windowsForm 项目应该有个Program.cs文件,你这个没有。里面内容:
namespace WindowsFormsApplication1 { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } } }
