The following code example creates a PerformanceCounterCategory with the PerformanceCounterCategory().

It 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)
