Method listDuplicates() error - c#-3.0

Question

Can somebody help me with this problem here. I'm a newbie . I'm trying to find file duplicates or files with the same content in a directory and write texfile to display duplicates but now it says input string was not in a correct format
public static List<FileInfo> files = new List<FileInfo>();
public static void ListDrive(string drive)
{
try
{
DirectoryInfo di = new DirectoryInfo(drive);
foreach (FileInfo fi in di.GetFiles())
{
files.Add(fi);
}
}
catch (UnauthorizedAccessException)
{ }
}
//Find duplicates
public static void ListDuplicates()
{
var duplicatedFiles = files.GroupBy(x => new { x.Length }).Where(t => t.Count() > 1).ToList();
Console.WriteLine("Total items: {0}", files.Count);
Console.WriteLine("Probably duplicates {0} ", duplicatedFiles.Count());
StreamWriter duplicatesFoundLog = new StreamWriter("log.txt");
foreach (var filter in duplicatedFiles)
{
duplicatesFoundLog.WriteLine("Probably duplicated item: Name: { 0}, Length: { 1}",
filter.Key.Length);
var items = files.Where(x => x.Length == filter.Key.Length).ToList();
int c = 1;
foreach (var suspected in items)
{
duplicatesFoundLog.WriteLine("{3},{ 0}- { 1}, Creation date { 2}",
suspected.Name, suspected.FullName, suspected.CreationTime, c);
c++;
}
duplicatesFoundLog.WriteLine();
}
duplicatesFoundLog.Flush();
duplicatesFoundLog.Close();
}
Here is my client method that invokes the two methods
try
{
Console.WriteLine("Enter the path");
string path = Console.ReadLine();
ListDrive(path);
ListDuplicates();
Console.ReadLine();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
Console.ReadLine();
}
Your help will be high appreciated...

Answer 1

Please eliminate the space, for example change { 0} to {0}. If you do this for all locations the error should go away.
If you want spaces, make the code "{3}, {0}- {1}, Creation date {2}". i.e. Add the space before the opening {, not after. The format items need have no space after the first opening brace to be interpreted as a formatting item correctly.
