.Net语言 APP开发平台——Smobiler学习日志：如何快速实现Timer计时功能

一、目标样式

1.从工具栏上的”Smobiler Components”拖动一个Timer控件、一个TextBox控件、一个Button控件、一个label控件和一个Image控件到窗体界面上

2.Timer控件的Tick事件

VB：    Private Sub timer1_Tick(sender As Object, e As EventArgs) Handles timer1.Tick
Me.TextBox1.Text = (Convert.ToInt32(Me.textBox1.Text.ToString()) - 1).ToString()
End Sub

C#:   private void timer1_Tick(object sender, EventArgs e)   {       this.textBox1.Text =(Convert.ToInt32(this.textBox1.Text.ToString()) -1).ToString();
}

3.TextBox的TextChanged事件

VB：   Private Sub textBox1_TextChanged(sender As Object, e As EventArgs) Handles textBox1.TextChanged
If Me.textBox1.Text = "0" Then           timer1.Stop()
Else           timer1.Start()
End If
End Sub

C#:   private void textBox1_TextChanged(object sender, EventArgs e)   {        if(this.textBox1.Text =="0")
{
timer1.Stop();
}       else
{
timer1.Start();
}
}

4.Button控件的Click事件

VB：   Private Sub button1_Click(sender As Object, e As EventArgs) Handles button1.Click
Me.textBox1.Text = "60"
End Sub

C#:   private void button1_Click(object sender, EventArgs e)   {        this.textBox1.Text ="60";
}

5.修改Timer控件的属性

a.Interval属性
