How to get files in the subfolders too from directory

问题

Hi I have to get files from a specified path in the directory. This is the method I wrote but I didn't get the files from the subfolders.

Private void getfiles(){
Directoryinfo info = new Directoryinfo(configurationmanager.appsettings["Targetroot"].tostring ());
if (info.exists){
     Gvfiles.datasource = info.GetFiles();
     Gvfiles.databind();
   }
}

回答1:

You will want to include the SearchOption.AllDirectories.

Example:

info.GetFiles("*", SearchOption.AllDirectories);

Reference: http://msdn.microsoft.com/en-us/library/ms143327(v=vs.80).aspx

And: http://msdn.microsoft.com/en-us/library/ms143448(v=vs.80).aspx

This returns an array of the (immediate) subdirectories:

System.IO.DirectoryInfo ParentDirectory = new System.IO.DirectoryInfo(ParentPath);
System.IO.DirectoryInfo[] DirectoryArr = ParentDirectory.GetDirectories();

I'm sure you can find a way to adapt it to your likings.

DirectoryInfo info = new   DrectoryInfo(configurationmanager.appsettings["Targetroot"].tostring ());
//FileInfo[] _files = info.GetFiles("You could set a search pattern");
//FileInfo[] _files = info.GetFiles("*.aspx");
FileInfo[] _files = info.GetFiles();
Gvfiles.datasource = _files;
Gvfiles.databind();

or:

DirectoryInfo info = new DirectoryInfo(Server.MapPath("/"));
DirectoryInfo[] _info = info.GetDirectories();
for (int i = 0; i < _info.Length; i++)
{
FileInfo[] files = _info[i].GetFiles("search pattern");
Gvfiles.datasource = files;
Gvfiles.databind();
}

private List<String> DirSearch(string sDir)
{
List<String> files = new List<String>();
try
{
    foreach (string f in Directory.GetFiles(sDir))
    {
        files.Add(f);
    }
    foreach (string d in Directory.GetDirectories(sDir))
    {
        files.AddRange(DirSearch(d));
    }
}
catch (System.Exception excpt)
{
    MessageBox.Show(excpt.Message);
}

    return files;
}
