c#如何实现以下效果？

C# code

PosGroup.Lane.Row[m].Col[n].Layer[h].Pos.PosState = Convert.ToInt32(ds1.Tables[0].Rows[i]["Pos_State"]);

[解决办法]
把 for(int m=0;m<=IRow;m++) 循环整个换成下面的代码，看哪行出的错

C# code

var lane = PosGroup.Lane;var row = lane.Row;for (int m = 0; m <= IRow; m++){    PosGroup.Lane.Row[m] = new TRow();    for (int n = 0; n <= ICol; ICol++)    {        PosGroup.Lane.Row[m].Col[n] = new TCol();        for (int h = 0; h <= ILayer; h++)        {            PosGroup.Lane.Row[m].Col[n].Layer[h] = new TLayer();            PosGroup.Lane.Row[m].Col[n].Layer[h].Pos.PosState = Convert.ToInt32(ds1.Tables[0].Rows[i]["Pos_State"]);            PosGroup.Lane.Row[m].Col[n].Layer[h].Pos.Zone_ID = Convert.ToInt32(ds1.Tables[0].Rows[i]["Zone_ID"]);            PosGroup.Lane.Row[m].Col[n].Layer[h].Pos.PID = Convert.ToInt32(ds1.Tables[0].Rows[i]["PID"]);            PosGroup.Lane.Row[m].Col[n].Layer[h].Pos.HasSetValue = true;        }    }}
