1 用属性传值

(子窗体)

PRivate ArrayList arrlOut;

public ArrayList arrlIn//要用pulibc

        {
            set
            {
                this .arrlOut    = value;//这里不能用arrlIn而要单独声明一个变量
            }
            get
            {
                return this .arrlOut  ;
            }
        }

(主窗体,由它向子窗体传传值)

using System.Collections;//ArrayList引用空间

private  ArrayList arrlOut;

private void btnShowForm4_Click(object sender, EventArgs e)
        {
            Form4 form4StudentInformation = new Form4();
            form4StudentInformation.arrlIn  = this.arrlOut ;
            form4StudentInformation.Show();
        }

2用方法传值

(主窗体)

using System.Collections;//ArrayList引用空间

private  ArrayList arrlOut;

private void btnShowForm3_Click(object sender, EventArgs e)
        {
            Form3 formStudentInformation = new Form3();
            formStudentInformation.setArray(arrlOut);
            formStudentInformation.Show();
        }

(子窗体)

private ArrayList arrlOut;

public  void setArray(ArrayList arrayin)//要用pulibc
        {
            arrlOut = arrayin;


        }

3构造函数传值

(子窗体)

private ArrayList arrlOut;
        public studentOneInformationForm(ArrayList   arrlIn)//构造函数中加了参数
        {
            InitializeComponent();
            arrlOut = arrlIn;
        }

(主窗体)

private void showFormInformation_Click(object sender, EventArgs e)
        {
            studentOneInformationForm studentOne = new studentOneInformationForm(this.arrlOut);//传参数
            studentOne.Show();

        }
