Console.ForegroundColor = ConsoleColor.Cyan;
Console.WriteLine(successfull);
Console.ForegroundColor = ConsoleColor.Green;

files1.Add("file3.exe");
files1.Add("file4.exe");
files1.Add("file5.exe");
}
}
Error arrive when I try to delete the thirth, please help.

Answer 1

What about this:
for(int i = 0; i < ExampleList.Count; i++)
{
if (enter == "del" + space + FIles.files1[i] && admin == true && connected == true && cdMain == true )
{
FIles.files1.RemoveAt(i);
Console.WriteLine("");
FIles.files1.ForEach(Console.WriteLine);
Console.ForegroundColor = ConsoleColor.Cyan;
Console.WriteLine(successfull);
Console.ForegroundColor = ConsoleColor.Green;
}
}
The problem with your code is that the size of your list is changing each time you call RemoveAt. After two calls your list has a size of 3 and FIles.files1[3] is out of range.
