C# 链接MySql数据库只得注意的几点:
1、C#链接MySql数据库要在网上下载一个mysql-connector-net-6.0.4-noinstall.rar 这里面放的都是一堆dll .将他们全部放在ProjectBin 然后在VS里引入一下就OK啦~ 对了mysql.data.cf.dll这个除外(不要引用)
2、进行数据库链接的时候注意了,c#链接MySql是和链接SQl的代码是不一样的。
c#链接MySql是这样的:
string MySqlString = "User Id=a;pwd=a;Host=服务器;Port=服务器端口号;Database=数据库;Character Set=utf8";
下面试个实例:
using MySql.Data.MySqlClient;
namespace Discuz
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
this.Bind();
}
}
public void Bind()
{
string MySqlString = "User Id=dis;pwd=sa;Host=1.2.3.4;Port=6033;Database=dis;Character Set=utf8";
MySqlConnection conn = new MySqlConnection(MySqlString);
conn.Open();
string bb = "SELECT p.author, p.message FROM cdb_threads AS t INNER JOIN cdb_posts AS p ON t.tid = p.tid where t.fid = 34 and digest !=0";
MySqlDataAdapter sda = new MySqlDataAdapter(bb, conn);
DataSet ds = new DataSet();
sda.Fill(ds, "T");
this.GridView1.DataSource = ds;
this.GridView1.DataBind();
conn.close();
}
}
}
