前面有說明使用EF動態新建資料庫與表，資料庫使用的是SQL SERVER2008的，在使用MYSQL的時候還是有所不同
一、添加 EntityFramework.dll ，System.Data.Entity.dll ，MySql.Data, MySql.Data.Entity.EF6
註意：Entity Framework5.0.0(好像最新的6.X是不支持mysql的)
二、添加dll文件，可以使用“管理NuGet程式包”或者“Nuget程式包管理控制台”添加
與 控制台平臺添加
以下為控制台平臺安裝dll語句
EntityFramework.dll ： Install-Package EntityFramework -Version 5.0.0
MySql.Data ： Install-Package MySql.Data -Version 6.9.12
MySql.Data.Entity：Install-Package MySql.Data.Entity -Version 6.9.12
三、在app.config文件中添加connectionStrings
源文件
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
</configSections>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.9.12.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
</providers>
</entityFramework>
<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=6.9.12.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>
<connectionStrings>
<!--<add name="conncodefirst" connectionString="server=127.0.0.1;port=3306;uid=root;pwd=repower;database=code" providerName="MySql.Data.MySqlClient"/>-->
<add name="conncodefirst" connectionString="server=127.0.0.1;user id=root;password=repower;database=code" providerName="MySql.Data.MySqlClient" />
</connectionStrings>
</configuration>
四、添加類
[Table("Student")]
public class Student
{
public Student()
{
}
[Key]
public int StudentID { get; set; }
public string StudentName { get; set; }
public DateTime AddTime { get; set; }
}
[Table("Standard")]
public class Standard
{
public Standard()
{
}
public int StandardId { get; set; }
public string StandardName { get; set; }
public DateTime AddTime { get; set; }
}
添加SchoolContext 繼承DbContext
[DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))]
public class SchoolContext : DbContext
{
public SchoolContext()
: base("name=conncodefirst")
{
}
static SchoolContext()
{
DbConfiguration.SetConfiguration(new MySql.Data.Entity.MySqlEFConfiguration());
}
public DbSet<Student> Students { get; set; }
public DbSet<Standard> Standards { get; set; }
//protected override void OnModelCreating(DbModelBuilder modelBuilder)
//{
// base.OnModelCreating(modelBuilder);
//}
}
最後調用
SchoolContext dbCOntext = new SchoolContext();
//dbCOntext.Database.
bool flag = dbCOntext.Database.CreateIfNotExists();
Student stud = new Student() { StudentName = "New Student", AddTime = DateTime.Now };
dbCOntext.Students.Add(stud);
dbCOntext.SaveChanges();
結果
