i am trying to get a list of files into an array or list from multiple directories
currently i am doing:
tempbatchaddresses = Directory.GetFiles(@"c:\", "*.log"); but i also need tempbatchaddresses += Directory.GetFiles(@"d:\", "*.log");
and a third one as well. i need to add the file locations of files from 3 different directories.
how do i do this?
tempBatchAddresses = Directory.GetFiles(@"c:\", "*.log").ToList(); tempBatchAddresses.AddRange(Directory.GetFiles(@"d:\", "*.log").ToList()); tempBatchAddresses.AddRange(Directory.GetFiles("some dir", "some pattern").ToList()); and so on ..
Try something like this:
List<string> myFiles = new List<string>(); myFiles.AddRange(Directory.GetFiles(@"c:\", "*.log")); ...etc... foreach (string file in myFiles) { //do whatever you want } There are a myriad number of similar ways to tackle the problem. Here's one.
static void Main() { IEnumerable<string> files = GetFiles("*.log", @"C:\", @"D:\", @"E:\"); } static IEnumerable<string> GetFiles(string searchPattern, params string[] directories) { foreach (string directory in directories) { foreach (string file in Directory.GetFiles(directory, searchPattern)) yield return file; } }
