Winform的一些玩法

一、窗体透明

private void Form1_Load(object sender, EventArgs e) { this.BackColor = Color.White; this.TransparencyKey = Color.White; this.Opacity = 1; }

二、子窗体向父窗体传值（委托） 子窗体

public delegate void PutHandler(string text); public PutHandler putTextHandler;//委托对象 private void button1_Click(object sender, EventArgs e) { if (putTextHandler != null) { putTextHandler(textBox1.Text.ToString()); } }

父窗体

public void getValue(string strV) { this.textBox1.Text = strV; } private void button1_Click(object sender, EventArgs e) { FormSon fs = new FormSon(); fs.putTextHandler = getValue; fs.ShowDialog(); }
