在vs2010中 工具->数据库连接 里要想连接到mysql数据库，需要安装这样一个东西： MySql Connector；1.首先安装 connector 。下载地址：（http://www.mysql.com/downloads/connector/net/）2.现在就可以了，打开vs2010试试吧！

安装完成后找到安装目录下(C:\Program Files\MySQL\MySQL Connector Net 6.4.4\Assemblies\v4.0\MySql.Data.dll,添加引用到工程中.

现在一切就OK了！

如果想在工程c#中连接mysql，需如下code:

//define the connection reference and initialize it

 MySql.Data.MySqlClient.MySqlConnection msqlConnection = null;

 msqlConnection = new MySql.Data.MySqlClient.MySqlConnection(“server=localhost;user id=UserName;Password=UserPassword;database=DatabaseName;persist security info=False”);

 //define the command reference

 MySql.Data.MySqlClient.MySqlCommand msqlCommand = new MySql.Data.MySqlClient.MySqlCommand();

 //define the connection used by the command object

 msqlCommand.Connection = this.msqlConnection;

 //define the command text

 msqlCommand.CommandText = "SELECT * FROM TestTable;";

 try

{

 //open the connection

 this.msqlConnection.Open();

 //use a DataReader to process each record

 MySql.Data.MySqlClient.MySqlDataReader msqlReader = msqlCommand.ExecuteReader();

 while (msqlReader.Read())

 {

 //do something with each record

 }

}

catch (Exception er)

{

 //do something with the exception

}

finally

{

 //always close the connection

 this.msqlConnection.Close();

}
