最简单的WP7记录器

Question

我需要最简单的wp7记录器，没有网络报告或文件存储。只需向控制台报告简单。它应该能够使用字符串，对象和格式化字符串：

• SimpleLogger.WriteLine（ “JustLine”）;
• SimpleLogger.WriteLine（ObjectToBeCastedToString）;
• SimpleLogger.WriteLine（“价格为{0} {1}”，价格，货币）;

Answer 1

public class SimpleLogger
{
    private static DateTime lastLog;

    [Conditional("DEBUG")]
    public static void WriteLine(object value)
    {
        WriteLine((value == null) ? "(null)" : value.ToString());
    }

    [Conditional("DEBUG")]
    public static void WriteLine(string format)
    {
        WriteLine("{0}", format);
    }

    [Conditional("DEBUG")]
    public static void WriteLine(string format, params object[] values)
    {
        var formatted = String.Format(null, format, values);

        Debug.WriteLine("{0:hh:mm:ss.fff} [{1:hh:mm:ss.fff}] {2}", DateTime.UtcNow, DateTime.UtcNow - lastLog, formatted);
        lastLog = DateTime.UtcNow;
    }
}
