RegistrationErrorInfo Class


Retrieves extended error information about methods related to multiple COM+ objects. This also includes methods that install, import, and export COM+ applications and components. This class cannot be inherited.

Namespace:   System.EnterpriseServices
Assembly:  System.EnterpriseServices (in System.EnterpriseServices.dll)


public sealed class RegistrationErrorInfo


Gets the error code for the object or file.


Gets the description of the ErrorCode.


Gets the key value for the object that caused the error, if applicable.


Gets a precise specification of the item that caused the error, such as a property name.


Gets the name of the object or file that caused the error.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

The following code example shows how to retrieve extended error information about methods related to multiple COM+ objects.

    string applicationName = "Queued Component";			
    string typeLibraryName = null;
    RegistrationHelper helper = new RegistrationHelper(); 
    // Call the InstallAssembly method passing it the name of the assembly to 
    // install as a COM+ application, the COM+ application name, and 
    // the name of the type library file.
    // Setting the application name and the type library to NULL (nothing in Visual Basic .NET
    // allows you to use the COM+ application name that is given in the assembly and 
    // the default type library name. The application name in the assembly metadata 
    // takes precedence over the application name you provide to InstallAssembly. 
    helper.InstallAssembly(@"C:..\..\QueuedComponent.dll", ref applicationName, ref typeLibraryName, InstallationFlags.CreateTargetApplication);
    Console.WriteLine("Registration succeeded: Type library {0} created.", typeLibraryName);

    // Create a RegistrationConfig object and set its attributes
    // Create a RegistrationHelper object, and call the InstallAssemblyFromConfig
    // method by passing the RegistrationConfiguration object to it as a 
    // reference object
    RegistrationConfig registrationConfiguration = new RegistrationConfig();
    registrationConfiguration.Application = "MyApp";
    registrationConfiguration.InstallationFlags = InstallationFlags.CreateTargetApplication;
    RegistrationHelper helperFromConfig = new RegistrationHelper();
    helperFromConfig.InstallAssemblyFromConfig(ref registrationConfiguration); 


catch(RegistrationException e)

    // Check whether the ErrorInfo property of the RegistrationException object is null. 
    // If there is no extended error information about 
    // methods related to multiple COM+ objects ErrorInfo will be null.
    if(e.ErrorInfo != null)
        // Gets an array of RegistrationErrorInfo objects describing registration errors
        RegistrationErrorInfo[] registrationErrorInfos = e.ErrorInfo;

        // Iterate through the array of RegistrationErrorInfo objects and disply the 
        // ErrorString for each object.

        foreach (RegistrationErrorInfo registrationErrorInfo in registrationErrorInfos)
