Definisi

Ruang nama:

System.Diagnostics

Rakitan:

System.Diagnostics.TraceSource.dll

Sumber:

TraceSwitch.cs

Mendapatkan nilai yang menunjukkan apakah sakelar memungkinkan pesan penanganan kesalahan.

public:
 property bool TraceError { bool get(); };

public bool TraceError { get; }

member this.TraceError : bool

Public ReadOnly Property TraceError As Boolean

Nilai Properti

Boolean

trueLevel jika properti diatur ke Error, , Warning, Infoatau Verbose; jika tidak, false.

Contoh

Contoh kode berikut membuat baru TraceSwitch dan menggunakan sakelar untuk menentukan apakah akan memancarkan pesan kesalahan. Sakelar dibuat di tingkat kelas. MyMethod menulis pesan kesalahan pertama jika Level properti diatur ke TraceLevel.Error atau lebih tinggi. Namun, MyMethod tidak menulis pesan kesalahan kedua jika Level kurang dari TraceLevel.Verbose.

   // Class-level declaration.
   /* Create a TraceSwitch to use in the entire application.*/
private:
   static TraceSwitch^ mySwitch = gcnew TraceSwitch( "General", "Entire Application" );

public:
   static void MyMethod()
   {
      // Write the message if the TraceSwitch level is set to Error or higher.
      if ( mySwitch->TraceError )
         Console::WriteLine( "My error message." );
      
      // Write the message if the TraceSwitch level is set to Verbose.
      if ( mySwitch->TraceVerbose )
         Console::WriteLine( "My second error message." );
   }

   static void main()
   {
      // Run the method that prints error messages based on the switch level.
      MyMethod();
   }

//Class-level declaration.
/* Create a TraceSwitch to use in the entire application.*/
static TraceSwitch mySwitch = new TraceSwitch("General", "Entire Application");

static public void MyMethod()
{
    // Write the message if the TraceSwitch level is set to Error or higher.
    if (mySwitch.TraceError)
        Console.WriteLine("My error message.");

    // Write the message if the TraceSwitch level is set to Verbose.
    if (mySwitch.TraceVerbose)
        Console.WriteLine("My second error message.");
}

public static void Main(string[] args)
{
    // Run the method that prints error messages based on the switch level.
    MyMethod();
}

' Class-level declaration.
' Create a TraceSwitch to use in the entire application. 
Private Shared mySwitch As New TraceSwitch("General", "Entire Application")    

Public Shared Sub MyMethod()
    ' Write the message if the TraceSwitch level is set to Error or higher.
    If mySwitch.TraceError Then
        Console.WriteLine("My error message.")
    End If 
    ' Write the message if the TraceSwitch level is set to Verbose.
    If mySwitch.TraceVerbose Then
        Console.WriteLine("My second error message.")
    End If
End Sub

Public Shared Sub Main()
    ' Run the method that prints error messages based on the switch level.
    MyMethod()
End Sub

Keterangan

Level Ketika properti diatur ke kepentingan tertinggi, TraceLevel.Error, , Error hanya pesan penanganan kesalahan yang dipancarkan.
