使用LINQ检查数据库中是否存在表

using System;
using System.Linq;
using System.Data.Entity;

public class MyContext : DbContext
{
    public MyContext() : base("name=MyConnectionString") { }
    public DbSet<Table> Tables { get; set; }
}

public class Table
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class Program
{
    public static void Main()
    {
        using (var context = new MyContext())
        {
            if (context.Tables.Any(t => t.Name == "MyTable"))
            {
                Console.WriteLine("Table exists!");
            }
            else
            {
                Console.WriteLine("Table does not exist.");
            }
        }
    }
}
