我想在点击按扭后调用C++编写的ProWav里面的PlayWave程序来播放一个音乐，地址存放在FileName里面。各位看看我的程序 有没有什么问题啊？

[DllImport("ProWav.dll", EntryPoint = "PlayWave", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]

public static extern string pro(string FileName);

private void 播放_Click(object sender, EventArgs e)
{
这里怎么写才能把路径传递到 PlayWave里面去啊...PlayWave里面定义了个路径名叫FileName...
}
应该怎么改啊？？？？？

[DllImport("ProWav.dll", EntryPoint = "PlayWave", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]

public static extern string pro(string FileName);

private void 播放_Click(object sender, EventArgs e)
{
string FileName = this.textBox1.Text;
System.Diagnostics.Process process1 = new System.Diagnostics.Process();
System.Diagnostics.Process.Start("PlayWave", "\"" + FileName + "\"");？不对啊
}

你这样能用吗?

我想让DLL文件播放指定的路径的音乐,,应该怎么样才能把地址传递到DLL里面呢?

有没有大人能回答我啊？？？？

我就是不知道单击按钮里面应该怎么写?能具体的写2句吗？

[DllImport("ProWav.dll", EntryPoint = "PlayWave", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]

public static extern string PlayWave (string FileName);

private void 播放_Click(object sender, EventArgs e)
{

PlayWave("FileName");
}
我现在的程序是这样，可是他说有线程错误为什么啊？
