属性值

类型：System.String
A String that contains the configuration state to either save or load.

注释

The configuration string contains connection and configuration information specific to the provider. Each provider has configuration settings that are unique to that provider, and these properties are set using the ConfigString property.

The following table lists the available log providers, their description, and their ConfigString information.

Provider	Description	ConfigString property
SQL Server Profiler	Generates SQL traces that may be captured and viewed in SQL Server Profiler. The default file name extension for this provider is .trc.	No configuration is required.
SQL Server	Writes event log entries to the sysssislog table in any SQL Server database.	SQL Server provider requires that the connection to the database be specified, and also the target database name.
Text File	Writes event log entries to ASCII text files in a comma-separated value (CSV) format. The default file name extension for this provider is .log.	The name of a file connection manager.
Windows Event Log	Logs to standard Windows Event Log on the local computer in the Application log.	No configuration is required.
XML File	Writes event log entries to XML formatted file. The default file name extension for this provider is .xml	The name of the XML connection manager.

示例

The following code example loads a package for which logging has been enabled. After loading the package, the LogProviders collection is created, and each log provider in the collection is enumerated over, printing the values for each property, including the ConfigString.

namespace LogProvider_Properties_Test

        {
            // The package is one of the SSIS samples,
            // modified to log information to the "SSIS
            // log provider for Text files".
            string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";
            // Create the Application, and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);

            // Get the LogProviders collection from the package.
            LogProviders logProvs = pkg.LogProviders;
            foreach (LogProvider logProv in logProvs)
            {
                Console.WriteLine("ConfigString:   {0}", logProv.ConfigString);
                Console.WriteLine("CreationName    {0}", logProv.CreationName);
                Console.WriteLine("DelayValidation {0}", logProv.DelayValidation);
                Console.WriteLine("Description     {0}", logProv.Description);
                Console.WriteLine("HostType        {0}", logProv.HostType);
                Console.WriteLine("ID              {0}", logProv.ID);
                Console.WriteLine("InnerObject     {0}", logProv.InnerObject);
                Console.WriteLine("Name            {0}", logProv.Name);
             }
