Get All the Tables Name using LINQ

In this article you will learn how to get the names of all the tables using LINQ

We need to list the names of all the tables of the DataContext.

This is very simple using LINQ mapping.

1. Add the namespace


2. Get the model of the datacontext type.


DataClasses1DataContext is your datacontext class created by LINQ to SQL.

3. Use GetTables() method to list all the table names.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.Linq.Mapping;
 
namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            var datamodel = new AttributeMappingSource().GetModel(typeof(DataClasses1DataContext));
            foreach (var r in datamodel.GetTables())
            {
                Console.WriteLine(r.TableName);
            }
            Console.ReadKey(true);
        }
    }
}

Output


There is one more scenario. If you already have an instance of a DataContext and you want to list all the table names then you need to get the model as below:


Here context is instance of datacontext class.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.Linq.Mapping;

namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{

DataClasses1DataContext context = new DataClasses1DataContext();
var datamodel = context.Mapping;
foreach (var r in datamodel.GetTables())
{
Console.WriteLine(r.TableName);
}
Console.ReadKey(true);
}
}
}
