After my last post, I got a question asking how to list all the Column names of a given table using LINQ.
Before going through this post, I recommend you to read Get All the Tables Name using LINQ
Let us say, you have a table called dbo.Person and you need to find all the columns of this particular table.
So first we need to find whether table exists in DataContext or not
Dbo.Person is name of the table.
We are looking through all the tables and finding where given table exists or not. Once we get table we need to list the entire columns name
Full source code is as below. In below code we are finding whether dbo.Person table is existing or not. If existing in DataContext then listing all the columns name
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())
{
if (r.TableName.Equals("dbo.Person", StringComparison.InvariantCultureIgnoreCase))
{
foreach (var r1 in r.RowType.DataMembers)
{
Console.WriteLine(r1.MappedName);
}
}
}
Console.ReadKey(true);
}
}
}
Output
