本文實例講述了C#經由過程反射獲得以後工程中一切窗體並翻開的辦法。分享給年夜家供年夜家參考。詳細完成辦法以下:
using System; using System.Collections.Generic; using System.Linq; using System.Windows.Forms; namespace TestAppHelperMSDNSample { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Form startup = new Form(); startup.Text = "Choose a form to run"; startup.Size = new System.Drawing.Size(300, 300); startup.StartPosition = FormStartPosition.CenterScreen; startup.Load += new EventHandler(startup_Load); ComboBox cboForms = new ComboBox(); cboForms.Name = "cboForms"; cboForms.DropDownStyle = ComboBoxStyle.DropDownList; cboForms.Size = new System.Drawing.Size(250, 20); cboForms.Location = new System.Drawing.Point(25, 75); startup.Controls.Add(cboForms); Button btnOpenForm = new Button(); btnOpenForm.Text = "Open Form"; btnOpenForm.Size = new System.Drawing.Size(100, 30); btnOpenForm.Location = new System.Drawing.Point(100, 150); btnOpenForm.Click += new EventHandler(btnOpenForm_Click); startup.Controls.Add(btnOpenForm); Application.Run(startup); } static void btnOpenForm_Click(object sender, EventArgs e) { ComboBox cbo = ((sender as Button).Parent as Form).Controls["cboForms"] as ComboBox; Properties.Settings.Default.LastFormFullName = cbo.SelectedItem.ToString(); Properties.Settings.Default.Save(); Form f = Activator.CreateInstance(Type.GetType(cbo.SelectedItem.ToString())) as Form; f.ShowDialog(); } static void startup_Load(object sender, EventArgs e) { ComboBox cbo = ((sender as Form).Controls["cboForms"] as ComboBox); // load all the Forms in executing assembly Type[] types = System.Reflection.Assembly.GetExecutingAssembly().GetExportedTypes(); foreach (Type t in types) { if (t.BaseType == typeof(Form)) { cbo.Items.Add(t.FullName); } } // select the last used if (!string.IsNullOrEmpty(Properties.Settings.Default.LastFormFullName)) { if(cbo.Items.Contains(Properties.Settings.Default.LastFormFullName)) { int index = cbo.FindString(Properties.Settings.Default.LastFormFullName); if (index >= 0) cbo.SelectedIndex = index; } } } } }
願望本文所述對年夜家的C#法式設計有所贊助。
