使用例

ビルド イベントに応答する基本 logger を作成する方法を次の例に示します。

C#

using System.IO;
using System.Security;
using Microsoft.Build.Framework;
using Microsoft.Build.Utilities;

 class,

 Parameters,
    // and a default empty Shutdown() implementation.

 start of the build

            // "parameters" specification in the /logger switch.

            // to pass a log file to this logger. Other loggers may
