How to Execute Large SQL Scripts with GO Commands in C#?

Use GO command to execute large SQL scripts

Question: How to execute a large SQL script containing GO commands in a C# program? SqlCommand.ExecuteNonQuery() does not recognize the GO statement.

Answer: Use SQL Server Management Objects (SMO) that recognizes the GO delimiter.

Sample code:

<code class="language-csharp">public static void Main()
{
    string scriptDirectory = "c:\temp\sqltest\";
    string sqlConnectionString = "Integrated Security=SSPI;" +
                                  "Persist Security Info=True;Initial Catalog=Northwind;Data Source=(local)";
    DirectoryInfo di = new DirectoryInfo(scriptDirectory);
    FileInfo[] rgFiles = di.GetFiles("*.sql");
    foreach (FileInfo fi in rgFiles)
    {
        FileInfo fileInfo = new FileInfo(fi.FullName);
        string script = fileInfo.OpenText().ReadToEnd();
        using (SqlConnection connection = new SqlConnection(sqlConnectionString))
        {
            Server server = new Server(new ServerConnection(connection));
            server.ConnectionContext.ExecuteNonQuery(script);
        }
    }
}</code>
