将有关调试的信息写入 Listeners 集合中的跟踪侦听器。

重载

Write(String, String)	将类别名称和消息写入 Listeners 集合中的跟踪侦听器。
Write(Object, String)	将类别名称和对象的 ToString() 方法的值写入 Listeners 集合中的跟踪侦听器。
Write(String)	将消息写入 Listeners 集合中的跟踪侦听器。
Write(Object)	将对象 ToString() 方法的值写入 Listeners 集合中的跟踪侦听器。

Write(String, String)

将类别名称和消息写入 Listeners 集合中的跟踪侦听器。

public:
 static void Write(System::String ^ message, System::String ^ category);

[System.Diagnostics.Conditional("DEBUG")]
public static void Write (string message, string category);

[System.Diagnostics.Conditional("DEBUG")]
public static void Write (string? message, string? category);

[<System.Diagnostics.Conditional("DEBUG")>]
static member Write : string * string -> unit

Public Shared Sub Write (message As String, category As String)

参数

message: String

要写入的消息。

category: String

用于组织输出的类别名称。

属性: ConditionalAttribute

示例

以下示例创建一个名为 TraceSwitch 的 generalSwitch。此开关是在代码示例外部设置的。

如果开关设置为 TraceLevelError 或更高，则示例会将第一条错误消息输出到 Listeners。有关将侦听器添加到集合的信息 Listeners ，请参阅 TraceListenerCollection 类。

然后，如果 TraceLevel 设置为 Verbose，则示例在与第一条消息相同的行上输出第二条错误消息。行终止符紧跟第二条消息。

   // Class-level declaration.
   // Create a TraceSwitch.
   static TraceSwitch^ generalSwitch = 
      gcnew TraceSwitch( "General","Entire Application" );

public:
   static void MyErrorMethod( Object^ myObject, String^ category )
   {
      // Write the message if the TraceSwitch level is set to Error or higher.
      if ( generalSwitch->TraceError )
      {
         #if defined(DEBUG)
         Debug::Write( myObject, category );
         #endif
      }
      // Write a second message if the TraceSwitch level is set to Verbose.
      if ( generalSwitch->TraceVerbose )
      {
         #if defined(DEBUG)
         Debug::Write( " Object is not valid for this category." );
         #endif
      }
   }

// Class-level declaration.
// Create a TraceSwitch.
static TraceSwitch generalSwitch = new TraceSwitch("General", "Entire Application");

static public void MyErrorMethod(Object myObject, string category)
{
    // Write the message if the TraceSwitch level is set to Error or higher.
    if (generalSwitch.TraceError)
        Debug.Write(myObject, category);

    // Write a second message if the TraceSwitch level is set to Verbose.
    if (generalSwitch.TraceVerbose)
        Debug.WriteLine(" Object is not valid for this category.");
}

' Class-level declaration.
' Create a TraceSwitch.
Private Shared generalSwitch As New TraceSwitch("General", "Entire Application")


Public Shared Sub MyErrorMethod(myObject As Object, category As String)
    ' Write the message if the TraceSwitch level is set to Error or higher.
    If generalSwitch.TraceError Then
        Debug.Write(myObject, category)
    End If 
    ' Write a second message if the TraceSwitch level is set to Verbose.
    If generalSwitch.TraceVerbose Then
        Debug.WriteLine(" Object is not valid for this category.")
    End If
End Sub

注解

默认情况下，输出将写入实例 DefaultTraceListener。

category使用参数对输出消息进行分组。

此方法调用 Write 跟踪侦听器的方法。
