Posted 2020-08-10

1.更新程序包EntityFramework->6.1.3

2.下载程序包mysql.Data.Entities（Ver:6.8.3）

3.修改config.cs或者web.config，包含以下内容

<configuration>

<configSections>
<connectionStrings>
<add name="MyDb" connectionString="Data Source=数据库服务器地址;Initial Catalog=数据库名称;user id=root;password=密码;" providerName="MySql.Data.MySqlClient" />
</connectionStrings>

<entityFramework>
<providers>
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" />
</providers>
</entityFramework>

 

4.创建类

public class AppLog
{
public long AppLogId { get; set; }
public DateTime Dt{get;set;}
public int Level { get; set; }
public string Source { get; set; }
public string MessageText { get; set; }
}

[DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))]
public class AppDbContext : DbContext
{

public DbSet<AppLog> AppLogs { get; set; }
public AppDbContext()
: base("name=MyDb")
{

}

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{

base.OnModelCreating(modelBuilder);

}

}

AutomaticMigrationsEnabled = true;
