我试图从内存中的数据创建SharpDX.Direct3D11.Texture2D,但总是得到一个SharpDXException (HRESULT: 0x80070057,“该参数不正确。”)。为此,我使用了一个Texture1D,在此之前创建它不会有任何问题。
我已经将代码简化为以下示例,它仍然会产生异常:
using (var device = new Device(DriverType.Hardware, DeviceCreationFlags.Debug)) {
// empty stream sufficient for example
var stream = new DataStream(16 * 4, true, true);
var description1D = new Texture1DDescription() {
Width = 16,
ArraySize = 1,
Format = Format.R8G8B8A8_UNorm,
MipLevels = 1,
};
using (var texture1D = new Texture1D(device, description1D, new[] { new DataBox(stream.DataPointer) })) {
// no exception on Texture1D
}
var description2D = new Texture2DDescription() {
Width = 8,
Height = 2,
ArraySize = 1,
MipLevels = 1,
Format = Format.R8G8B8A8_UNorm,
SampleDescription = new SampleDescription(1, 0),
};
using (var texture2D = new Texture2D(device, description2D, new[] { new DataBox(stream.DataPointer) })) {
// HRESULT: [0x80070057], Module: [Unknown], ApiCode: [Unknown/Unknown], Message: The parameter is incorrect.
}
}在不传递数据的情况下创建纹理效果良好。有人能告诉我如何修复Texture2D初始化吗?

您需要将2D纹理的行跨距传递到DataBox中。类似于:
new DataBox(stream.DataPointer, 8 * 4)或者以更通用的方式:
new DataBox(stream.DataPointer, description2D.Width
* (int)FormatHelper.SizeOfInBytes(description2D.Format))https://stackoverflow.com/questions/13261427
