C＃如何重复动作

Question

基本上试图缩短这个：

octree[nodeIndices[0]].nodes[nodeIndices[1]]
    .nodes[nodeIndices[2]].nodes[nodeIndices[3]].nodes[nodeIndices[4]]

我认为这样的事情可行，但不确定如何：

octree[nodeIndices[0]].(Enumerable.Repeat(node[nodeIndices[i]], 4)

编辑：这里有更多代码

OctreeNode[] nodes = octree;
ushort subdivisions = 1;

while (true)
{
    ushort nodeIndex = 0;
    OctreeNode node = nodes[nodeIndex];

    if (node == null)
    {
        node = new OctreeNode();
        node.nodes = new OctreeNode[8];
        nodes = node.nodes;
    }

    subdivisions++;

    if (subdivisions > 4)
        break;
}

// the actual octree variable is unchanged

Answer 1

var result = octree[nodeIndices[0]];

for (int i = 1; i <= 4; i++)
   result = result.node[nodeIndices[i]];

// do something with result;
