¿Por qué las estructuras son tipos de valor?

Why structs are value types?

Structs are value types, while classes are reference types, and the runtime deals with the two in different ways. When a value-type instance is created, a single space in memory is allocated to store the value. p2, being a struct, becomes an independent copy of p1, with its own separate fields.

C# provides the following built-in value types, also known as simple types:

• Integral numeric types.
• Floating-point numeric types.
• bool that represents a Boolean value.
• char that represents a Unicode UTF-16 character.

In this article Variables of reference types store references to their data (objects), while variables of value types directly contain their data. With reference types, two variables can reference the same object; therefore, operations on one variable can affect the object referenced by the other variable.

A struct can contain properties, auto-implemented properties, methods, etc., same as classes. The following struct includes the static method.

Libgdiplus is the Mono library that provides a GDI+-compatible API on non-Windows operating systems. Our implementation uses Cairo to do most of the heavy lifting. Mono’s implementation of GDI+ lives in the libgdiplus GitHub repository.

Sidewalk Art

1. Cut a sheet of paper that is longer than the height of your friend. (Or, tape sheets of paper together.)
2. Place the paper on a hard, smooth floor.
3. Next, draw the different parts of the nervous system.
4. Hang the drawing on a wall or inside your closet door to show off your nerves!

C# is a strongly typed language. Every variable and constant has a type, as does every expression that evaluates to a value. Every method declaration specifies a name, number of parameters, and type and kind (value, reference, or output) for each input parameter and for the return value.

System.Drawing.Point represents a GDI point and is used in Windows Forms. It can only hold integer values. WPF doesn’t use GDI anymore, so it has its own System.Windows.Point type to represents a point, which can have non integer values. System.Windows.Point has additional methods like Parse. – D.Rosado Mar 30 ’12 at 10:53

System. Drawing Represents an ordered pair of integer x- and y-coordinates that defines a point in a two-dimensional plane. The following code example creates points and sizes using several of the overloaded operators defined for these types. It also demonstrates how to use the SystemPens class.

I guess you’d have got InvalidCastException, you can’t just cast one type to another unless implicit or explicit conversion exist between them. Remember cast is different and convert is different. Following code converts System.Drawing.Point to System.Windows.Point and viceversa.

Gets or sets the x-coordinate of this PointF. Gets or sets the y-coordinate of this PointF. Translates a given PointF by the specified Size. Translates a given PointF by a specified SizeF. Specifies whether this PointF contains the same coordinates as the specified Object.
