How to read SQL Table data into a C# DataTable

Question

I've read a lot of posts about inserting a DataTable into a SQL table, but how can I pull a SQL table into a C#/.NET DataTable?

Answer 1

Here, give this a shot (this is just a pseudocode)

using System;
using System.Data;
using System.Data.SqlClient;


public class PullDataTest
{
    // your data table
    private DataTable dataTable = new DataTable();

    // your method to pull data from database to datatable   
    public void PullData()
    {
        string connString = @"your connection string here";
        string query = "select * from table";

        SqlConnection conn = new SqlConnection(connString);        
        SqlCommand cmd = new SqlCommand(query, conn);
        conn.Open();

        // create data adapter
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        // this will query your database and return the result to your datatable
        da.Fill(dataTable);
        conn.Close();
        da.Dispose();
    }
}
