C# Problem foreach

hello, can some take a look at this, it doesnt work as it should be

string[] fileid = { "1.txt", "2.txt", "3.txt"};
foreach (string fileidb in fileid)
{
string[] path = Directory.GetFiles(@"temp", fileidb, SearchOption.AllDirectories);
try
{
if (File.Exists(path[0]))
{
foreach (string fileidc in fileid)
{
Console.WriteLine("{0} ", fileidc);
}
}
}
catch (Exception)
{
}

the console output should be

1.txt
2.txt
3.txt

but it is this

1.txt
2.txt
3.txt
1.txt
2.txt
3.txt
1.txt
2.txt
3.txt

Instead of:

if (File.Exists(path[0]))
{
foreach (string fileidc in fileid)
{
Console.WriteLine("{0} ", fileidc);
}
}

Do you mean:

if (File.Exists(path[0]))
{
Console.WriteLine("{0} ", fileidb);
}

Also, you can probably omit the File.Exists check. If Directory.GetFiles found it, the file exists (unless it got deleted after Directory.GetFiles found it).
