我正在尝试检查不同任务中的每个动作，并在检查是否存在碰撞后，在某些迭代中它会生成一个异常“源矩阵不够长或不够。检查索引和长度，以及较低的矩阵的极限。” 如果您尝试在“for”中按顺序运行，则不会发生错误，我需要并行运行以提高性能。在调试测试中，我注意到尝试运行 cd.DoWork() 时总是发生错误
private void btn_Tasks_Click(object sender, EventArgs e)
{
// The source of your work items, create a sequence of Task instances.
Task[] tasks = Enumerable.Range(0,tabelaPosicao.Count).Select(i =>
// Create task here.
Task.Run(() =>
{
VerifiCollision(i);
})
// No signalling, no anything.
).ToArray();
// Wait on all the tasks.
Task.WaitAll(tasks);
}
private void VerifiCollision(object x)
{
int xx = (int)x;
int AuxIncrMorsa = Convert.ToInt32(tabelaPosicao[xx].Posicao) * -1;
bRef_BaseMorsa.Transformation = new Translation(0, AuxIncrMorsa, 0);
CollisionDetection cd = new CollisionDetection(new List<Entity>() { bRef_BaseMorsa }, new List<Entity>() { bRef_Matriz }, model1.Blocks, true, CollisionDetection2D.collisionCheckType.OBWithSubdivisionTree, maxTrianglesNumForOctreeNode: 5);
