Hi, I am using Downloadfile() method of System.Net.Webclient class to download file present in server to local directory. I want to know whether it will overwrite the existing file or not. My Observation: Time stamp in the new file is shown as old file. Is there any method to download file with overwrite option other than My.Computer.Network.Downloadfile()? Thanks in advance, Vijay

推荐答案

如社区内容中所述，它将覆盖文件(如果存在). msdn.microsoft/en-us/library/ez801hhe (v = VS.80).aspx [ ^ ] 谈论时间戳，它将具有相同的Created戳.您应该检查Modified印章. As it says in Community Content, it will overwrite the file if it exists. msdn.microsoft/en-us/library/ez801hhe(v=VS.80).aspx[^] Talking about time stamp, it will have same Created stamp. You should check Modified stamp.
