Simplemente necesitamos llamar una librería que se llama
SystemInformation, se encuentra en System.Windows.Forms.SystemInformation
La cual tiene algunas funcionalidades, aquí algunos ejemplos de uso:
using System; using System.Collections; using System.ComponentModel; using System.Drawing; using System.Reflection; using System.Windows.Forms; namespace SystemInfoBrowser { public class SystemInfoBrowserForm : System.Windows.Forms.Form { private System.Windows.Forms.ListBox listBox1; private System.Windows.Forms.TextBox textBox1; public SystemInfoBrowserForm() { this.SuspendLayout(); InitForm(); // Add each property of the SystemInformation class to the list box. Type t = typeof(System.Windows.Forms.SystemInformation); PropertyInfo[] pi = t.GetProperties(); for( int i=0; i<pi.Length; i++ ) listBox1.Items.Add( pi[i].Name ); textBox1.Text = "The SystemInformation class has "+pi.Length.ToString()+"properties.\r\n"; // Configure the list item selected handler for the list box to invoke a // method that displays the value of each property. listBox1.SelectedIndexChanged += new EventHandler(listBox1_SelectedIndexChanged); this.ResumeLayout(false); } private void listBox1_SelectedIndexChanged(object sender, EventArgs e) { // Return if no list item is selected. if( listBox1.SelectedIndex == -1 ) return; // Get the property name from the list item. string propname = listBox1.Text; if( propname == "PowerStatus" ) { // Cycle and display the values of each property of the PowerStatus property. textBox1.Text += "\r\nThe value of the PowerStatus property is:"; Type t = typeof(System.Windows.Forms.PowerStatus); PropertyInfo[] pi = t.GetProperties(); for( int i=0; i<pi.Length; i++ ) { object propval = pi[i].GetValue(SystemInformation.PowerStatus, null); textBox1.Text += "\r\n PowerStatus."+pi[i].Name+" is: "+propval.ToString(); } } else { // Display the value of the selected property of the SystemInformation type. Type t = typeof(System.Windows.Forms.SystemInformation); PropertyInfo[] pi = t.GetProperties(); PropertyInfo prop = null; for( int i=0; i<pi.Length; i++ ) if( pi[i].Name == propname ) { prop = pi[i]; break; } object propval = prop.GetValue(null, null); textBox1.Text += "\r\nThe value of the "+propname+" property is: "+propval.ToString(); } } private void InitForm() { // Initialize the form settings this.listBox1 = new System.Windows.Forms.ListBox(); this.textBox1 = new System.Windows.Forms.TextBox(); this.listBox1.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right))); this.listBox1.Location = new System.Drawing.Point(8, 16); this.listBox1.Size = new System.Drawing.Size(172, 496); this.listBox1.TabIndex = 0; this.textBox1.Anchor = ((System.Windows.Forms.AnchorStyles)(((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Right))); this.textBox1.Location = new System.Drawing.Point(188, 16); this.textBox1.Multiline = true; this.textBox1.ScrollBars = System.Windows.Forms.ScrollBars.Vertical; this.textBox1.Size = new System.Drawing.Size(420, 496); this.textBox1.TabIndex = 1; this.ClientSize = new System.Drawing.Size(616, 525); this.Controls.Add(this.textBox1); this.Controls.Add(this.listBox1); this.Text = "Select a SystemInformation property to get the value of"; } [STAThread] static void Main() { Application.Run(new SystemInfoBrowserForm()); } } }
