无法加载 DLL“sms.dll”: 内存位置访问无效 在线等解答啊
最近在做短信发送功能，用的是GPRS，程序调试的时候，总是提示sms.dll内存位置访问无效，要不就是直接程序死掉。请大家帮忙看看问题到底出在哪里，从网上看的哪些资料都不能解决。也可能是dll的问题，大家谁有sms.dll帮忙发一个。邮箱struggle_wj@163.com，谢谢了
附上代码
动态链接库的
[STAThread]
[DllImport("sms.dll", EntryPoint = "Sms_Connection")]
public static extern uint Sms_Connection(string CopyRight, uint Com_Port, uint Com_BaudRate, out string Mobile_Type, out string CopyRightToCOM);
[DllImport("sms.dll", EntryPoint = "Sms_Disconnection")]
public static extern uint Sms_Disconnection();
[DllImport("sms.dll", EntryPoint = "Sms_Send")]
public static extern uint Sms_Send(string Sms_TelNum, string Sms_Text);
[DllImport("sms.dll", EntryPoint = "Sms_Receive")]
public static extern uint Sms_Receive(string Sms_Type, out string Sms_Text);
[DllImport("sms.dll", EntryPoint = "Sms_Delete")]
public static extern uint Sms_Delete(string Sms_Index);
[DllImport("sms.dll", EntryPoint = "Sms_AutoFlag")]
public static extern uint Sms_AutoFlag();
[DllImport("sms.dll", EntryPoint = "Sms_NewFlag")]
public static extern uint Sms_NewFlag();
/// <summary>

//thread.Start();
string TypeStr = "wavecom";
string CopyRightToCOM = "";
string CopyRightStr = "modem.COM8";
for (uint j = 1; j < 10; j++)
{
//运行到这块就报错了
uint i = SMS.Sms_Connection(CopyRightStr, (uint)j, (uint)9600, out TypeStr, out CopyRightToCOM);
if (i == 1)
{
MessageBox.Show("成功！");
}
else
{
MessageBox.Show("失败");
}
}
}
