主要原因是沒有釋放AO資源

public class Form1 : System.Windows.Forms.Form
{
??? private ESRI.ArcGIS.esriSystem.IAoInitialize m_AoInitialize = new ESRI.ArcGIS.esriSystem.AoInitializeClass();

?

??? private void Form1_Load(object sender, System.EventArgs e)
??? {
??????? // 創建新的AoInitialize對象
??????? if ( m_AoInitialize == null)
??????? {
??????????? System.Windows.Forms.MessageBox.Show("初始化失敗，程序不能運行！");
??????????? this.Close();
??????? }
??????? // 判斷產品是否有效
??????? ESRI.ArcGIS.esriSystem.esriLicenseStatus licenseStatus = (esriLicenseStatus)
??????????? m_AoInitialize.IsProductCodeAvailable(
??????????? ESRI.ArcGIS.esriSystem.esriLicenseProductCode.esriLicenseProductCodeEngine);
??????? if (licenseStatus == ESRI.ArcGIS.esriSystem.esriLicenseStatus.esriLicenseAvailable )
??????? {
??????????? licenseStatus = (ESRI.ArcGIS.esriSystem.esriLicenseStatus)
??????????????? m_AoInitialize.Initialize(ESRI.ArcGIS.esriSystem.esriLicenseProductCode.esriLicenseProductCodeEngine);
??????????? if (licenseStatus != ESRI.ArcGIS.esriSystem.esriLicenseStatus.esriLicenseCheckedOut )
??????????? {
?????????????? System.Windows.Forms.MessageBox.Show("初始化失敗，應用程序不能運行！");
?????????????? this.Close();
??????????? }
??????? }
??????? else
??????? {
??????????? System.Windows.Forms.MessageBox.Show("ArcGIS Engine產品無效，此程序不能運行！");
??????????? this.Close();
??????? }
??? }
???
??? private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
??? {
??????? // 釋放COM對象并關閉AoInitialize對象
??????? ESRI.ArcGIS.Utility.COMSupport.AOUninitialize.Shutdown();
??????? m_AoInitialize.Shutdown();
?}
}
