Console.SetWindowPosition(Int32, Int32) Console.SetWindowPosition(Int32, Int32) Console.SetWindowPosition(Int32, Int32) Console.SetWindowPosition(Int32, Int32) Method

Définition

Définit la position de la fenêtre de console par rapport à la mémoire tampon d'écran.Sets the position of the console window relative to the screen buffer.

public:
 static void SetWindowPosition(int left, int top);
public static void SetWindowPosition (int left, int top);
static member SetWindowPosition : int * int -> unit
Public Shared Sub SetWindowPosition (left As Integer, top As Integer)

Paramètres

left
Int32 Int32 Int32 Int32

Position de colonne de l'angle supérieur gauche de la fenêtre de console.The column position of the upper left corner of the console window.

top
Int32 Int32 Int32 Int32

Position de ligne de l'angle supérieur gauche de la fenêtre de console.The row position of the upper left corner of the console window.

Exceptions

left ou top est inférieur à zéro.left or top is less than zero.

- ou --or- left + WindowWidth est supérieur à BufferWidth.left + WindowWidth is greater than BufferWidth.

ou-or- top + WindowHeight est supérieur à BufferHeight.top + WindowHeight is greater than BufferHeight.

Exemples

L’exemple suivant illustre les WindowLeftpropriétés WindowTop, WindowWidth, WindowHeight, BufferWidth BufferHeight ,,CursorVisible et, et les SetWindowPosition SetBufferSizepropriétés ,et.ReadKey leurs.The following example demonstrates the WindowLeft, WindowTop, WindowWidth, WindowHeight, BufferWidth, BufferHeight, and CursorVisible properties; and the SetWindowPosition, SetBufferSize, and ReadKey methods. L’exemple dessine un modèle de grille dans la mémoire tampon d’écran en fonction de la largeur de la mémoire tampon d’écran.The example draws a grid pattern in the screen buffer based on the screen buffer width. L’exemple déplace ensuite la fenêtre de console en réponse à laquelle l’utilisateur appuie sur les touches de console flèche haut, flèche bas, flèche gauche ou flèche droite.Then the example moves the console window in response to which of the UP ARROW, DOWN ARROW, LEFT ARROW, or RIGHT ARROW console keys is pressed. Le modèle de grille vous permet de voir le déplacement de la fenêtre de console par rapport à la mémoire tampon d’écran.The grid pattern helps you see the movement of the console window relative to the screen buffer.

Remarques

La fenêtre du système d’exploitation affiche la fenêtre de console et la fenêtre de console affiche une partie de la mémoire tampon d’écran.The operating system window displays the console window, and the console window displays a portion of the screen buffer. La SetWindowPosition méthode affecte la position de la fenêtre de console par rapport à la mémoire tampon d’écran, mais n’affecte pas la position de la fenêtre du système d’exploitation par rapport au bureau.The SetWindowPosition method affects the position of the console window relative to the screen buffer, but does not affect the position of the operating system window relative to the desktop.

La console et le système d’exploitation Windows n’affectent généralement pas l’un l’autre.The console and operating system windows generally do not affect each other. Toutefois, si la mémoire tampon d’écran ne peut pas être affichée dans les limites actuelles de la fenêtre de console, le système d’exploitation ajoute automatiquement des barres de défilement à la fenêtre du système d’exploitation.However, if the screen buffer cannot be displayed in the current boundaries of the console window, the operating system automatically appends scroll bars to the operating system window. Dans ce cas, le déplacement des barres de défilement de la fenêtre du système d’exploitation affecte la position de la fenêtre de console et SetWindowPosition le déplacement de la fenêtre de console avec la méthode affecte la position des barres de défilement de la fenêtre du système d’exploitation.In that case, moving the operating system window scroll bars affects the position of the console window, and moving the console window with the SetWindowPosition method affects the position of the operating system window scroll bars.
