我正在尝试使用vs2010中的c#连接到mysql。我从mysql站点安装了6.3.5版本的.net连接器。我尝试使用以下连接字符串 -

<add name="mySql" connectionString="Server=localhost;Database=mydb;Uid=User;Pwd=mypass;" providerName="System.Data.OleDb.OleDbConnection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

我收到以下错误 -

An OLE DB Provider was not specified in the ConnectionString.  An example would be, 'Provider=SQLOLEDB;'.

然后我将连接字符串更改为 -

<add name="mySqlTarget" connectionString="Provider=MySQLProv;Server=localhost;Database=mydb;Uid=User;Pwd=mypass;" providerName="System.Data.OleDb.OleDbConnection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

并收到以下错误 -

The 'MySQLProv' provider is not registered on the local machine.

有谁知道为什么会这样?

感谢您的任何想法。

看看http://www.connectionstrings.com/mysql。但是,您不应该通过OLEDB提供商。尝试类似:

<add name="mySql"
     connectionString="Server=localhost;Database=mydb;Uid=User;Pwd=mypass;" 
     providerName="MySql.Data.MySqlClient"/>
