C＃ - 搜索跨越多個列

Question

兩個問題：

1. 你會如何合併代碼的兩位？似乎有點多餘，讓他們作爲兩個大塊！

2. 你將如何去搜索多個列（並返回結果，如果它在以下任何列中找到：名稱，性別，年齡）？

   private void button1_Click(object sender, EventArgs e) 
   { 
        BindingSource bs = new BindingSource(); 
        bs.DataSource = dataGridView1.DataSource; 
        bs.Filter = "id like '%" + textBox1.Text + "%'"; 
        dataGridView1.DataSource = bs; 
   } 
   
   private void textBox1_TextChanged(object sender, EventArgs e) 
   { 
        BindingSource bs = new BindingSource(); 
        bs.DataSource = dataGridView1.DataSource; 
        bs.Filter = "id like '%" + textBox1.Text + "%'"; 
        dataGridView1.DataSource = bs; 
   } 
   

Answer 1

回答你的第一個問題：

創建功能，讓你的搜索語句，並調用它，只要你required.as如下：

 private void button1_Click(object sender, EventArgs e) 
     { 
      SearchData(); 
     } 

     private void textBox1_TextChanged(object sender, EventArgs e) 
     { 
      SearchData(); 
     } 
     private void SearchData() 
     { 
      BindingSource bs = new BindingSource(); 
      bs.DataSource = dataGridView1.DataSource; 
      bs.Filter = "id like '%" + textBox1.Text + "%'"; 
      dataGridView1.DataSource = bs; 
     } 

回答到你的第二個問題：

你可以寫如下篩選：

bs.Filter = "id like '%" + textBox1.Text + "%' and name like '%" + textBox2.Text + "%'";
