如何将文件从一个路径移动到另一个路径？ [英] how to move file from one path to another ?

问题描述

这是我写的代码，但它不起作用。请看看

  string  destination = Path.Combine（
 DataFeed.CaremarkInbound.Locations.CaremarkInboundArchive， new  DirectoryInfo（
 file.CurrentFilePath）.Name）; 
 Directory.Move（file.CurrentFilePath，destination）; 

获得例外

当该文件已存在时，无法创建文件 

提前谢谢

解决方案

错误是不言自明的？在您进行移动之前，请使用File.Exists查看目标文件是否存在，以及是否删除它

here is the code i have written but it is not working. please have a look

string destination = Path.Combine(
                       DataFeed.CaremarkInbound.Locations.CaremarkInboundArchive, new DirectoryInfo(
                           file.CurrentFilePath).Name);
                   Directory.Move(file.CurrentFilePath, destination);

getting the exception as

Cannot create a file when that file already exists

Thanks in advance

解决方案

The error is self-explanatory? Before you do the move use File.Exists to see if the destination file exists, and if it does delete it
