[巨额悬赏]ASP.Net底层开发问题，调用DLL，IIS6高手入

xunyuetian 2008-03-21 03:36:47

在IIS6下使用ASP.Net[DllImport(" 调用非托管加密狗的dll,然后IIS6停止响应，
程序在IIS5下无错，执行正常，在Windows2003+VS2005下调试无错，执行正常，但是在IIS6下就出错了，症状为IIS无响应

排除加密狗DLL内部接口问题，调用代码问题，并设置IIS6服务为IIS5模式，启用了父路径,启用IIS和桌面交互的服务

IIS6

示例调用代码:
public class DllInvoke
{
//引用系统方法来取得dll路径
[DllImport("kernel32.dll")]
private extern static IntPtr LoadLibrary(String path);
[DllImport("kernel32.dll")]
private extern static IntPtr GetProcAddress(IntPtr lib, String funcName);
[DllImport("kernel32.dll")]
private extern static bool FreeLibrary(IntPtr lib);
[DllImport("user32.dll", EntryPoint = "MessageBox")]
public static extern int MessageBox(int hWnd, String strMessage, String strCaption, uint uiType);

private IntPtr hLib;
public DllInvoke(String DLLPath)
{
this.hLib = LoadLibrary(DLLPath);
}
~DllInvoke()
{
FreeLibrary(this.hLib);
}
//将要执行的函数转换为委托
public Delegate Invoke(String APIName, Type t)
{
IntPtr api = GetProcAddress(this.hLib, APIName);
return (Delegate)Marshal.GetDelegateForFunctionPointer(api, t);
}
}
--------------------
调用
DllInvoke dll = new DllInvoke(Server.MapPath(@"~/Bin/XXX.dll"));
按地址载入调用dll
XXX_GetNetState GetNetState = (XXX_GetNetState)dll.Invoke("XXX_GetNetState", typeof(XXX_GetNetState));
转换为委托方法
int status = GetNetState();
下面是传递参数例子:

问题终于解决了！使用身份模拟就可以了
public class IdentityAnalogue
{
//模拟指定用户时使用的常量定义
public const int LOGON32_LOGON_INTERACTIVE = 2;

public static extern int LogonUserA(string lpszUserName,
string lpszDomain,
string lpszPassword,
int dwLogonType,
int dwLogonProvider,
ref IntPtr phToken);
/**/
