Sam works as a Software Developer for GenTech Inc. The company uses Visual Studio .NET as its application development platform. Sam develops an application named App1 using Visual C# .NET. App1 uses a non-COM DLL named Value1.dll, which contains unmanaged code. Sam wants to write a method named Method1 in Value1.dll. He wants to use Method1 for parsing a string into an array of string values and an array of numbers. He decides to specify three parameters for Method1.
