如何检查服务器上是否存在pdf文件？

Question

Is it possible to check if any file with .pdf extension exists on server? I know i can use: File.Exists(Server.MapPath("/somepath"))); but this is when I'm looking for specific file. Is it possible to just look for the file extension?

Answer 1

Yes you can find all the files with certain extension, here is a sample code:

string[] files = System.IO.Directory.GetFiles(Server.MapPath("/somepath"), "*.txt");

Hope this helps.

Answer 2

Currently i'm working with this Method:

public IEnumerable<FileInfo> FindFilesInDirectory(string dirPath)
{
    return Directory.Exists(dirPath)
               ? Directory.GetFiles(dirPath, "*.pdf", SearchOption.AllDirectories)
                          .ToList()
                          .ConvertAll(x => new FileInfo(x))
               : null;
}

Not sure if it works with Server.MapPath("/somepath")
