C#获取指定目录下某种格式文件集并备份到指定文件夹

1.获取文件的路径和移动到文件夹信息

string fileName = ""; string sourceFile = @"F:\Test文件夹\CSV"; string bakFilePath = @"F:\Test文件夹\CSV\bak";

2.获取文件夹下文件信息,并移动到Bak操作。

//匹配.csv的文件路径地址集合 string[] FullfillfilesList = Directory.GetFiles(sourceFile, "*.csv", 0); if (FullfillfilesList.Length > 0) { foreach (string Fullfillfiles in FullfillfilesList) { //每一个文件名称 fileName = Fullfillfiles.Substring(Fullfillfiles.LastIndexOf('\\') + 1); //移动到Bak文件夹 ExecutionResult res = MoveFileToBak(sourceFile + "/" + fileName, bakFilePath, fileName); } }

3.文件移动到Bak方法

public static ExecutionResult MoveFileToBak(string sourceFile, string bakFilePath, string bakFileName) { ExecutionResult result; FileInfo tempFileInfo; FileInfo tempBakFileInfo; DirectoryInfo tempDirectoryInfo; result = new ExecutionResult(); tempFileInfo = new FileInfo(sourceFile); tempDirectoryInfo = new DirectoryInfo(bakFilePath); tempBakFileInfo = new FileInfo(bakFilePath + "\\" + bakFileName); try { if (!tempDirectoryInfo.Exists) tempDirectoryInfo.Create(); if (tempBakFileInfo.Exists) tempBakFileInfo.Delete(); //move file to bak tempFileInfo.MoveTo(bakFilePath + "\\" + bakFileName); result.Status = true; result.Message = "Move File To Bak OK"; result.Anything = "SEND OK"; } catch (Exception ex) { result.Status = false; result.Anything = "SEND Fail"; result.Message = ex.Message; } return result; }
