directx尝试读取或写入受保护的内存。这通常指示其他内存已损坏

Question

render()//渲染函数
{
List<Mesh> Meshs = ToMesh(verts);
            for (int i = 0; i < Meshs.Count; i++)
            {
                if (Meshs[i] != null)
                {
                   Meshs[i].DrawSubset(0);
                }
            }
}执行一会，在Meshs[i].DrawSubset(0);报错：
