a.Name == fi.Name select t;
if (fi.Name !="a")
if (t.Count() == 0)
{
r session r = new r();
r.aName = fi.aName;
SessionList.Add(r);
fi.Exists;
}
else
t.Add((T)t.First());
}
FileInfo file = new FileInfo(source);
file.MoveTo(destination);
// execute more code
file.MoveTo(destination2)它执行成功，但是当我再次尝试重命名文件时，系统给出了这个异常：
该进程无法访问该文件，因为它正被另一个进程使用。
我找不到这个在哪里使用？当我进一步调试错误时，它显示类名在 w3wp.exe 的进程中，即 IIS。接下来我该怎么办？
得到
File.Move(source,Destination);
File.Delete(source);
foreach (string folder in folder)
{
FileSystemItem item = new FileSystemItem();
DirectoryInfo di = new DirectoryInfo(folder);
item.Name = di.Name;
item.FullName = di.FullName;
item.Path = path +"\" + item.Name;
item.CreatedDate = di.CreationTime;
item.IsFolder = true;
item.Extension ="folder";
listFolder.Add(item);
}
docList = CreatXmllist(listFolder);
return docList
public xml (string path, List<l> one)
{
List< T > tt = new List< T >();
List< T > SessionList = new List< T >();
string[] files = Directory.GetFiles(HttpContext.Current.Request.PhysicalApplicationPath + path);
foreach (string file in files)
{
FileSystemItem item = new FileSystemItem();
FileInfo i = new FileInfo(file);
string a = i.LastWriteTime.ToString();
var thumbnails = from a in b where a.Name == fi.Name select t;
if (fi.Name !="a")
if (t.Count() == 0)
{
r session r = new r();
r.aName = fi.aName;
SessionList.Add(r);
fi.Exists;
}
else
t.Add((T)t.First());
}
FileInfo file = new FileInfo(source);
file.MoveTo(destination);
// execute more code
file.MoveTo(destination2)这就是我获取文件夹列表的方式，然后将其返回到 xml。然后在文件夹中，当我单击它时我会得到文件
现在获取图像：这是代码
File.Move(source,Destination);
File.Delete(source);
foreach (string folder in folder)
{
FileSystemItem item = new FileSystemItem();
DirectoryInfo di = new DirectoryInfo(folder);
item.Name = di.Name;
item.FullName = di.FullName;
item.Path = path +"\" + item.Name;
item.CreatedDate = di.CreationTime;
item.IsFolder = true;
item.Extension ="folder";
listFolder.Add(item);
}
docList = CreatXmllist(listFolder);
return docList
public xml (string path, List<l> one)
{
List< T > tt = new List< T >();
List< T > SessionList = new List< T >();
string[] files = Directory.GetFiles(HttpContext.Current.Request.PhysicalApplicationPath + path);
foreach (string file in files)
{
FileSystemItem item = new FileSystemItem();
FileInfo i = new FileInfo(file);
string a = i.LastWriteTime.ToString();
var thumbnails = from a in b where a.Name == fi.Name select t;
if (fi.Name !="a")
if (t.Count() == 0)
{
r session r = new r();
r.aName = fi.aName;
SessionList.Add(r);
fi.Exists;
}
else
t.Add((T)t.First());
}
FileInfo file = new FileInfo(source);
file.MoveTo(destination);
// execute more code
file.MoveTo(destination2)你不需要在重命名过程中调用 File.Delete，如果你做了一个副本，你会需要它。
创建一个 FileInfo 实例，您可以在其中多次重命名它。
File.Move(source,Destination);
File.Delete(source);
foreach (string folder in folder)
{
FileSystemItem item = new FileSystemItem();
DirectoryInfo di = new DirectoryInfo(folder);
item.Name = di.Name;
item.FullName = di.FullName;
item.Path = path +"\" + item.Name;
item.CreatedDate = di.CreationTime;
item.IsFolder = true;
item.Extension ="folder";
listFolder.Add(item);
}
docList = CreatXmllist(listFolder);
return docList
public xml (string path, List<l> one)
{
List< T > tt = new List< T >();
List< T > SessionList = new List< T >();
string[] files = Directory.GetFiles(HttpContext.Current.Request.PhysicalApplicationPath + path);
foreach (string file in files)
{
FileSystemItem item = new FileSystemItem();
FileInfo i = new FileInfo(file);
string a = i.LastWriteTime.ToString();
var thumbnails = from a in b where a.Name == fi.Name select t;
if (fi.Name !="a")
if (t.Count() == 0)
{
r session r = new r();
r.aName = fi.aName;
SessionList.Add(r);
fi.Exists;
}
else
t.Add((T)t.First());
}
FileInfo file = new FileInfo(source);
file.MoveTo(destination);
// execute more code
file.MoveTo(destination2)尝试使用 FileShare 枚举器。然后尝试用 monesharing 打开一个文件，关闭句柄，如果没有异常就可以移动文件了。

它包含读取、写入等方法。
