C# Signature:
[DllImport("kernel32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool DeleteFile(string lpFileName);
[DllImport("kernel32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool DeleteFileA([MarshalAs(UnmanagedType.LPStr)]string lpFileName);
[DllImport("kernel32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool DeleteFileW([MarshalAs(UnmanagedType.LPWStr)]string lpFileName);
User-Defined Types:
None.
Notes:
I couldn't get DeleteFile to work on Windows XP - I always get a return code of 2 (File not found). I used DeleteFileW instead.
Tips & Tricks:
Please add some!
Sample Code:
String filePath = @"C:\Data\MyFile.txt";
bool deleted = DeleteFileW(filePath);
if (!deleted)
{
int lastError = Marshal.GetLastWin32Error();
Console.WriteLine("Failed to delete '{1}': error={0}", lastError, filePath);
}
Alternative Managed API:
System.IO.File:
public static void Delete(string path);
