2，操作

public class WCHSOFTDbContext : AbpZeroDbContext<Tenant, Role, User, WCHSOFTDbContext>
{
　　public WCHSOFTDbContext(DbContextOptions<WCHSOFTDbContext> options)
   　　: base(options)
   {
   }
   protected override void OnModelCreating(ModelBuilder modelBuilder)
   {
   　　modelBuilder.ChangeAbpTablePrefix<Tenant, Role, User>("Wch");
   　　base.OnModelCreating(modelBuilder);
   }
}

3，效果

4，後記

　　本人最近正在研究Abp框架，發現官方給的demo和文檔只是交大家怎麽使用，有些功能文檔中並沒有寫明，所以必須通過查看源碼來找到自己問題的解決方法。大家在abp開發中有什麽遇到的問題或者有什麽建議，歡迎大家留言。
