C#中MySQL函数用DATASET 和 MySqlDataAdapter 操作数据库

String connStr, commStr;
DataSet ds;       //数据集
BindingSource bs;  //数据绑定源，注意是全局的变量
MySQLConnection myconn;
MySQLDataAdapter myadp;//数据适配器

connStr = "Data Source=myshiyandb;Password=110810;User ID=root;Location=localhost;Port=3306;Extended Properties=";//数据库连接字符串
//myconn = new MySQLConnection(new MySQLConnectionString("localhost", "myshiyandb", "root", "110810").AsString);
myconn = new MySQLConnection(connStr);

try
{
myconn.Open();//打开数据库
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}
//
ds = new DataSet();
commStr = "select * from table1;";

myadp = new MySQLDataAdapter(commStr , myconn); //适配器
myadp.Fill(ds,"table"); //将查询到数据填充到数据集
bs = new BindingSource();
bs.DataSource = ds.Tables["table"];
dataGridView1.DataSource = bs; //绑定DataGridView到DataSet
//shut
try
{
myconn.Close();
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}

connStr = "Data Source=myshiyandb;Password=110810;User ID=root;Location=localhost;Port=3306;Extended Properties=";//数据库连接字符串
//myconn = new MySQLConnection(new MySQLConnectionString("localhost", "myshiyandb", "root", "110810").AsString);
myconn = new MySQLConnection(connStr);

try
{
myconn.Open();//打开数据库
}
catch (Exception e2)
{
MessageBox.Show(e2.Message);
}

string strInsert = null;
strInsert = " insert into " + "table1" + " values "
+ " ( "
+ "'" + tbxLuruName.Text + "'" + ", "
+ tbxLuruAge.Text
+ " ) ";
//---
commStr = strInsert;
MySQLCommand cmd = new MySQLCommand(commStr, myconn);
cmd.ExecuteNonQuery();
//myadp = new MySQLDataAdapter(commStr, myconn); //适配器

try
{
myconn.Close();
}
