WinForm窗体之间传递参数

1.       UI设计

    主窗体FrmMain：

        两个文本框：textBox1、textBox2       存储FrmMain中的参数

        一个按钮：button1                    启动子窗体

    子窗体FrmChild：

两个文本框：textBox1、textBox2 存储FrmChild中的参数

        一个按钮：button1                    关闭子窗体，返回FrmMain

  2.      DeliveryParamsArgs类：存储从子窗体FrmChild返回到父窗体FrmMain中的参数

      


using System;


using System.Collections.Generic;


using System.Text;


using System.Collections;




namespace DeliveryParam






{


    public class DeliveryParamsArgs : EventArgs






{


        //存储参数的各种数据结构，可以自由扩展


        private ArrayList paramsList = null;


        private IDictionary<String, Object> paramsDictionary = null;




        public ArrayList ParamsList




       


{




           
get

{ return paramsList; }




           
set

{ paramsList = value; }


        }




        public IDictionary<String, Object> ParamsDictionary




       


{




           
get

{ return paramsDictionary; }




           
set

{ paramsDictionary = value; }


        }




        public DeliveryParamsArgs()




       


{


            paramsList = new ArrayList();


            paramsDictionary = new Dictionary<String, Object>();


        }


    }


}



 
3.      主窗体代码：


using System;


using System.Collections.Generic;


using System.ComponentModel;


using System.Data;


using System.Drawing;


using System.Text;


using System.Windows.Forms;




namespace DeliveryParam






{


    public partial class FrmMain : Form




   


{


        public FrmMain()




       


{


            InitializeComponent();


        }


        private string m_parm1 = null;


        private string m_parm2 = null;




        private void FrmMain_Load(object sender, EventArgs e)




       


{


           


        }




        private void button1_Click(object sender, EventArgs e)




       


{


            this.m_parm1 = this.textBox1.Text.ToString();


            this.m_parm2 = this.textBox2.Text.ToString();




            FrmChild child = new FrmChild();


           


            child.DeliveryList = new System.Collections.ArrayList();


            //将FrmMain的参数传递给FrmChild


            child.DeliveryList.Add(this.m_parm1);


            child.DeliveryList.Add(this.m_parm2);




            child.DeliveryParamsEvent += new FrmChild.DeliveryParamsHandler(child_DeliveryParamsEvent);//绑定事件


            child.Show();


        }




        void child_DeliveryParamsEvent(DeliveryParamsArgs e)




       


{


            this.textBox1.Text = e.ParamsList[0].ToString();


            this.textBox2.Text = e.ParamsList[1].ToString();


        }


    }


}



 
4.      子窗体代码：


using System;


using System.Collections.Generic;


using System.ComponentModel;


using System.Data;


using System.Drawing;


using System.Text;


using System.Windows.Forms;


using System.Collections;




namespace DeliveryParam






{


    public partial class FrmChild : Form




   


{


        public FrmChild()




       


{


            InitializeComponent();


           


        }




        //窗体FrmMain中传递过了的参数集合


        private ArrayList deliveryList = null;




        public ArrayList DeliveryList




       


{




           
get

{ return deliveryList; }




           
set

{ deliveryList = value; }


        }




        //窗体Frmchild中需要传递给FrmMain的参数


        private string c_parm1 = null;


        private string c_parm2 = null;




        private void FrmChild_Load(object sender, EventArgs e)




       


{


            this.textBox1.Text = deliveryList[0].ToString();


            this.textBox2.Text = deliveryList[1].ToString();


        }




        public delegate void DeliveryParamsHandler(DeliveryParamsArgs e);//定义委托  


        public event DeliveryParamsHandler DeliveryParamsEvent;//定义事件




        private void button1_Click(object sender, EventArgs e)




       


{


            DeliveryParamsArgs arrayParams = new DeliveryParamsArgs();


            this.c_parm1 = this.textBox1.Text.ToString();


            this.c_parm2 = this.textBox2.Text.ToString();




            arrayParams.ParamsList.Add(this.c_parm1);


            arrayParams.ParamsList.Add(this.c_parm2);




            arrayParams.ParamsDictionary.Add("c_parm1", this.c_parm1);


            arrayParams.ParamsDictionary.Add("c_parm2", this.c_parm2);




            //激发事件，写在你想要的地方  


            if (DeliveryParamsEvent != null)




           


{


                DeliveryParamsEvent(arrayParams);


            }


            this.Close();


            this.Dispose();


        }


    }


}
