c#复制包含子目录文件夹代码

c#没有复制目录的代码，需要通过递归实现复制目录：

需要引用System.IO命名空间，实现代码如下：

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);

上面的方法将把c:\temp\index目录下的所有子目录和文件复制到 c:\temp\newindex目录下。
