如何使用委托实例
private delegate void WriteIntoTextBox(string s);
private WriteIntoTextBox write;
public DelegateTest1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
if (checkBox1.Checked == true)
{
textBox1.Clear();
textBox1.Refresh();
// 实例化委托
write = new WriteIntoTextBox(WriteTextBox1);
// 作为参数
WriteText(write);
textBox3.Focus();
textBox3.SelectAll();
}
if (checkBox2.Checked == true)
{
textBox2.Clear();
textBox2.Refresh();
// 实例化委托
write = new WriteIntoTextBox(WriteTextBox2);
// 作为参数
WriteText(write);
textBox3.Focus();
textBox3.SelectAll();
}
