C# 动态创建出来的窗体间的通讯 delegate1

附件 http://files.cnblogs.com/xe2011/CSharp_WindowsForms_delegate01.rar

 

需要每个窗体是独立存在，禁止相与引用窗体

这样干净并且可以反复重用

 

 

Form1的代码

      private void button1_Click(object sender, EventArgs e)

        {

            Form2 f2 = new Form2();

            f2.XYZ += new Form2.CallBack(GetForm2TextBox1Text);

            f2.Show();

        }



        void GetForm2TextBox1Text(string s)

        {

            textBox1.Text = s;

        }

 

Form2

        public delegate void CallBack(string s);

        public event CallBack XYZ;

        private void textBox1_TextChanged(object sender, EventArgs e)

        {

            XYZ(textBox1.Text);

        }
