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

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();       
   }

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();
       }
   }

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";      
   }
