nlogデータベースターゲットパラメータのレイアウトエラー

Question

nlogデータベースターゲットを使用しようとしています。 データベースを手動で作成しないと、最初は機能しません。 もう一つ重要なことは、私は記録できません。私は私のパラメータのレイアウトについてはエラーが発生します。私は手動でテーブルを作成し、それが動作する「アプリケーション」パラメータのようなレイアウトに定数を置く場合

： はアウトnlog内部ログから置きます。

私はドキュメントに従っていますが、動作させることはできません。私はNLog & NLog.Webの拡張がインストールされています。

ありがとうございます！

エラーメッセージに示されるように、${logged}を定義する必要があります。お使いの設定ファイルに：インストールのクエリを提供する場合

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     internalLogFile="C:\Github\private\WeBees\WeBees Client\WeBees.Server\Logs\nlog.txt" internalLogLevel="Trace"> 

    <variable name="logged" value="my var" /> 
    <targets> 

それとも別のレイアウトレンダラと交換し、例えば${message}、テーブルの作成についてlist of possible layout renderers

を参照してください、NLogは、テーブルを作成します。

LogManager.Configuration.Install(new InstallationContext()); //install all the targets, e.g. database, eventlogger etc. 

：

<target xsi:type="Database" name="db"> 

    <!-- connection string --> 
    <dbProvider>System.Data.SqlClient</dbProvider> 
    <connectionString>server=.\SQLEXPRESS;database=MyLogs;integrated security=sspi</connectionString> 

    <!-- commands to install database --> 
    <install-command> 
    <text>CREATE DATABASE MyLogs</text> 
    <connectionString>server=.\SQLEXPRESS;database=master;integrated security=sspi</connectionString> 
    <ignoreFailures>true</ignoreFailures> 
    </install-command> 

    <install-command> 
    <text> 
     CREATE TABLE LogEntries(
     id int primary key not null identity(1,1), 
     TimeStamp datetime2, 
     Message nvarchar(max), 
     level nvarchar(10), 
     logger nvarchar(128)) 
    </text> 

とC＃、インストールを呼び出します
