Nlog自定義layoutrenderer

Question

任何人都可以提供一個非常示例自定義layoutrenderer nlog？

我想使縮進，而IM日誌記錄，例如

如果IM調用方法B，方法C

文本日誌文件是這樣的：

Inside Method C 
     Inside Method B 

等。

那就是：

[LayoutRenderer("IndentationLayout")] 
    public sealed class IndentationLayoutRenderer : LayoutRenderer 
    { 
     // Value to substract from stack count 
     private uint _ignore = 12; 

    // Value to pad with. 
    private string _ipadding = "| "; 

    /// <summary>Set the number of (top) stackframes to ignore</summary> 
    public uint Ignore 
    { 
     get { return _ignore; } 
     set { _ignore = value; } 
    } 

    /// <summary>Set the padding value</summary> 
    public string IndentationPadding 
    { 
     get { return _ipadding; } 
     set { _ipadding = value; } 
    } 

    protected override void Append(StringBuilder builder, LogEventInfo ev) 
    { 
     // Get current stack depth, insert padding chars. 
     StackTrace st = new StackTrace(); 
     long indent = st.FrameCount; 
     indent = indent > _ignore ? indent - _ignore : 0; 
     for (int i = 0; i < indent; ++i) 
     { 
      builder.Append(_ipadding); 
     } 
    } 
}

if(NLog.Config.ConfigurationItemFactory.Default.LayoutRenderers.AllRegisteredItems.ContainsKey(
       "IndentationLayout")) 
       return; 

      NLog.Config.ConfigurationItemFactory.Default.LayoutRenderers.RegisterDefinition("IndentationLayout", typeof(IndentationLayoutRenderer));
