Mysql操作类
以下连接MySql数据库以VS为例，对于其他的编辑器也差不多
1. 我们需要在Mysql官网下载一个组件/downloads/connector/net/ 下载最新版的即可，并且安装connector，其实仅仅只是为了得到Mysql.Data.dll ( 0.0 )
2. 在你的VS 解决方案管理器里面添加 Mysql.Data.dll 引用(通常在c:\program files\MySQL\MySQL Connector Net(your version here)\Assemblies\v4.0 or v2.0)
3. 在你的web.config里面添加connection:
[csharp]view plaincopy <connectionStrings><addname="MySQLConnString"connectionString="Server=your_MySql_Server_IP;Port=3306;Database=databaseName;Uid=username;Pwd=yourpassword;pooling=false;"providerName="MySql.Data.MySqlClient"/></connectionStrings>
4. 在你的代码前面添加using MySQL.Data.MySqlClient;
下面是个简单的连接Mysql 并且使用的例子
[csharp]view plaincopy protectedvoidPage_Load(objectsender,EventArgse){DataSetds_temp=GetObjects();ListBox1.DataSource=ds_temp;ListBox1.DataTextField="yourColumn";ListBox1.DataValueField="yourColumn";ListBox1.DataBind();}protectedstaticDataSetGetObjects(){DataSetds_temp=Connection_cls.GetDataSetQuery("SELECTyourColumnFROMyourtable",null);returnds_temp;}privatestaticstringgetHostString(){stringhost=ConfigurationManager.ConnectionStrings["MySQLConnString"].ConnectionString;returnhost;}publicstaticDataSetGetDataSetQuery(stringsql,ArrayListparamList){using(MySqlConnectionconn=newMySqlConnection(getHostString())){try{conn.Open();MySqlDataAdapterda=newMySqlDataAdapter(sql,conn);da.SelectCommand.Parameters.Clear();if(paramList!=null){for(inti=0;i<paramList.Count;i++){da.SelectCommand.Parameters.Add(paramList[i]asMySqlParameter);}}DataSetds=newDataSet();da.Fill(ds);returnds;}finally{conn.Close();}}}
Mysql官方.net连接文档：
I'm using Visual Web Developer Express Edition (and Visual C# Express) with MySQL. This is what I did:
1 - Download and install MySQL connector(just to get MySql.Data.dll).
2 - VWD in the Solution Explorer add reference to MySql.Data.dll(usually in c:\program files\MySQL\MySQL Connector Net(your version here)\Assemblies\v4.0 or v2.0)
3 - In the web.config add your string connection:
<connectionStrings>
<add name="MySQLConnString" connectionString="Server=your_MySql_Server_IP;Port=3306;Database=databaseName;Uid=username;Pwd=yourpassword;pooling=false;" providerName="MySql.Data.MySqlClient"/>
</connectionStrings>
4 - In the code behind type in: "using MySQL.Data.MySqlClient;"
Now you can use it as in this example:
protected void Page_Load(object sender, EventArgs e)
{
DataSet ds_temp = GetObjects();
ListBox1.DataSource = ds_temp;
ListBox1.DataTextField = "yourColumn";
ListBox1.DataValueField = "yourColumn";
ListBox1.DataBind();
}
protected static DataSet GetObjects()
{
DataSet ds_temp = Connection_cls.GetDataSetQuery("SELECT yourColumn FROM yourtable", null);
return ds_temp;
}
private static string getHostString()
{
string host = ConfigurationManager.ConnectionStrings["MySQLConnString"].ConnectionString;
return host;
}
public static DataSet GetDataSetQuery(string sql, ArrayList paramList)
{
using (MySqlConnection conn = new MySqlConnection(getHostString()))
{
try
{
conn.Open();
MySqlDataAdapter da = new MySqlDataAdapter(sql, conn);
da.SelectCommand.Parameters.Clear();
if (paramList != null)
{
for (int i = 0; i < paramList.Count; i++)
{
da.SelectCommand.Parameters.Add(paramList[i] as MySqlParameter);
}
}
DataSet ds = new DataSet();
da.Fill(ds);
return ds;
}
finally
{
conn.Close();
}
}
}
