System_CAPS_pubpropertyErrorString

Gets the description of the ErrorCode.

System_CAPS_pubpropertyMajorRef

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

System_CAPS_pubpropertyMinorRef

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

System_CAPS_pubpropertyName

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

NameDescription
System_CAPS_pubmethodEquals(Object)

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

System_CAPS_pubmethodGetHashCode()

System_CAPS_pubmethodToString()

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.

try
{
    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);
    Console.Read();

    // 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.AssemblyFile=@"C:..\..\QueuedComponent.dll";
    registrationConfiguration.Application = "MyApp";
    registrationConfiguration.InstallationFlags = InstallationFlags.CreateTargetApplication;
    RegistrationHelper helperFromConfig = new RegistrationHelper();
    helperFromConfig.InstallAssemblyFromConfig(ref registrationConfiguration); 

}

catch(RegistrationException e)
{
    Console.WriteLine(e.Message); 

    // 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) 
        {
            Console.WriteLine(registrationErrorInfo.ErrorString);
        }
    }
    Console.Read();
}
