调用dll时找不到函数

[hcyang]

dll代码：
using System.Security.Permissions;

[System.AttributeUsageAttribute(System.AttributeTargets.Class|System.AttributeTargets.Struct, AllowMultiple=true)]
public class Author : System.Attribute {
public static void Main() {}
public Author(string name) { this.name = name; version = (float) 1.0; }
public Author(int name) {}
public Author() {}
public float version;
private string name;
public int[] rgnField;
public double [] rgdField;
}

[System.Security.Permissions.PermissionSetAttribute(SecurityAction.Demand)]
[ABC(SomeStuff.e17)]
[ABC(1, rgdField=new double[2] {6, 1.2})]
[ABC, ABC("99"), ABC(1, rgnField=new int[2] {1, 2})]
[ABC, ABC("99"), Author(1, rgnField=new int[2] {1, 2})]
public class MYStuff {
}

vc中代码：
HINSTANCE hInst = LoadLibrary("Author.dll");
typedef (*MYFUNC)(int name);
MYFUNC fun;
fun = (MYFUNC)GetProcAddress(hInst, "Author");
if(fun != NULL)
{
cout << fun(30) << endl;
}
FreeLibrary(hInst);

这样写找不到Author这个函数，请问是什么原因，thanks

这个是托管的dll来的，好像不能直接导出吧。
.Net的东东好久没碰了，对不起，帮不了你
