c#沒有復制目錄的代碼，需要通過遞歸實現復制目錄：
需要引用System.IO命名空間，實現代碼如下：
private static bool CopyDirectory(string SourcePath, string DestinationPath, bool overwriteexisting) { bool ret = false; try { SourcePath = SourcePath.EndsWith(@"\") ? SourcePath : SourcePath + @"\"; DestinationPath = DestinationPath.EndsWith(@"\") ? DestinationPath : DestinationPath + @"\"; if (Directory.Exists(SourcePath)) { if (Directory.Exists(DestinationPath) == false) Directory.CreateDirectory(DestinationPath); foreach (string fls in Directory.GetFiles(SourcePath)) { FileInfo flinfo = new FileInfo(fls); flinfo.CopyTo(DestinationPath + flinfo.Name, overwriteexisting); } foreach (string drs in Directory.GetDirectories(SourcePath)) { DirectoryInfo drinfo = new DirectoryInfo(drs); if (CopyDirectory(drs, DestinationPath + drinfo.Name, overwriteexisting) == false) ret = false; } } ret = true; } catch (Exception ex) { ret = false; } return ret; }
使用方法：
bool copy = CopyDirectory("c:\\temp\\index\\", "c:\\temp\\newindex\\", true);
上面的方法將把c:\temp\index目錄下的所有子目錄和文件復制到 c:\temp\newindex目錄下。
