Using sqlite with .NET
The other day I found that there is a .NET wrapper for sqlite. sqlite is a very cool embeddable SQL-92 database engine. It's a single library that gives you a very fast, very scalable (2TB), single file, multi-user database. I thought the .NET wrapper is exceptionally handy because ADO is slow, and is hard to use (compared to this) and a HUGE overkill for smaller apps. It lets smaller apps have a real relational database without huge numbers of dependencies, complicated installs, or the complexity of ADO. Here is a really quick example program I wrote to try it out:
using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using SQLite.NET; namespace WindowsApplication2 { /// <summary> /// Summary description for Form1. /// </summary> public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.ListBox listBox1; private System.ComponentModel.Container components = null; private System.Windows.Forms.TextBox textBox1; private System.Windows.Forms.Button button1; private SQLiteClient db; public Form1() { db = new SQLiteClient("test.db"); InitializeComponent(); UpdateList(); } public void UpdateList() { SQLiteResultSet results; results = db.Execute("select name, phone from people order by name;"); listBox1.Items.Clear(); foreach(ArrayList row in results.Rows) { listBox1.Items.Add(row[0]); } } protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.listBox1 = new System.Windows.Forms.ListBox(); this.textBox1 = new System.Windows.Forms.TextBox(); this.button1 = new System.Windows.Forms.Button(); this.SuspendLayout(); // // listBox1 // this.listBox1.Location = new System.Drawing.Point(8, 8); this.listBox1.Name = "listBox1"; this.listBox1.Size = new System.Drawing.Size(136, 199); this.listBox1.TabIndex = 0; // // textBox1 // this.textBox1.Location = new System.Drawing.Point(192, 24); this.textBox1.Name = "textBox1"; this.textBox1.Size = new System.Drawing.Size(120, 20); this.textBox1.TabIndex = 1; this.textBox1.Text = "textBox1"; // // button1 // this.button1.Location = new System.Drawing.Point(320, 24); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(72, 16); this.button1.TabIndex = 2; this.button1.Text = "button1"; this.button1.Click += new System.EventHandler(this.button1_Click); // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(408, 349); this.Controls.Add(this.button1); this.Controls.Add(this.textBox1); this.Controls.Add(this.listBox1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false); } #endregion /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.Run(new Form1()); } private void button1_Click(object sender, System.EventArgs e) { db.Execute("insert into people values ('" + textBox1.Text.Replace("'","''") + "','111');"); UpdateList(); } } } http://jclement.ca/devel/dotnet/sqlite.html
