member this.UnregisterAllLoggers : unit -> unit

Public Sub UnregisterAllLoggers ()

Examples

The following example creates an Engine object and uses the BuildProjectFile method to build a project file. The FileLogger class is used to log information to a file.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Build.BuildEngine;

namespace BuildAProjectCS
{
    class Program
    {
        static void Main(string[] args)
        {
            // Instantiate a new Engine object
            Engine engine = new Engine();

            // Point to the path that contains the .NET Framework 2.0 CLR and tools
            engine.BinPath = @"c:\windows\microsoft.net\framework\v2.0.xxxxx";

            // Instantiate a new FileLogger to generate build log
            FileLogger logger = new FileLogger();

            // Set the logfile parameter to indicate the log destination
            logger.Parameters = @"logfile=C:\temp\build.log";

            // Register the logger with the engine
            engine.RegisterLogger(logger);

            // Build a project file
            bool success = engine.BuildProjectFile(@"c:\temp\validate.proj");

            //Unregister all loggers to close the log file
            engine.UnregisterAllLoggers();

            if (success)
                Console.WriteLine("Build succeeded.");
            else
                Console.WriteLine(@"Build failed. View C:\temp\build.log for details");
        }
    }
}

Module Module1
    'Add references to Microsoft.Build.Framework and
    'Microsoft.Build.BuildEngine
    Sub Main()
        'Create a new Engine object
        Dim engine As New Engine()

        'Point to the path that contains the .NET Framework 2.0 CLR and tools
        engine.BinPath = "c:\windows\microsoft.net\framework\v2.0.xxxxx"

        'Instantiate a new FileLogger to generate a build log
        Dim logger As New FileLogger()

        'Set logfile parameter to indicate the log destination
        logger.Parameters = "logfile=c:\temp\build.log"

        'Register the logger with the engine
        engine.RegisterLogger(logger)

        'Build the project file
        Dim success As Boolean = engine.BuildProjectFile("c:\temp\validate.proj")

        'Unregister all loggers to close the log file
        engine.UnregisterAllLoggers()

        If success Then
            Console.WriteLine("Build succeeded.")
        Else
            Console.WriteLine("Build failed. View C:\temp\build.log for details.")
        End If
    End Sub

End Module

Remarks

The UnregisterAllLoggers method calls the Shutdown method on every registered logger before unregistering each of them from the Engine.
