我正在尝试在我的 c# .Net 应用程序中连接到 MySQL 数据库
当我尝试连接时收到此错误:不支持关键字:“端口”。
该错误似乎表明我的连接字符串存在问题
<add name="mydataEntities" connectionString="server=myserver.com;port=3306;password=xxxx;user id=yyyy;database= mydatabase;persistsecurityinfo=True" providerName="MySql.Data.MySqlClient" />
我添加了参考:
MySql.Data 6.9.7.0(适用于 MySQL 的 ADO.Net 驱动程序)
和 MySql.Data.Entity.EF6 6.9.7.0(支持实体框架 6.0)
在我的配置中我有:
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="mssqllocaldb" />
</parameters>
</defaultConnectionFactory>
<providers>
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Culture=neutral, PublicKeyToken=c5687fc88969c44d">
</provider>
</providers>
</entityFramework>
<dependentAssembly>
<assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.9.7.0" newVersion="6.9.7.0" />
</dependentAssembly>
<system.data>
<DbProviderFactories>
<remove invariant="MySql.Data.MySqlClient" />
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.7.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>
连接字符串在这里设置:
public class Repository
{
protected mydataEntities DbContext;
public Repository()
{
DbContext = new mydataEntities (ConfigurationManager.ConnectionStrings["mydataEntities"].ConnectionString);
}
}
我注意到堆栈跟踪似乎正在使用 System.Data.SqlClient 提供程序,如下所示:
我已经删除了 MySql.Data 和 MySql.Data.Entity.EF6 引用,清理解决方案,添加回引用然后重建......
谁能帮我找出这个错误的根源?
为什么 MySQL 连接器不使用我的配置中指定的providerName: MySql.Data.MySqlClient。
