Convert From C# VS2010 - get_Item & set_Value in C++/CLI

Hi,
I wish to convert from c# for the following codes contain get_Item & set_Value convertion in C++/Cli.

Code:

---

 
private static void SetWIAProperty(IProperties properties, object propName, object propValue)
{
        Property prop = properties.get_Item(ref propName);
        prop.set_Value(ref propValue);
}

---

Any guidences will be helpful.

Thanks

How (and where) are IProperties and Property defined? They do not seem to be part of the .NET framework.

Can you post the original C# code you are translating?

I can't remember any scenario, where application code explicitly calls these "generic" property accessors. However, assuming IProperties has a property Item, presumably of type Object ^, the accessor signatures would be Object ^IProperty::Item::get() and void IProperty::Item::set(Object ^value), if I recall correctly. In concrete code you would replace IProperty:: by, say, properties-> and pass the appropriate ref class reference (i.e. instance) to the setter. However, I'm not sure that would ever compile in any real-life code.

Thanks Eri. Until my breath I will be remember your help Mr.Eri. Because All my Visual C++ code behind your helps were there.
Now I am in need to scan the invoice & store it to Access Database. For that I found the following c# code to scan.
