C#中是否存在针对DirectX的接口?

Question

DirectX Interoperability Technology SampleThis suite of samples shows the .NET Framework interoperability features by using the DirectX components DirectDraw and DirectMusic.Readme Locations
For more information, see the Readme files at <SDK>v1.1\Samples\Technologies\Interop\Basic\DirectX\DirectDraw and<SDK>v1.1\Samples\Technologies\Interop\Basic\DirectX\DirectMusic

Answer 1

this is VB, C# is same.

Answer 2

去下一个DirectX的.net开发包,在英文的msdn上，里面有例子。

Answer 3

记得DirectX9下有.net的开发包了。

Answer 4

using Microsoft.DirectX;
using Microsoft.DirectX.DirectDraw;
        private void InitializeDirectDraw()
        {
            SurfaceDescription description = new SurfaceDescription(); // Describes a surface.
            Random randomNumber = new Random(); // Random number for position and velocity.
            ColorKeyFlags flags = new ColorKeyFlags();            displayDevice = new Device(); // Create a new DirectDrawDevice.
            displayDevice.SetCooperativeLevel(this, CooperativeLevelFlags.FullscreenExclusive); // Set the cooperative level.            try
            {
                displayDevice.SetDisplayMode(screenWidth, screenHeight, 8, 0, false); // Set the display mode width and height, and 8 bit color depth.
            }
            catch(UnsupportedException)
            {
                MessageBox.Show("Device doesn't support required mode. Sample will now exit.", "UnsupportedException caught");

                return;

            back = front.GetAttachedSurface(caps); // Get the attached surface that matches the caps, which will be the backbuffer.            pal = new Palette(displayDevice, bitmapFileName); // Create a new palette, using the bitmap file.
            pe = pal.GetEntries(0, 256); // Store the palette entries.
            front.Palette = pal; // The front surface will use this palette.

            text = new Surface(description, displayDevice); // Create the surface using the above description.
            text.ForeColor = Color.FromArgb(indexWhite); // Because this is a palettized environment, the app needs to use index based colors, which
                                                         // do not correspond to pre-defined color values. For this reason, the indexWhite variable exists
                                                         // and contains the index where the color white is stored in the bitmap's palette. The app makes use
                                                         // of the static FromArgb() method to convert the index to a Color value.
            text.ColorFill(indexBlack);
            text.DrawText(0, 0, textHelp, false);            for (int i=0; i < numSprites; i++)

                sprite[i].posX = (randomNumber.Next()  % screenWidth);
                sprite[i].posY = (randomNumber.Next() % screenHeight);                 sprite[i].velX = 500.0f * randomNumber.Next() / Int32.MaxValue - 250.0f;
                sprite[i].velY = 500.0f * randomNumber.Next() / Int32.MaxValue - 250.0f;
            }

Answer 5

有.net的开发包,MSDN上面也有类似的例子。

Answer 6

有，dx9有，我用过的，是2003summer版的发布的sdkupdate里开始有了

Answer 7

2003summer里的那个例子可以给我发一个吗？我装的2004里面没有例子
