EF6 自定义迁移表名

Posted 2020-10-18 OMI天空

在下列代码片段中已经EF6迁移表的表名更改为

MigrationHistory
注意：下代码片段建议和DbContext同程序集

 1    public class ModelConfiguration : DbConfiguration
 2     {
 3         public ModelConfiguration()
 4         {
 5 
 6             var conn = System.Configuration.ConfigurationManager.ConnectionStrings[ConnectionConst.DefaultConnectionKey];
 7             var connProvder = conn.ProviderName;
 8 
 9             this.SetHistoryContext(connProvder, (connection, defaultSchema) => new MigrationContext(connection, defaultSchema));
10         }
11     }

 1  /// <summary>
 2     /// 迁移表
 3     /// </summary>
 4     public class MigrationContext : HistoryContext
 5     {
 6         public MigrationContext(DbConnection dbConnection, string defaultSchema)
 7             : base(dbConnection, defaultSchema)
 8         {
 9         }
10 
11         protected override void OnModelCreating(DbModelBuilder modelBuilder)
12         {
13             base.OnModelCreating(modelBuilder);
14             modelBuilder.Entity<HistoryRow>().ToTable(tableName: "MigrationHistory");
15         }
16     }

1   public class ConnectionConst
2     {
3         /// <summary>
4         /// 数据库连接默认字符串
5         /// </summary>
6         public const string DefaultConnectionKey = "DefaultConnection";
7     }
