在找到结果时调用方法

Question

我有以下方法DWCompare，我创建了一个方法ErrorsDiscovered来检查以下方法是否为真。如何避免第二种方法中的错误？

  

错误：无法将方法组“DWCompare”转换为非委托类型bool。

public static void DWCompare()
{
    var performDataHour = DbCall.PerformanceDatas.Where(d => 
        d.loggedAt > hourlyBegin && d.loggedAt < hourlyEnd).ToList();

    var performanceDataOneDay = DbCall.PerformanceDatas.Where(o => 
        o.loggedAt >= dayBegin && o.loggedAt < dayEnd).ToList();

    var UniqueFunctionCallsThisHour = performDataHour.GroupBy(g => g.functionName)
        .ToLookup(g => g.First().functionName, g => g.Average(gx => gx.functionTime))
        .OrderByDescending(g => g.FirstOrDefault()).Take(5);

    var UniqueFunctionCallsDay = performanceDataOneDay.ToLookup(g => g.functionName);

    performEmailDisplay += "<table>";
    performEmailDisplay += "<tr>";
    performEmailDisplay += "<td><b>Function</b></td>";
    performEmailDisplay += "<td><b>Hourly Average</b></td>";
    performEmailDisplay += "<td><b>Daily Average</b></td>";
    performEmailDisplay += "</tr>";

    foreach (var function in UniqueFunctionCallsThisHour)
    {
        var key = function.Key;
        var HourlyAverage = function.First();
        var DailyAverageData = UniqueFunctionCallsDay[key];
        double DailyAverage;

        if (DailyAverageData != null && DailyAverageData.Count() > 0)
        {
            DailyAverage = DailyAverageData.Average(f => f.functionTime);

            if (HourlyAverage > DailyAverage + DailyAverageData.Select(x => 
                x.functionTime).ToList().StandardDeviation())
            {
                performEmailDisplay += "<tr>";
                performEmailDisplay += "<td>" + key + "</td>";
                performEmailDisplay += "<td>" + HourlyAverage + "</td>";
                performEmailDisplay += "<td>" + DailyAverage + "</td>";
                performEmailDisplay += "</tr>";
            }                     
        }
    }

    performEmailDisplay += "</table>";
}

public static void ErrorsDiscovered()
{
    if (DWCompare)
    {
        SendEmail();
    }
}

使用try catch块，以便在出现错误时不调用sendEmail（），将执行catch块     public static void ErrorsDiscovered（）{     尝试     {         DWCompare（）;         发送电子邮件（）;     }     抓住     {         //处理错误     }
