我正在尝试使用PerformanceCounter类通过C#访问位于".NET CLR内存类别"中的性能计数器.但是,无法使用我期望的正确类别/计数器名称来实例化类别

new PerformanceCounter(".NET CLR Memory", "# bytes in all heaps", Process.GetCurrentProcess().ProcessName);

我尝试使用以下代码循环遍历类别和计数器

string[] categories = PerformanceCounterCategory.GetCategories().Select(c => c.CategoryName).OrderBy(s => s).ToArray();
string toInspect = string.Join(",\r\n", categories);

System.Text.StringBuilder interestingToInspect = new System.Text.StringBuilder();
string[] interestingCategories = categories.Where(s => s.StartsWith(".NET") || s.Contains("Memory")).ToArray();
foreach (string interestingCategory in interestingCategories)
{
    PerformanceCounterCategory cat = new PerformanceCounterCategory(interestingCategory);
    foreach (PerformanceCounter counter in cat.GetCounters())
    {
        interestingToInspect.AppendLine(interestingCategory + ":" + counter.CounterName);
    }
}
toInspect = interestingToInspect.ToString();

但找不到任何似乎匹配的东西.是不可能从CLR中观察这些值,或者我做错了什么.

重要的是,环境是在64位Windows 7机器上运行的.NET 4.0.

我已多次看到以下异常情况

    public SomeClass(IEnumerable<T> someValues)
    {
        if (null == someValues)
        {
            throw new ArgumentNullException("someValues");
        }

        int counter = 0;
        foreach (T value in someValues)
        {
            if (null == value)
            {
                string msg = counter + "th value was null";
                // What exception class to use?
                throw new ArgumentException(msg, "someValues");
            }
            counter++;
        }
    }

是否有处理这些案件的指导方针？通常,有任何描述"异常样式"的指南比MSDN文档更详细

• 例外
• ArgumentException的

当使用 MSBuild 针对项目运行各种分析器时，所有失败都将以“静态分析结果交换格式 (SARIF)”格式输出（参见例如https://github.com/sarif-standard/sarif-spec）。例如，构建可能会产生以下结果
