ダイナミックラベルのC＃リフレッシュ値

Question

私は質問したいと思います。私はこのコードを持っていて、自分のダイナミックラベルを別のラベルに積み重ねることなく値をリフレッシュするようにしたいと思っています。

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace refresh_label 
{ 
    public partial class Form1 : Form 
    { 
     Int64 num1 = 0; 
     public Form1() 
     { 
      InitializeComponent(); 
     } 

     private void Form1_Load(object sender, EventArgs e) 
     { 
      Timer t1 = new Timer(); 
      t1.Interval = 1; 
      t1.Tick += new EventHandler(lbl_refresh); 
      t1.Enabled = true; 
      Label lbl = new Label(); 
      lbl.Text = num1.ToString(); 
      this.Controls.Add(lbl); 
     } 

     private void lbl_refresh(object sender, EventArgs e) 
     { 
      num1++; 
     } 
    } 
} 

//on this one it's working but staking labels. is there a way to refresh the label without staking it and then clear it? thank you for your time. 

private void Form1_Load(object sender, EventArgs e) 
{ 

    Timer t1 = new Timer(); 
    t1.Interval = 1; 
    t1.Tick += new EventHandler(lbl_refresh); 
    t1.Enabled = true; 
} 

private void lbl_refresh(object sender, EventArgs e) 
{ 
    num1++; 

    Label lbl = new Label(); 
    lbl.Text = num1.ToString(); 
    this.Controls.Add(lbl); 
    lbl.BringToFront(); 
} 

Answer 1

これを試してみてください - 新しいラベル毎回作成する必要がない初心者のための

private void lbl_refresh(object sender, EventArgs e) 
{ 
    num1++; 

    lbl.Text = num1.ToString(); 
    lbl.Update(); 
}

Int64 num1 = 0; 
    public Form1() 
    { 
     InitializeComponent(); 
    } 
    private void Form1_Load(object sender, EventArgs e) 
    { 
     Timer t1 = new Timer(); 
     t1.Interval = 1; 
     t1.Tick += new EventHandler(lbl_refresh); 
     t1.Enabled = true; 
     Label lbl = new Label(); 

     lbl.Name="myLabel"; 
     lbl.Text = num1.ToString(); 
     this.Controls.Add(lbl); 
    } 

    private void lbl_refresh(object sender, EventArgs e) 
    { 
     Label l = Controls.Find("myLabel",true)[0] as Label; 
     l.Text = num1.ToString(); 
     num1++; 
    }
