Below code can be used for copying combobox items in an array.
Code:string[] strArray = new string[comboBox1.Items.Count]; for (int i = 0; i < comboBox1.Items.Count; i++) { strArray[i] = comboBox1.Items[i].ToString(); }Leave a comment:

SystemState.Con nectionsDesktop Count already returns an integer value, so it is useless to call Convert.ToInt32 ()
In case when return-type is not known, use TryParse() method.
TryParse() returns bool value.
Code:int desktopCount = 0; if(Int32.TryParse(SystemState.ConnectionsDesktopCount, out desktopCount)) { //true } else { //false }Leave a comment:

There is an error in the value of your Filter property.
No need to use + operator and , comma is missing.
It should be like,
Code:OpenFileDialog.Filter = "xml files (*.xml) |*.xml, *.xsl";
To get selected file in textbox,
Code:Textbox.Text = OpenFileDialog.Filename;
