C# MySql和实体框架代码优先
我首先遇到MySql和实体框架代码的问题 web.config.xml中的我的连接字符串C# MySql和实体框架代码优先,c#,mysql,frameworks,entity,C#,Mysql,Frameworks,Entity,我首先遇到MySql和实体框架代码的问题 web.config.xml中的我的连接字符串 <add name="EntityContext" connectionString="Server=127.0.0.1; port=8080 Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" /> 我的控制器 public EntityContext db = new EntityCont
<add name="EntityContext" connectionString="Server=127.0.0.1; port=8080 Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />
我的控制器
public EntityContext db = new EntityContext();
public ActionResult Index()
{
List<Pessoa> pessoas = db.Pessoas.ToList(); // here is the error
return View(pessoas);
}
public EntityContext db=new EntityContext();
公共行动结果索引()
{
List pessoas=db.pessoas.ToList();//下面是错误
返回视图(pessoas);
}
所以,当我按下F5键时,我得到了这样的信息:“输入字符串的格式不正确”
我想念什么
更新

将所有评论收集到答案中 在端口=3306后添加分号;并检查您的mysql侦听端口(可能是3306,mysql默认值?)。生成的连接字符串:
<add name="EntityContext" connectionString="Server=127.0.0.1; port=3306; Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />
MySql默认端口为3306;所以这里不用提这个 例如:
哪一行是异常?您忘记在端口=8080否后添加分号了?@Andreyvolshin,请给我一个例子。@DStanley,异常在这里:db.Pessoas.ToList()请同时发布堆栈跟踪。端口是默认值。没有必要把
public EntityContext db = new EntityContext();
public ActionResult Index()
{
List<Pessoa> pessoas = db.Pessoas.ToList(); // here is the error
return View(pessoas);
}
<add name="EntityContext" connectionString="Server=127.0.0.1; port=3306; Database=simple_crud; Uid=root; Pwd=;" providerName="MySql.Data.MySqlClient" />
<add name="DefaultConnection" providerName="MySql.Data.MySqlClient" connectionString="SERVER=localhost;DATABASE=testdb;UID=test;PASSWORD=test123;" />
