C#+ArcEngine代碼檢測ArcEngine是否安裝以及是否授權

檢測ArcEngine Runtime是否安裝的代碼

       private void CheckInStallAERuntime()
        {

            //通過查詢系統註冊表檢測是否安裝
            Microsoft.Win32.RegistryKey LocalMachineRegKey = Microsoft.Win32.Registry.LocalMachine;
            Microsoft.Win32.RegistryKey InstallDirRegKey = LocalMachineRegKey.OpenSubKey(@"SOFTWARE\ESRI\Engine10.0\CoreRuntime");

            if (InstallDirRegKey == null)
            {
                MessageBox.Show("沒有安裝ArcGIS Runtime！");
            }
            else
            {
                string InstallDirStr = InstallDirRegKey.GetValue("InstallDir").ToString();
                MessageBox.Show("ArcGIS Runtime安裝目錄：" + InstallDirStr);
            }
        }

檢測ArcEngine Runtime是否授權的代碼

        private bool CheckLicenseProduct()
        {
            //Check out a Spatial Analyst license with the ArcView product.
            esriLicenseProductCode productCode = esriLicenseProductCode.esriLicenseProductCodeEngine;

            IAoInitialize pAoInitialize = new AoInitializeClass();
            esriLicenseStatus licenseStatus = esriLicenseStatus.esriLicenseUnavailable;
            //Check the productCode.
            licenseStatus = pAoInitialize.IsProductCodeAvailable(productCode);
            if (licenseStatus == esriLicenseStatus.esriLicenseAvailable)
            {
                pAoInitialize = null;
                return true;
            }
            return false;       
        }

在判斷runtime是否授權之前必須進行許可綁定，否則出錯
