c#通路各資料庫的providerName各驅動

如果為Mysql 資料庫--->providerName="MySql.Data.MySqlClient"（沒裝mysql dotnet 安裝版的話就得在C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG中machine.config加語句了）

在machine.config檔案中有這麼一段，如果沒有name="MySQL Data Provider" 則會出現這種錯誤。

<system.data>

    <DbProviderFactories>

      <add name="Odbc Data Provider" invariant="System.Data.Odbc" description=".Net Framework Data Provider for Odbc" type="System.Data.Odbc.OdbcFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

    </DbProviderFactories>

</system.data>

如果為Aceess資料庫--->providerName="System.Data.OleDb"

如果為Oracle 資料庫--->providerName="System.Data.OracleClient"或者providerName="Oracle.DataAccess.Client"

如果為SQLite資料庫--->providerName="System.Data.SQLite"

如果為sql     資料庫--->providerName="System.Data.SqlClient"
