How to make the code not delete a specific file I want among the .exe I get. Example: I want it not to delete "test.exe", but still keep erasing everything else.
Follow the code:
string[] arquivos = Directory.GetFiles(@"C:\temp\ae", "*.exe", SearchOption.TopDirectoryOnly);
foreach (string arquivo in arquivos)
{
//nome = Path.GetFileName(arquivo);
File.Delete(arquivo);
}
foreach (var arquivo in Directory.GetFiles(@"C:\temp\ae", "*.exe", SearchOption.TopDirectoryOnly) {
if (Path.GetFileName(arquivo) != "teste.exe") File.Delete(arquivo);
}
If you prefer you can do with LINQ, I would, because it is more performative in this case. Doing right despite having a bit of overhead by the LINQ infrastructure it does just a loop . In Barbetta's answer he does 2 loops , one to get the files and another to filter. The Enumerate does not execute loop any.
foreach (var arquivo in Directory.EnumerateFiles(@"C:\temp\ae", "*.exe", SearchOption.TopDirectoryOnly).Where(f => Path.GetFileName(f) != "teste.exe") File.Delete(arquivo);
You can use a conditional within the foreach itself, like this:
string[] arquivos = Directory.GetFiles(@"C:\temp\ae", "*.exe", SearchOption.TopDirectoryOnly);
foreach (string arquivo in arquivos)
{
var nome = Path.GetFileName(arquivo);
if (nome != "teste.exe")
File.Delete(arquivo);
}
Follow one more option using linq
string[] arquivos = Directory.GetFiles(@"C:\temp\ae", "*.exe", SearchOption.TopDirectoryOnly).Where(p => p != "teste.exe").ToArray();
foreach (string arquivo in arquivos)
File.Delete(arquivo);
