问题描述

static class Class    
{
    public static void methodRequiringStuffFromKernel32()
    {
        // code here...
    }
} 

在哪里我把函数[DllImport(Kernel32中.DLL)] 在这里?

推荐答案

您把它放在你从导入方法KERNEL32.DLL。

You put it on the method you're importing from Kernel32.dll.

例如,

static class Class    
{
    [DllImport("Kernel32.dll")]
    static extern Boolean Beep(UInt32 frequency, UInt32 duration);

    public static void methodRequiringStuffFromKernel32()
    {
        // code here...
        Beep(...);
    }
}






从@ :请注意,类应命名为 NativeMethods SafeNativeMethods UnsafeNativeMethods 。请参见,获取更多详情。


From @dtb: Note that the class should be named NativeMethods, SafeNativeMethods or UnsafeNativeMethods. See Naming Convention for Unmanaged Code Methods for more details.


  • NativeMethods - 这个类不禁止堆散步对于非托管代码的权限。 (System.Security.SuppressUnmanagedCodeSecurityAttribute不能应用于此类。)这个类是可以在任何地方使用,因为堆栈步将要执行的方法。

SafeNativeMethods - 这个类抑制栈走对于非托管代码的权限。 (System.Security.SuppressUnmanagedCodeSecurityAttribute应用于此类。)这个类是安全的人来调用方法。这些方法的调用者不需要进行全面的安全审查,以确保使用是安全的,因为这些方法都是无害因任何调用

SafeNativeMethods - This class suppresses stack walks for unmanaged code permission. (System.Security.SuppressUnmanagedCodeSecurityAttribute is applied to this class.) This class is for methods that are safe for anyone to call. Callers of these methods are not required to perform a full security review to make sure that the usage is secure because the methods are harmless for any caller.

UnsafeNativeMethods - 这个类可以抑制栈走对于非托管代码的权限。 (System.Security.SuppressUnmanagedCodeSecurityAttribute应用于此类。)这个类是有潜在危险的方法。这些方法的调用方必须进行全面的安全审查,以确保使用是安全的,因为没有堆栈步行将被执行。

UnsafeNativeMethods - This class suppresses stack walks for unmanaged code permission. (System.Security.SuppressUnmanagedCodeSecurityAttribute is applied to this class.) This class is for methods that are potentially dangerous. Any caller of these methods must perform a full security review to make sure that the usage is secure because no stack walk will be performed.
