ASP.NET Mysql操作類

以下連接MySql數據庫以VS2010為例，對于其他的編輯器也差不多

1. 我們需要在Mysql官網下載一個組件http://dev.mysql.com/downloads/connector/net/? 下載最新版的即可，并且安裝connector，其實僅僅只是為了得到Mysql.Data.dll ( 0.0 )

2. 在你的VS2010 解決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 plain?copy

<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. 在你的代碼前面添加using MySQL.Data.MySqlClient;

下面是個簡單的連接Mysql 并且使用的例子

[csharp]?view plain?copy

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();??

}??

}??

}??

Mysql官方.net連接文檔：

I'm using Visual Web Developer 2010 Express Edition (and Visual C# 2010 Express) with MySQL. This is what I did:

1 - Download and install MySQL connector(just to get MySql.Data.dll).

2 - VWD 2010 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();
}
}
