It is possible to convert a value type to a reference type, and back again to a value type, by using boxing and unboxing.

A value-type variable contains its data directly as opposed to a reference-type variable, which contains a reference to its data.

In general it would be unsafe to skip the run-time check if the array held elements of a reference type.

But then if you have a small member, making it a reference type incurs a pointer size overhead (plus the overhead for the reference type).

A type argument supplied to a generic type does not satisfy the reference type constraint on its corresponding type parameter.

Returns a Boolean value indicating whether an expression evaluates to a reference type.

The type argument may be a reference type, primitive type, or value type as appropriate.

If one or more of these conditions are not met, create a reference type instead of a structure.

The following example demonstrates passing a reference-type parameter, arr, by value, to a method, Change.

The original value if it is a reference type or the corresponding boxed value if it is a value type.

When copying from a value-type array to a reference-type array, each element is boxed and then copied.

In the. NET Framework, a structure is a value type and a class is a reference type.

Boxing allows any type to be treated as a reference type.

Value indicating whether an expression evaluates to a reference type.

A field can hold a value directly (value type) or hold a reference to a value (reference type).

This is in contrast to a reference type, where assignment does not create a copy.

Creates a new object or a new instance of a value type, pushing an object reference (type O) onto the evaluation stack.

This sample demonstrates passing a reference type, a value type, or a primitive type by reference to a method.

When a reference type is assigned, only the reference is copied.

We may not know what type T represents, but we know that the null literal is a valid value for any reference type.

If both arrays have reference type elements, the source element type must derive from the destination element type.

The castclass instruction attempts to cast the object reference (type O) atop the stack to a specified class.

This can lead to a problem if the XSD type is mapped to a value type in one language but mapped to a reference type in another.

If a reference type is assigned to a variable, that variable references (or "points to" ) the original value.

Any member that returns a reference type returns a handle to that object.

The supplied type must be a reference type.

A Module statement defines a reference type available throughout its namespace.

Swapping strings is a good example of passing reference-type parameters by reference.

Instruction would perform a type check in the case where! 0 Was a reference type.

Indicates that the modified reference type is a boxed value type.

For reference-type elements, this value is a null reference (Nothing).

That means a reference type can have a null pointer, but a value type cannot have a null value.

A value type can be boxed, which is a process that creates a corresponding reference type.

Boxing converts a value type to a reference type.

Whether a data type is a value type or a reference type, the communicating parties could also pose problems.

Because a managed class is a reference type, when it is passed by value, a pointer to the class is passed to unmanaged code.

So, to give you a flavor of the process, here is the challenge: How should we declare and use a CLR reference type?
