文件或文件夹重命名为小写在 C# 中使用 DirectoryInfo/FileInfo.MoveTo()
我有一个程序可以将文件或文件夹重命名为小写名称。我写了这段代码：
private void Replace(string FolderLocation, string lastText, string NewText)
{
if (lastText == "")
{
lastText = " ";
}
if (NewText == "")
{
NewText = " ";
}
DirectoryInfo i = new DirectoryInfo(FolderLocation);
string NewName = "";
if (checkBox2.Checked)
{
if (i.Parent.FullName[i.Parent.FullName.Length - 1].ToString() != "\\") //For parents like E:/
{
NewName = i.Parent.FullName + "\\" + i.Name.Replace(lastText, NewText);
}
else
{
NewName = i.Parent.FullName + i.Name.Replace(lastText, NewText);
}
NewName = NewName.ToLower();
if (NewName != i.FullName)
{
i.MoveTo(NewName);
}
foreach (DirectoryInfo sd in i.GetDirectories())
{
Replace(sd.FullName, lastText, NewText);
}
}
if (checkBox1.Checked)
{
foreach (FileInfo fi in i.GetFiles())
{
NewName = fi.Directory + "\\" + fi.Name.Replace(lastText, NewText);
NewName = NewName.ToLower();
if (NewName != fi.FullName)
{
fi.MoveTo(NewName);
}
}
}
}
但我得到以下异常：
“源路径和目标路径必须不同。”
我该如何解决这个问题？
I have a program that renames files or folders to lower case names. I have written this code:
private void Replace(string FolderLocation, string lastText, string NewText)
{
if (lastText == "")
{
lastText = " ";
}
if (NewText == "")
{
NewText = " ";
}
DirectoryInfo i = new DirectoryInfo(FolderLocation);
string NewName = "";
if (checkBox2.Checked)
{
if (i.Parent.FullName[i.Parent.FullName.Length - 1].ToString() != "\\") //For parents like E:/
{
NewName = i.Parent.FullName + "\\" + i.Name.Replace(lastText, NewText);
}
else
{
NewName = i.Parent.FullName + i.Name.Replace(lastText, NewText);
}
NewName = NewName.ToLower();
if (NewName != i.FullName)
{
i.MoveTo(NewName);
}
foreach (DirectoryInfo sd in i.GetDirectories())
{
Replace(sd.FullName, lastText, NewText);
}
}
if (checkBox1.Checked)
{
foreach (FileInfo fi in i.GetFiles())
{
NewName = fi.Directory + "\\" + fi.Name.Replace(lastText, NewText);
NewName = NewName.ToLower();
if (NewName != fi.FullName)
{
fi.MoveTo(NewName);
}
}
}
}
But I get the following exception:
"Source and destination path must be different."
How can I solve this issue?

由于 Windows 不区分大小写，因此就文件名而言，您需要将文件重命名为临时名称，然后用小写字符重命名回来。
Since Windows is case insensitive, as far as file names are concerned, you will need to rename the file to a temporary name then rename back with lowercase characters.
尽管 Windows 文件系统存储名称区分大小写，但它们在名称比较时不区分大小写，因此您的重命名操作将不起作用...
如果您确实需要/想要这样做，则需要首先将文件/目录临时重命名为不同的名称并且是唯一的，然后将其重命名为您想要的“小写名称”。
有关参考，请参阅 http://msdn.microsoft。 com/en-us/library/ee681827%28v=vs.85%29.aspx 和 http://support.microsoft.com/kb/100108/en-us 。
如果您需要 NTFS 区分大小写，可以将
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\下的双字ObCaseInsensitive设置为 0（不推荐！） 。如果您正在处理 NFS，请参阅 http://technet .microsoft.com/en-us/library/cc783185%28WS.10%29.aspx。
Although Windows Filesystems store names case-senstivie they behave case-insensitive on name comparison thus your renaming operation won't work...
IF you really need/want to do that you will need to first rename temporarily the file/directory to something different and unique, then rename it "back" to the "lower case name" you want.
For reference see http://msdn.microsoft.com/en-us/library/ee681827%28v=vs.85%29.aspx and http://support.microsoft.com/kb/100108/en-us .
IF you need NTFS to be case-sensitive you can set the dword
ObCaseInsensitiveunderHKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\to 0 (NOT RECOMMENDED!).IF you are dealing with NFS then see http://technet.microsoft.com/en-us/library/cc783185%28WS.10%29.aspx .
这有效：
This works:
不幸的是，这是一个 Windows 问题，因为正如 Oded 在评论中提到的那样，它不区分大小写。您所要做的就是将该文件夹重命名两次。通过将文件夹移动到新的临时名称，然后返回到原始名称的小写字母。
Unfortunately this is a windows issue as it is case insensitive as Oded mentions in the comments. What you would have to do is to rename the folder twice. By moving the folder to a new temporary name then back to the lowercase of the original name.
