如何在C＃中将文件从一个路径移动到另一路径

Question

In my application I could have three paths

1. \\Shared\\1.txt
2. \\Shared\\
3. \\Shared\\*.txt

This file paths will come in variable.

Now How can I check if path has single file or multiple or it has wildcard ? & then move them to another path.

Answer 1

Well, since neither * nor ? can be in the path: they are in

  Char[] forbidden = Path.GetInvalidPathChars();

so you can just look for them

  String path = @"C:\MyData\Shared\*.txt";
  ...
  Boolean isWildCard = path.ContainsAny('?', '*');

As for File/Directory

  Boolean isFile;

  if (File.Exists(path)) 
    isFile = true; // file already exists
  else if (Directory.Exists(path)) 
    isFile = false; // directory already exists
  else if (String.Equals(Path.GetExtension(path), ".txt", StringComparison.InvariantCultureIgnoreCase))
    isFile = true; // has txt extension, let it be a file
  else
    isFile = false;

However it seems that you have no need to have any branches (isWildCard, isFile) and just move files:

  String path = @"C:\MyData\Shared\*.txt";
  ...
  String sourceDirectory = Path.GetDirectoryName(path);  
  String destination = @"C:\Destination";

  Directory.GetFiles(sourceDirectory, "*.txt")
           .ForEach(file => File.Move(file, Path.Combine(destination, Path.GetFileName(file))));
