ArcGIS version not specified. You must call RuntimeManager.Bind before creating any ArcGIS component

问题：ArcGIS version not specified. You must call RuntimeManager.Bind before creating any ArcGIS components.

解决方案：

1、拖动工具箱中的LicenseControl控件到窗体

2、在程序主入口中（program.cs）添加代码，添加后如下：

namespace WindowsApplication001
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
    }
}
