InstallShield高手请进．高分回答。如何在InstallScript中调用VC#.net开发的组件？？？

[wuxinjiang]

VC#开发的DLL中的函数式在一个类中的
请问在InstallScript中应该怎么调用DLL类中的一个函数呢

[xiaohuidong]

prototype [CallingConvention] [ReturnType] DLLName.FunctionName( ParamType1, ParamType2, ... );

[xiaohuidong]

For example:

1. prototype BOOL MyDLL.MyFunction( INT, INT, INT );
2. UseDLL( SUPPORTDIR ^ "MyDLL.dll" );
3. bResult = MyDLL.MyFunction( nInt1, nInt2, nInt3 );

[kingzai]

#define DLL_FILE "MyDLL.dll;"



// Prototype MydllReturn in Mydll.dll.

prototype Mydll.MydllReturn (INT, BYREF STRING);



STRING svString;

INT nValue;

NUMBER nResult;

BOOL bDone;



#include "ifx.h"

program



// Load the dll into memory.

nResult = UseDLL (DLL_FILE);



if (nResult = 0) then

MessageBox ("UseDLL successful \n\n.DLL file loaded.", INFORMATION);

else

MessageBox ("UseDLL failed.\n\nCouldn't load .DLL file.", INFORMATION);

abort;

endif;



// bDone controls the following while loop.

bDone = FALSE;



// Loop while bDone is FALSE.

while (bDone = FALSE)



// Disable the Back button in setup dialogs.

Disable (BACKBUTTON);



// Get a string from the euser.

AskText ("Enter an example string.", "Example string.", svString);



// Get the string length to pass to MydllReturn.

nValue = StrLength (svString);



// Call MydllReturn.

MydllReturn (nValue, svString);



// Display the string to observe how it was altered by MydllReturn.

SprintfBox (INFORMATION, "UseDLL", "MydllReturn() changed the string " +

"to: %s", svString);



// Give the user a chance to do another example.

if (AskYesNo ("Do another example?", YES) = NO) then

bDone = TRUE;

endif;



endwhile;



// Remove the dll from memory.

if (UnUseDLL (DLL_FILE) < 0) then

MessageBox ("UnUseDLL failed.\n\nDLL still in memory.", SEVERE);

else

MessageBox ("UnUseDLL successful.\n\n.DLL file removed from memory.",

INFORMATION);

endif;



endprogram

www.installsite.org上有各种例子！

[wuxinjiang]

我还是不明白，一个C#的DLL文件中首先有一个命名空间，命名空间中包含一个类，类中才包含一个函数，我总不会直接用DLL文件名就调用其中的函数吧。
谁能不能提供一个VC# 开发DLL的简单例子然后给出在InstallScript中的调用方法呢？送满分
