,您可以利用並行LINQ的和做如下
int count = 0;
string[] files = null;
try
{
files = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);
}
catch (UnauthorizedAccessException e)
{
Console.WriteLine("You do not have permission to access one or more folders in this directory tree.");
return;
}
catch (FileNotFoundException)
{
Console.WriteLine("The specified directory {0} was not found.", path);
}
var fileContents = from file in files.AsParallel()
let extension = Path.GetExtension(file)
where extension == ".xml"
let text = File.ReadAllText(file)
select new FileResult { Text = text , FileName = file }; //Or ReadAllBytes, ReadAllLines, etc.
try
{
foreach (var item in fileContents)
{
Console.WriteLine(Path.GetFileName(item.FileName) + ":" + item.Text.Length);
count++;
}
}
catch (AggregateException ae)
{
ae.Handle((ex) =>
{
if (ex is UnauthorizedAccessException)
{
Console.WriteLine(ex.Message);
return true;
}
return false;
});
}
