C＃win表格datagrid視圖顯示MySql表

Question

嗨，我試圖將MySql表數據加載到我的勝利形式的應用程序按鈕點擊datagridview，並不能讓它工作。我想我錯過了綁定源，但我很困惑。

一些幫助，將不勝感激。

private void button3_Click(object sender, EventArgs e) 
    { 
     string connStr = "Data Source=localhost;port=3306;Initial Catalog=bitdb;User Id=root;Password='';"; 
     string query = "Select * from Client"; 
     using (MySqlConnection conn = new MySqlConnection(connStr)) 
     { 
      using (MySqlDataAdapter adapter = new MySqlDataAdapter(query, conn)) 
      { 
       DataSet ds = new DataSet(); 
       adapter.Fill(ds); 
       dataGridView1.DataSource = ds.Tables[0]; 
      } 
     } 
    }

根據文檔，你應該使用一個BindingSource與DataGridView組件。更多信息here。

private void button3_Click(object sender, EventArgs e) 
    { 
     string connStr = "Data Source=localhost;port=3306;Initial Catalog=bitdb;User Id=root;Password='';"; 
     string query = "Select * from Client"; 
     using (MySqlConnection conn = new MySqlConnection(connStr)) 
     { 
      using (MySqlDataAdapter adapter = new MySqlDataAdapter(query, conn)) 
      { 
       DataSet ds = new DataSet(); 
       adapter.Fill(ds); 
       var bindingSource = new BindingSource(); 
       bindingSource.DataSource = ds.Tables[0]; 
       dataGridView1.DataSource = bindingSource; 
      } 
     } 
    } 

此外，任何錯誤信息都會有幫助。
