c# asp.net MySql.Data.DLL6.2下载,.net连接mysql数据库的第三方插件

解压后只需要把mysql.data.dll引入到项目里就可以用了

代码示例:

C#代码


using MySql.Data.MySqlClient;

protected void btn_login_Click(object sender, EventArgs e)
{
string mySqlCon = ConfigurationManager.ConnectionStrings["MySqlCon"].ConnectionString;

MySqlConnection myCon = new MySqlConnection(mySqlCon);

try
{
myCon.Open();

MySqlCommand selSql = new MySqlCommand("Select * From tt.table Where uname=@uname", myCon);

selSql.Parameters.Add("@uname", MySqlDbType.VarChar, 32).Value = this.txt_name.Text.Trim();

MySqlDataReader mydr = selSql.ExecuteReader();

while (mydr.Read())
{
if (mydr.HasRows)
{
Response.Write("<script type='text/javascript'>alert('" + mydr.GetString(0) + "') </script>");
}
}
myCon.Close();
mydr.Close();
}
catch (Exception ex)
{
Response.Write("<mce:script type='text/javascript'>alert(" + ex.ToString() + ")</mce:script>");
}
}

//<connectionStrings>
// <add name="MySqlCon" connectionString="Database=dbname;Data Source=127.0.0.1;User Id=root;Password=root;pooling=false;CharSet=utf8;port=3306" />
//</connectionStrings>
