我如何重命名一个文件使用c# ?
当前回答
添加:
namespace System.IO
{
public static class ExtendedMethod
{
public static void Rename(this FileInfo fileInfo, string newName)
{
fileInfo.MoveTo(fileInfo.Directory.FullName + "\\" + newName);
}
}
}
然后……
FileInfo file = new FileInfo("c:\test.txt");
file.Rename("test2.txt");

看一下System.IO.File。移动,“移动”文件到一个新名称。
System.IO.File.Move("oldfilename", "newfilename");
First solution Avoid System.IO.File.Move solutions posted here (marked answer included). It fails over networks. However, copy/delete pattern works locally and over networks. Follow one of the move solutions, but replace it with Copy instead. Then use File.Delete to delete the original file. You can create a Rename method to simplify it. Ease of use Use the VB assembly in C#. Add reference to Microsoft.VisualBasic Then to rename the file: Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(myfile, newName); Both are strings. Note that myfile has the full path. newName does not. For example: a = "C:\whatever\a.txt"; b = "b.txt"; Microsoft.VisualBasic.FileIO.FileSystem.RenameFile(a, b); The C:\whatever\ folder will now contain b.txt.
public void RenameFile(string filePath, string newName)
{
FileInfo fileInfo = new FileInfo(filePath);
fileInfo.MoveTo(fileInfo.Directory.FullName + "\\" + newName);
}
你可以将它复制为一个新文件,然后使用System.IO.File类删除旧文件:
if (File.Exists(oldName))
{
File.Copy(oldName, newName, true);
File.Delete(oldName);
}
System.IO.File.Move(oldNameFullPath, newNameFullPath);
