All values in Python are references. What you need to worry about is if a type is mutable. The basic numeric and string types, as well as tuple and frozenset are immutable; names that are bound to an object of one of those types can only be rebound, not mutated. >>> t = 1, 2, … Read more
Yes, you can. The pointer to the class member variable is stored on the stack with the rest of the struct’s values, and the class instance’s data is stored on the heap. Structs can also contain class definitions as members (inner classes). Here’s some really useless code that at least compiles and runs to show … Read more
In which case should you use primitive types(int) or reference types (Integer)? As a rule of thumb, I will use a primitive (such as int) unless I have to use a class that wraps a primitive. One of the cases were one must use a wrapper class such as Integer is in the case of … Read more
Guid is a Value Type. See MSDN. Note that Guid is a struct. All structs are Value Types.
The question boils down to this: the CLI (Common Language Infrastructure) specification says that delegates are reference types. Why is this so? One reason is clearly visible in the .NET Framework today. In the original design, there were two kinds of delegates: normal delegates and “multicast” delegates, which could have more than one target in … Read more
For mapping between two types where you’re taking control of the entire mapping, use ConvertUsing: Mapper.CreateMap<MyEnum, string>().ConvertUsing(src => src.ToString()); All the other methods assume you’re mapping to individual members on the destination type.
Cause of this error -You are trying to pass a primitive object into a generic type declaration whereas generic types always expect a Wrapper Class object. So please use ‘Boolean’ instead of ‘boolean’ in your code i.e. ‘B’ in caps.
What you’re looking for are object id’s. For any referenc type in the debugger you can right click and say “Make Object ID”. This will add a # suffix to the value column whenever that instance is displayed in the debugger. You can also add #1, #2, etc … to the watch window to see … Read more
System.Enum is a reference type, but any specific enum type is a value type. In the same way, System.ValueType is a reference type, but all types inheriting from it (other than System.Enum) are value types. So if you have an enum Foo and you want a nullable property, you need the property type to be … Read more
Is tricky. Will come onto it in a minute. There’s no difference – in both cases, it’s the variable itself which is captured. Nope, no boxing occurs. It’s probably easiest to demonstrate how the capturing works via an example… Here’s some code using a lambda expression which captures a single variable: using System; class Test … Read more
