无法访问form2中的公共静态类 [英] Could not reach public static class in form2

问题描述

你好

i有2个表单，form1在class里面有classe，我在form1中生成那些类的公共静态数组。

static public father [] xx = new father [3]; //< ----见下面代码中的A行

在form2中我写了

int saveIn;

saveIn = Form1.xx [0] .P [0] .V [0] .X;

progrm没有运行错误是

不一致的可访问性：字段类型'test.Form1.father []'比字段'test.Form1.xx'更难以访问



我怎么能重新定义上面的类才能拥有该程序很多，谢谢



我尝试过：

 //类在form1 
类MyNum 
 {
 private int x; 
 public MyNum（）{} 
 public MyNum（int Xx）{X = Xx; } 
 public int X {get {return x; } set {x = value; } 
} // MyNum 
类Sun 
 {
 public int n; 
 public MyNum [] V; 
 public Sun（）{} 
 public Sun（int Xn）{N = Xn; } 
 public int N {get {return n; } set {n = value; 
 public MyNum this [int i] 
 {get {return V [i]; } set {V [i] = value; } 
} // MyLine 
 class father 
 {
 public int x; 
 public Sun [] P; 
 public father（）{} 
 public father（int Xx）{X = Xx; } 
 public int X {get {return x; } set {x = value; 
 public Sun this [int i] {get {return P [i]; } {P [i] = value; } 
} //父亲
静态公共父亲[] xx =新父亲[3]; //< --------------行A 
 //下面的行在Form_2_Load 
 int SaveInt; 
 saveInt = Form1.xx [0] .P [0] .V [0] .X; 
 

解决方案

C＃区分大小写;这两行不是指同一个变量：

 int SaveInt; 
 saveInt = Form1.xx [0] .P [0] .V [0] .X; 
 

修复它，它会编译。

它不起作用 - 你会得到空引用错误，因为你没有在数组 xx 中创建任何父实例 - 但它会编译。

你也需要这样的东西：

  for （ int  i =  0 ; i <   3 ; i ++）
 {
 xx [i] =  new  father（）; 
} 

我应该将该类声明为公开类似

公共类父亲

Hello
i have 2 forms ,form1 has classe inside class ,i generate public static array of those classes in form1.
static public father[] xx = new father[3];//<----see line A in the code below
In form2 i wrote
int saveIn;
saveIn = Form1.xx[0].P[0].V[0].X;
the progrm did not run the error is
Inconsistent accessibility: field type 'test.Form1.father[]' is less accessible than field 'test.Form1.xx'

how could i redefine the above classes in order to have the program run ?
many thanks

What I have tried:

//Classes are in form1
    class MyNum
    {
        private int x;
        public MyNum() { }
        public MyNum(int Xx) { X = Xx; }
        public int X { get { return x; } set { x = value; } }
    }//MyNum
    class Sun
    {
        public int n;
        public MyNum[] V;
        public Sun() { }
        public Sun(int Xn) { N = Xn; }
        public int N { get { return n; } set { n = value; } }
        public MyNum this[int i]
        { get { return V[i]; } set { V[i] = value; } }
    }//MyLine
    class father
    {
        public int x;
        public Sun[] P;
        public father() { }
        public father(int Xx) { X = Xx; }
        public int X { get { return x; } set { x = value; } }
        public Sun this[int i] { get { return P[i]; } set { P[i] = value; } }
    }//father
    static public father[] xx = new father[3];//<--------------Line A
    // the line below is in Form_2_Load
         int SaveInt;
     saveInt = Form1.xx[0].P[0].V[0].X;

解决方案

C# is case sensitive; these two lines do not refer to the same variable:

int SaveInt;
saveInt = Form1.xx[0].P[0].V[0].X;

Fix that, and it'll compile.
It won't work - you'll get null reference errors because you haven't created any father instances in the array xx - but it'll compile.
You need to something like this as well:

for (int i = 0; i < 3; i++)
   {
   xx[i] = new father();
   }

i should declare the class as public like

public class father
