Console.SetWindowPosition(Int32, Int32) Metode

Definisi

Ruang nama:

System

Rakitan:

netstandard.dll, System.Console.dll

Sumber:

Console.cs

Mengatur posisi jendela konsol relatif terhadap buffer layar.

public:
 static void SetWindowPosition(int left, int top);

[System.Runtime.Versioning.SupportedOSPlatform("windows")]
public static void SetWindowPosition(int left, int top);

[<System.Runtime.Versioning.SupportedOSPlatform("windows")>]
static member SetWindowPosition : int * int -> unit

Public Shared Sub SetWindowPosition (left As Integer, top As Integer)

Parameter

left

Int32

Posisi kolom sudut kiri atas jendela konsol.

top

Int32

Posisi baris sudut kiri atas jendela konsol.

Atribut

SupportedOSPlatformAttribute

Pengecualian

ArgumentOutOfRangeException

left atau top kurang dari nol.

-atau-

left + WindowWidth lebih besar dari BufferWidth.

-atau-

top + WindowHeight lebih besar dari BufferHeight.

SecurityException

Pengguna tidak memiliki izin untuk melakukan tindakan ini.

IOException

Terjadi kesalahan I/O.

PlatformNotSupportedException

Sistem operasi saat ini bukan Windows.

Contoh

Contoh berikut menunjukkan WindowLeftproperti , , WindowTop, WindowWidthWindowHeight, BufferWidth, BufferHeightdan CursorVisible ; dan SetWindowPositionmetode , SetBufferSize, dan ReadKey . Contoh menggambar pola kisi di buffer layar berdasarkan lebar buffer layar. Kemudian, contoh memindahkan jendela konsol sebagai respons terhadap tombol konsol PANAH ATAS, PANAH BAWAH, PANAH KIRI, atau PANAH KANAN ditekan. Pola kisi membantu Anda melihat pergerakan jendela konsol relatif terhadap buffer layar.

Keterangan

Jendela sistem operasi menampilkan jendela konsol, dan jendela konsol menampilkan sebagian buffer layar. Metode ini SetWindowPosition memengaruhi posisi jendela konsol relatif terhadap buffer layar, tetapi tidak memengaruhi posisi jendela sistem operasi relatif terhadap desktop.

Konsol dan jendela sistem operasi umumnya tidak mempengaruhi satu sama lain. Namun, jika buffer layar tidak dapat ditampilkan di batas jendela konsol saat ini, sistem operasi secara otomatis menambahkan bilah gulir ke jendela sistem operasi. Dalam hal ini, memindahkan bilah gulir jendela sistem operasi memengaruhi posisi jendela konsol, dan memindahkan jendela konsol dengan SetWindowPosition metode memengaruhi posisi bilah gulir jendela sistem operasi.
