C# 連接數據庫的配置方法

寫在前面

在項目的開發過程中我門常常遇到會忘記數據庫連接的配置的寫法的尷尬處境。俗話說，好記性不如爛筆頭。所以，mark一下。

1.Sqlserver數據庫連接

---

<connectionStrings>
<add name="Conn" connectionString="Provider=MSDAORA;Data Source=demo;User ID=sa;Password=123456;" providerName="System.Data.OracleClient"/>
</connectionStrings>

2.Oracle數據庫連接

---

<connectionStrings>
<add name="Conn" connectionString="server=.;database=demo;uid=sa;pwd=123456" providerName="System.Data.SqlClient"/>
</connectionStrings>

3.MySql數據庫連接

---

<connectionStrings>
<add name="Conn" connectionString="host=127.0.0.1;Port=3306;Database=mysql;uid=sa;pwd=12346" providerName="MySql.Data.MySqlClient"/>
</connectionStrings>

4.Acces數據庫連接

---

<connectionStrings>
<add name="Conn" connectionString="Provider=Microsoft.Jet.OLEDB.4.0; Data Source={0}App_Data/demo.mdb" providerName="System.Data.OleDb"/>
</connectionStrings>

5.SQLite數據庫連接

---

<connectionStrings>
<add name="Conn" connectionString="host=127.0.0.1;Port=3306;Database=mysql;uid=sa;pwd=12346" providerName="MySql.Data.MySqlClient"/>
</connectionStrings>
