I have this code:
private void SearchForDoc()
{
try
{
outputtext = @"c:\temp\outputtxt";
outputphotos = @"c:\temp\outputphotos";
temptxt = @"c:\temp\txtfiles";
tempphotos = @"c:\temp\photosfiles";
if (!Directory.Exists(temptxt))
{
Directory.CreateDirectory(temptxt);
}
if (!Directory.Exists(tempphotos))
{
Directory.CreateDirectory(tempphotos);
}
if (!Directory.Exists(outputtext))
{
Directory.CreateDirectory(outputtext);
}
if (!Directory.Exists(outputphotos))
{
Directory.CreateDirectory(outputphotos);
}
t = Environment.GetEnvironmentVariable(Environment.GetFolderPath(Environment.SpecialFolder.Personal));
ApplyAllFiles(t,ProcessFile(t);
for (int i = 0; i < textfiles.Length; i++)
{
FileInfo fi = new FileInfo((textfiles[i]));
DirectoryInfo d = new DirectoryInfo(temptxt);
long dirSize = DirSize(d);
if ((dirSize + fi.Length) <= 8388608)
fi.CopyTo(temptxt + "\\" + fi.Name, true);
else
break;
}
Then in after this i have two methods:
static void ProcessFile(string path) {/* ... */}
static void ApplyAllFiles(string folder, Action<string> fileAction)
{
foreach (string file in Directory.GetFiles(folder))
{
fileAction(file);
}
foreach (string subDir in Directory.GetDirectories(folder))
{
try
{
ApplyAllFiles(subDir, fileAction);
}
catch
{
// swallow, log, whatever
}
}
}
Using this two methods in my method should get all text files from the document directory and all its subdirectories.
In my method i did:
ApplyAllFiles(t,ProcessFile(t);
But that is wrong way to use it. How can i use the methods ?
由于ProcessFile
方法已经具有与Action<string>
相同的签名,因此您只需指定方法名称即可:
ApplyAllFiles(t, ProcessFile);
