asp.net中C#檔案和檔案夾的複製、刪除、移動實現程式

代碼如下

複製代碼

public class SimpleFileCopy{ static void Main()      { string fileName = "test.txt";  string sourcePath = @"C:UsersPublicTestFolder"; string targetPath = @"C:UsersPublicTestFolderSubDir";  string sourceFile = System.IO.Path.Combine(sourcePath, fileName);  string destFile = System.IO.Path.Combine(targetPath, fileName); if (!System.IO.Directory.Exists(targetPath))          {              System.IO.Directory.CreateDirectory(targetPath);          }   System.IO.File.Copy(sourceFile, destFile, true); if (System.IO.Directory.Exists(sourcePath)){  string[] files = System.IO.Directory.GetFiles(sourcePath);   foreach (string s in files) {  fileName = System.IO.Path.GetFileName(s);                  destFile = System.IO.Path.Combine(targetPath, fileName);                  System.IO.File.Copy(s, destFile, true);              }          } else {              Console.WriteLine("Source path does not exist!");          }  Console.WriteLine("Press any key to exit.");          Console.ReadKey();      }  }

下面的樣本示範如何移動檔案和目錄。

代碼如下	複製代碼
public class SimpleFileMove {  static void Main()      {  string sourceFile = @"C:UsersPublicpublictest.txt";  string destinationFile = @"C:UsersPublicprivatetest.txt";  System.IO.File.Move(sourceFile, destinationFile);  System.IO.Directory.Move(@"C:UsersPublicpublictest", @"C:UsersPublicprivate");      }  }

下面的樣本示範如何刪除檔案和目錄。

代碼如下
