struct 套用 创建

Question

public struct File_Pa 
{ 
     public NumOfTreatmentUnits []aa
} 
public struct NumOfTreatmentUnits 
{ 
     public struct TreatmentUnit {..} } 假如aa[3]我怎么创建 TreatmentUnit 

Answer 1

struct MyStruct1
{
    public struct MyStruct2
    {
        public int i;
    }
}
class main
{
    static void Main()
    {
        MyStruct1.MyStruct2 s;
        s.i = 10;
        Console.WriteLine(s.i);
    }
}

Answer 2

public struct NumOfTreatmentUnits
        {
            public struct TreatmentUnit 
            {
                .........
            }            public TreatmentUnit tt; //
                   }   

Answer 3

在 struct   NumOfTreatmentUnits  中你只是声明了 struct   TreatmentUnit   

Answer 4

谢谢三位的回答
可能我表达不清晰：
File_Pa 里面包含了 struct  NumOfTreatmentUnits   注意是一个数组。。  
而 NumOfTreatmentUnits    里面又有很多 struct 例如我说的   TreatmentUnit       我要达到的效果是：
File_Pa.NumOfTreatmentUnits[1].  TreatmentUnit .aa=X
File_Pa.NumOfTreatmentUnits[2].  TreatmentUnit .aa=Y怎么解决呢？

Answer 5

       public   struct   File_Pa   
        {
            public NumOfTreatmentUnits[] aa;
         } 
        public   struct   NumOfTreatmentUnits   
        { 
          public   struct   TreatmentUnit   
          {
              public int a;
              public int b;
          }
           public TreatmentUnit tre;     
        }赋值              File_Pa pa;
            pa.aa = new NumOfTreatmentUnits[6];
            pa.aa[1].tre.a = 4;
            pa.aa[1].tre.b = 9;
