c#中如何使用仅仅有函数的DLL

[yilinpang]

如果该DLL中仅仅有函数，不能在工程中添加引用来使用，如何使用该种DLL呢

[-_-中英文数字]

using System.Runtime.InteropServices;

[DllImport("your.dll")]
static extern /* your function signature here */;

只能使用楼上说的了,如果不想找麻烦的话.

给你个播放声音的类，参考一下
public class sndPlay
{
//声音动态连接库声明
[DllImport("winmm.dll", EntryPoint="PlaySound")]
public static extern bool PlaySound(ref Byte snd, IntPtr hmod, uint fdwSound);

[DllImport("winmm.dll", EntryPoint="PlaySound")]
public static extern int PlaySound(string lpszName,int hModule,int dwFlags);

public enum PlayingFlags :uint
{
SND_SYNC = 0x00,
SND_ASYNC = 0x01,
SND_NODEFAULT = 0x02,
SND_MEMORY = 0x04,
SND_ALIAS = 0x010000,
SND_FILENAME = 0x020000,
SND_RESOURCE = 0x040004,
SND_ALIAS_ID = 0x0110000,
SND_ALIAS_START = 0,
SND_LOOP = 0x08,
SND_NOSTOP = 0x010,
SND_VALID = 0x01F,
SND_NOWAIT = 0x02000,
SND_PURGE = 0x40
}
}
