How to execute an .SQL script file using c#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;
using System.IO;
using System.Data.SqlClient;

public partial class ExcuteScript : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string sqlConnectionString = @"Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=ccwebgrity;Data Source=SURAJIT\SQLEXPRESS";

        string script = File.ReadAllText(@"E:\Project Docs\MX462-PD\MX756_ModMappings1.sql");

        SqlConnection conn = new SqlConnection(sqlConnectionString);

        Server server = new Server(new ServerConnection(conn));

        server.ConnectionContext.ExecuteNonQuery(script);
    }
}

I tried this solution with Microsoft.SqlServer.Management but it didn't work well with .NET 4.0 so I wrote another solution using .NET libs framework only.

string script = File.ReadAllText(@"E:\someSqlScript.sql");

// split script on GO command
IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$", RegexOptions.Multiline | RegexOptions.IgnoreCase);

Connection.Open();
foreach (string commandString in commandStrings)
{
    if (!string.IsNullOrWhiteSpace(commandString.Trim()))
    {
        using(var command = new SqlCommand(commandString, Connection))
        {
            command.ExecuteNonQuery();
        }
    }
}     
Connection.Close();

This Works on Framework 4.0 or Higher. Supports "GO". Also show the error message, line, and sql command.

using System.Data.SqlClient;

        private bool runSqlScriptFile(string pathStoreProceduresFile, string connectionString)
    {
        try
        {
            string script = File.ReadAllText(pathStoreProceduresFile);

            // split script on GO command
            System.Collections.Generic.IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$",
                                     RegexOptions.Multiline | RegexOptions.IgnoreCase);
            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                connection.Open();
                foreach (string commandString in commandStrings)
                {
                    if (commandString.Trim() != "")
                    {
                        using (var command = new SqlCommand(commandString, connection))
                        {
                        try
                        {
                            command.ExecuteNonQuery();
                        }
                        catch (SqlException ex)
                        {
                            string spError = commandString.Length > 100 ? commandString.Substring(0, 100) + " ...\n..." : commandString;
                            MessageBox.Show(string.Format("Please check the SqlServer script.\nFile: {0} \nLine: {1} \nError: {2} \nSQL Command: \n{3}", pathStoreProceduresFile, ex.LineNumber, ex.Message, spError), "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                            return false;
                        }
                    }
                    }
                }
                connection.Close();
            }
        return true;
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message, "Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            return false;
        }
    }
