c#如何给文件或文件夹重命名 用file.move 原形： public static void Move ( string sourceFileName, string destFileName ) 参数 sourceFileName 要移动的文件的名称。 destFileName 文件的新路径。
using System; using System.IO; class Test { public static void Main() { string path = @"c:\temp\MyTest.txt"; string path2 = @"c:\temp2\MyTest.txt"; try { if (!File.Exists(path)) { // This statement ensures that the file is created, // but the handle is not kept. using (FileStream fs = File.Create(path)) {} } // Ensure that the target does not exist. if (File.Exists(path2)) File.Delete(path2); // Move the file. File.Move(path, path2); Console.WriteLine("{0} was moved to {1}.", path, path2); // See if the original exists now. if (File.Exists(path)) { Console.WriteLine("The original file still exists, which is unexpected."); } else { Console.WriteLine("The original file no longer exists, which is expected."); } } catch (Exception e) { Console.WriteLine("The process failed: {0}", e.ToString()); } } }
using System; using System.IO; class Test { public static void Main() { string path = @"c:\temp\MyTest.txt"; string path2 = @"c:\temp2\MyTest.txt"; try { if (!File.Exists(path)) { // This statement ensures that the file is created, // but the handle is not kept. using (FileStream fs = File.Create(path)) {} } // Ensure that the target does not exist. if (File.Exists(path2)) File.Delete(path2); // Move the file.
