Web user control member variable not accessible when not declared static

[owlisen]

I am creating a web user control using C# to play some .wav files in the server. Following is my code.\[code\]public partial class WaveFilePlayer : System.Web.UI.UserControl{ //private string[] files; private static string[] files; protected void ButtonLoad_Click(object sender, EventArgs e) { string resourcePath = ConfigurationManager.AppSettings["ResourcePath"]; string searchPattern = ConfigurationManager.AppSettings["SearchPattern"]; files = System.IO.Directory.GetFiles(path, searchPattern); } protected void ButtonPlay_Click(object sender, EventArgs e) { int selectedIndex = ListBoxFiles.SelectedIndex; SoundPlayer soundPlayer = new SoundPlayer(files[selectedIndex]); soundPlayer.Play(); }\[/code\]As seen in the code above I declare \[code\]string[] files\[/code\] as a member variable. Then I assign it in the \[code\]ButtonLoad_Click\[/code\] method. But it is impossible to access it in the \[code\]ButtonPlay_Click\[/code\] method unless \[code\]string[] files\[/code\] is declared static.Does it mean that a new object of \[code\]System.Web.UI.UserControl\[/code\] is not created while loading the user control in a asp.net page? And does it mean that when multiple clients (browsers) try to play the .wav files, only one instance of the \[code\]string[] files\[/code\] is created at the server to be used by all clients?
