C# SlimDX，SwapChain.ResizeBuffers（…）错误？

我对方法“SwapChain.ResizeBuffers（…）”有一个问题，每当我调用它时都会出现错误。。。基本上，我想做的是：我希望能够动态更改渲染分辨率，所以当我更改了_RenderingWidth和_RenderingHeight的值时，我调用这个方法（如下所示）

    protected override void UpdateResolution()
    {
        if (_RenderTargetView != null) _RenderTargetView.Dispose();
        if (_BackBuffer != null) _BackBuffer.Dispose();

        _Device.OutputMerger.SetTargets((RenderTargetView) null);

        _SwapChain.ResizeBuffers(_SwapChain.Description.BufferCount, _RenderingWidth, _RenderingHeight, _SwapChain.Description.ModeDescription.Format, _SwapChain.Description.Flags);

        _BackBuffer = Texture2D.FromSwapChain<Texture2D>(_SwapChain, 0);
        _RenderTargetView = new RenderTargetView(_Device, _BackBuffer);

        _Device.OutputMerger.SetTargets(_RenderTargetView);
    }

我的声明：

    protected SlimDX.Direct3D10_1.Device1 _Device = null;
    protected SwapChain _SwapChain = null;

    protected Texture2D _BackBuffer = null;
    protected RenderTargetView _RenderTargetView = null;

[编辑] 我想出来了：

    var description = _SwapChain.Description;

    if (_RenderTargetView != null) _RenderTargetView.Dispose();
    if (_BackBuffer != null) _BackBuffer.Dispose();

    _SwapChain.Dispose();

    description.ModeDescription = new ModeDescription(_RenderingWidth, _RenderingHeight, new Rational(160, 1), Format.B8G8R8A8_UNorm);
    _SwapChain = new SwapChain(_Factory_DXGI, _Device, description);

    _BackBuffer = Texture2D.FromSwapChain<Texture2D>(_SwapChain, 0);
    _RenderTargetView = new RenderTargetView(_Device, _BackBuffer);

    _Device.OutputMerger.SetTargets(_RenderTargetView);

var description=\u SwapChain.description；
如果（_RenderTargetView！=null）_RenderTargetView.Dispose（）；
如果（_BackBuffer！=null）_BackBuffer.Dispose（）；
_SwapChain.Dispose（）；
description.ModeDescription=newmodedescription（_RenderingWidth，_RenderingHeight，new Rational（160，1），Format.B8G8R8A8_UNorm）；
_SwapChain=新的SwapChain（_工厂_DXGI，_设备，说明）；
_BackBuffer=来自SwapChain的纹理2d（_SwapChain，0）；
_RenderTargetView=新的RenderTargetView（_设备，_Backuffer）；
_Device.outputMerge.SetTargets（_RenderTargetView）；

重新开始一切。。。不知道为什么我以前没想到这个

你不需要重新控制交换链。看见

    var description = _SwapChain.Description;

    if (_RenderTargetView != null) _RenderTargetView.Dispose();
    if (_BackBuffer != null) _BackBuffer.Dispose();

    _SwapChain.Dispose();

    description.ModeDescription = new ModeDescription(_RenderingWidth, _RenderingHeight, new Rational(160, 1), Format.B8G8R8A8_UNorm);
    _SwapChain = new SwapChain(_Factory_DXGI, _Device, description);

    _BackBuffer = Texture2D.FromSwapChain<Texture2D>(_SwapChain, 0);
    _RenderTargetView = new RenderTargetView(_Device, _BackBuffer);

    _Device.OutputMerger.SetTargets(_RenderTargetView);
