?i really want to know how to give refrence of C dll in C# dll.

System.Globalization.CultureInfo ci = System.Threading.Thread.CurrentThread.CurrentCulture;
string decimalSeparator = ci.NumberFormat.CurrencyDecimalSeparator;

If you try to forcable pass a value type by reference, what is happening behind the scences is the value type is being stuck in a reference type box (refereed to as being 'boxed') and it is a reference to this box that is passed.

Why do you want to pass a reference type by value?
