下面是使用测试

 

//SinASDL asdl = new SinASDL("宽带连接", "08793312221", "123456");  //宽带连接
//使用枚举到的第一个进行拨号
SinASDL asdl = new SinASDL(SinASDL.GetASDLNames()[0], "08793312221", "123456", System.Diagnostics.ProcessWindowStyle.Normal);
if (asdl.Connect() == 0)
{
    MessageBox.Show("Success");
}
else
{
    MessageBox.Show("Fail");
}
