不支持MySQL关键字:C#应用程序中的"端口"错误

Question

我正在尝试连接到我的c#.Net应用程序中的MySQL数据库

我尝试连接时收到此错误:不支持关键字:'port'.

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" />

我有参考添加:MySql.Data 6.9.7.0(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:

我删除了MySql.Data和MySql.Data.Entity.EF6引用,清理解决方案,添加引用然后重建......

任何人都可以帮我弄清楚这个错误的来源吗？

为什么不使用我在配置中指定的providerName:MySql.Data.MySqlClient的MySQL连接器.

Answer 1

这是解决方案：

我从覆盖基础连接字符串的分部类中删除了以下代码。

public partial class mydataEntities
    {
        public mydataEntities(string connectionString) : base(connectionString) { }
    }

我仍然对解决方案感到困惑，但似乎使用此代码，连接试图使用 Mssql 数据提供程序而不是 MySql
