我有一个解决方案,它有一个带有函数的 c++ dll 项目(MsgHook.cpp):-
BOOL f_closeSEB()
{
logg(fp, "\n\n");
//TerminateProcess(hPiProcess->hProcess,0);
SendMessage(hWndCaller,WM_DESTROY,NULL,NULL);
logg(fp, " SEB exit sequence, destroy window\n");
//logg(fp, "Leave LLKeyboardHook() and return -1\n\n");
return -1;
}
我正在尝试通过以下方式从我的 c# Web 服务项目中调用此函数:-
using System.Runtime.InteropServices;
namespace closeSEB
{
partial class closeSEBService
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
public enum commands
{
CloseIt=255
}
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}
[DllImport("MsgHook.dll", SetLastError = true)]
public static extern void runRTS(string serviceName);
protected override void OnCustomCommand(int command)
{
base.OnCustomCommand(command);
if (command == (int)commands.CloseIt)
{
//Code to call msghook closeSEB function
runRTS("closeSEBService");
f_closeSEB();
}
}
#region Component Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
//
// closeSEBService
//
this.ServiceName = "Service1";
}
#endregion
}
}
但是在编译器中,我收到一个错误,即名称 f_closeSEB 在当前上下文中没有退出。这不是通过 C# 调用 DLL 文件中定义的函数的正确方法吗?
