Dear friends,
I have a question about the communication between C# and
C++.
Can anyone help me ??
I have written a C# dll fies named "TestFordll2.dll",as
fllow:

using System;
namespace TestForDll2
{
    public  class TestForDll
    {
        private int result ;
        public TestForDll()
        {
            result = 0;
        }
        public TestForDll(int a , int b)
        {
            result = 0;
            result = a + b;
        }   
        public int Out()
        {
            return result;
        }       
    }
}

And I also wrote a C++ file named "Call.cpp" to call the
C# dll file "TestForDll2.dll",as follow:

#include <iostream.h>
#using <TestForDll2.dll>
#using <mscorlib.dll>
using namespace System;
using namespace TestForDll2;
int  main()
{
    int i = 0;
    TestForDll2::TestForDll *a = new
TestForDll2::TestForDll(1,2);
    i = a->Out();   
    cout<<"the result is"<<i<<endl;
   
}
And I also set the properties of the C++ file by using the
follwo:
1. Open the project's Property Pages dialog box.
Properties.
2. Click the C/C++ folder.
3. Click the General property page.
4. Modify the Resolve #using References property making
it pointing to the "TestForDll2.dll" file
when I build the project ,everyting is ok.But when I run
the project ,an error occured :can not

find file or assembly "TestForDll2",or can not find one of
its relier"
why??
Can anyone hlep me? Thanks
