ConsoleTraceListener 构造函数

定义

命名空间:

System.Diagnostics

程序集:

System.Diagnostics.TextWriterTraceListener.dll

初始化 ConsoleTraceListener 类的新实例。

重载

ConsoleTraceListener()	初始化 ConsoleTraceListener 类的新实例，并将跟踪输出写入标准输出流中。
ConsoleTraceListener(Boolean)	初始化 ConsoleTraceListener 类的一个新实例，并利用一个选项将跟踪输出写入标准输出流或标准错误流中。

ConsoleTraceListener()

Source:

ConsoleTraceListener.cs

初始化 ConsoleTraceListener 类的新实例，并将跟踪输出写入标准输出流中。

public:
 ConsoleTraceListener();

public ConsoleTraceListener ();

Public Sub New ()

示例

下面的代码示例初始化 ConsoleTraceListener 指定 Console 输出流的 对象，并将其添加到跟踪侦听器集合。 此代码示例是为 ConsoleTraceListener 类提供的一个更大示例的一部分。

// Define a trace listener to direct trace output from this method
// to the console.
ConsoleTraceListener consoleTracer;

// Check the command line arguments to determine which
// console stream should be used for trace output.
if ((CmdArgs.Length>0)&&(CmdArgs[0].ToString().ToLower().Equals("/stderr")))
    // Initialize the console trace listener to write
    // trace output to the standard error stream.
{
    consoleTracer = new ConsoleTraceListener(true);
}
else
{
    // Initialize the console trace listener to write
    // trace output to the standard output stream.
    consoleTracer = new ConsoleTraceListener();
}
// Set the name of the trace listener, which helps identify this
// particular instance within the trace listener collection.
consoleTracer.Name = "mainConsoleTracer";

// Write the initial trace message to the console trace listener.
consoleTracer.WriteLine(DateTime.Now.ToString()+" ["+consoleTracer.Name+"] - Starting output to trace listener.");

// Add the new console trace listener to
// the collection of trace listeners.
Trace.Listeners.Add(consoleTracer);

' Define a trace listener to direct trace output from this method
' to the console.
Dim consoleTracer As ConsoleTraceListener

' Check the command line arguments to determine which
' console stream should be used for trace output.
If (CmdArgs.Length > 0) AndAlso _
   (CmdArgs(0).ToLower.Equals("/stderr")) Then
    ' Initialize the console trace listener to write
    ' trace output to the standard error stream.
    consoleTracer = New ConsoleTraceListener(True)
Else
    ' Initialize the console trace listener to write
    ' trace output to the standard output stream.
    consoleTracer = New ConsoleTraceListener
End If
' Set the name of the trace listener, which helps identify this 
' particular instance within the trace listener collection.
consoleTracer.Name = "mainConsoleTracer"

' Write the initial trace message to the console trace listener.
consoleTracer.WriteLine(DateTime.Now.ToString() & " [" & _
     consoleTracer.Name & "] - Starting output to trace listener.")

' Add the new console trace listener to 
' the collection of trace listeners.
Trace.Listeners.Add(consoleTracer)

注解

此构造函数初始化对象 ConsoleTraceListener 以将 Console.Out 消息写入流。 其 Name 属性初始化为空字符串 (“”) 。

ConsoleTraceListener(Boolean)

Source:

ConsoleTraceListener.cs

初始化 ConsoleTraceListener 类的一个新实例，并利用一个选项将跟踪输出写入标准输出流或标准错误流中。

public:
 ConsoleTraceListener(bool useErrorStream);

public ConsoleTraceListener (bool useErrorStream);

new System.Diagnostics.ConsoleTraceListener : bool -> System.Diagnostics.ConsoleTraceListener

Public Sub New (useErrorStream As Boolean)

参数

useErrorStream

Boolean

若为 true，则将跟踪和调试输出写入标准错误流中；若为 false，则将跟踪和调试输出写入标准输出流中。
