Jak używać [DllImport ( "" )] w C#?
Znalazłem wiele pytań na ten temat, ale nikt nie wyjaśnia, jak mogę tego użyć.
Mam to:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Windows.Forms;
using Microsoft.FSharp.Linq.RuntimeHelpers;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.IO;
public class WindowHandling
{
public void ActivateTargetApplication(string processName, List<string> barcodesList)
{
[DllImport("User32.dll")]
public static extern int SetForegroundWindow(IntPtr point);
Process p = Process.Start("notepad++.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
IntPtr processFoundWindow = p.MainWindowHandle;
}
}
Czy ktoś może mi pomóc zrozumieć, dlaczego daje mi błąd na linii DllImport
i na linii public static
?

Nie Można zadeklarować lokalnej metody extern
wewnątrz metody, ani żadnej innej metody z atrybutem. Przenieś import DLL do klasy:
using System.Runtime.InteropServices;
public class WindowHandling
{
[DllImport("User32.dll")]
public static extern int SetForegroundWindow(IntPtr point);
public void ActivateTargetApplication(string processName, List<string> barcodesList)
{
Process p = Process.Start("notepad++.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
IntPtr processFoundWindow = p.MainWindowHandle;
}
}
