具有相同事件的文本框數組

Question

我正在使用c＃處理Windows窗體應用程序項目，並試圖使用相同的事件操作來創建TextBox數組。我的意思是需要N個文本框（N與用戶分配不同），而所有「TextBox_TextChanged」事件都是相同的。如果你能幫助我，我會很感激。

Answer 1

請試試這個。

private void frmMain_Load(object sender, EventArgs e) 
    { 
      int userPermittedCount = 4 // You can add user defined permission no : of text box count here; 
      int pointX = 30; 
      int pointY = 40; 

      for (int i = 0; i < userPermittedCount; i++) 
      { 
       TextBox txtBox = new TextBox(); 
       txtBox.Location = new Point(pointX, pointY); 
       this.Controls.Add(txtBox); 
       this.Show(); 
       pointY += 20; 
       txtBox.TextChanged += txtAdd_TextChanged; 
      } 
    } 

private void txtAdd_TextChanged(object sender, EventArgs e) 
{ 
}

查找下面

 TextBox t1 = new TextBox(); 
     TextBox t2 = new TextBox(); 
     TextBox t3 = new TextBox(); 
     TextBox t4 = new TextBox(); 
     TextBox t5 = new TextBox(); 
     TextBox t6 = new TextBox(); 

     private void Form1_Load(object sender, EventArgs e) 
     { 
      TextBox[] tBoxes = { t1, t2, t3, t4, t5, t6 }; 

      foreach (TextBox item in tBoxes) 
      { 
       item.TextChanged += text_Changed; 
      } 
     } 

     private void text_Changed(object sender, EventArgs e) 
     { 

     }
