示例

下面的代码示例 PerformanceCounterCategory 使用 PerformanceCounterCategory() 构造函数创建一个。The following code example creates a PerformanceCounterCategory with the PerformanceCounterCategory() constructor. 它将提示用户输入 PerformanceCounterCategory 和计算机名称,然后 CategoryName MachineName 从输入的值中设置和属性。It prompts the user for the PerformanceCounterCategory and the computer names, then sets the CategoryName and MachineName properties from the entered values. 然后,它显示 CategoryNameMachineName 和属性的值 CategoryHelp ,如果无法访问,则显示一条错误消息 PerformanceCounterCategoryIt then displays the values of the CategoryName, MachineName, and CategoryHelp properties, or it displays an error message if the PerformanceCounterCategory cannot be accessed.

public static void Main(string[] args)
{
    string categoryName = "";
    string machineName = "";
    PerformanceCounterCategory pcc = new PerformanceCounterCategory();

    // Prompt for fields and set the corresponding properties.
    while (categoryName.Length==0)
    {
        Console.Write("Please enter a non-blank category name: ");
        categoryName = Console.ReadLine().Trim();
        if (categoryName.Length>0)
        {
            pcc.CategoryName = categoryName;
        }
    }
    while (machineName.Length==0)
    {
        Console.Write("Enter a non-blank computer name ['.' for local]: ");
        machineName = Console.ReadLine().Trim();
        if (machineName.Length>0)
        {
            pcc.MachineName = machineName;
        }
    }

    // Display the properties of the PerformanceCounterCategory object.
    try
    {
        Console.WriteLine("  Category:  {0}", pcc.CategoryName);
        Console.WriteLine("  Computer:  {0}", pcc.MachineName);
        Console.WriteLine("  Help text: {0}", pcc.CategoryHelp);
    }
    catch(Exception ex)
    {
        Console.WriteLine("Error getting the properties of the " +
            "PerformanceCounterCategory object:");
        Console.WriteLine(ex.Message);
    }
}
Sub Main(ByVal args() As String)
    Dim categoryName As String = ""
    Dim machineName As String = ""
    Dim pcc As New PerformanceCounterCategory

    ' Prompt for fields and set the corresponding properties.
    While categoryName.Length = 0
        Console.Write("Please enter a non-blank category name: ")
        categoryName = Console.ReadLine().Trim
        If categoryName.Length > 0 Then
            pcc.CategoryName = categoryName
        End If
    End While
    While machineName.Length = 0
        Console.Write( _
            "Enter a non-blank computer name ['.' for local]: ")
        machineName = Console.ReadLine().Trim
        If machineName.Length > 0 Then
            pcc.MachineName = machineName
        End If
    End While

    ' Display the properties of the PerformanceCounterCategory object.
    Try
        Console.WriteLine("  Category:  {0}", pcc.CategoryName)
        Console.WriteLine("  Computer:  {0}", pcc.MachineName)
        Console.WriteLine("  Help text: {0}", pcc.CategoryHelp)
    Catch ex As Exception
        Console.WriteLine("Error getting the properties of the " & _
