Question

我意识到这个问题是通过包含的来观察和解决的 props.setProperty（＆＃34; ner.useSUTime＆＃34;，＆＃34; 0＆＃34;）; 但是，错误仍然存在。我通过nuget添加了corenlp 3.8，我在NetStandard2.0配置中使用c＃visual studio 2017。

我的代码： `

public Dictionary<int, List<Word>> GetPOSFromStandforNLP(string sent)
        {
            var pos = new Dictionary<int, List<Word>>();
            var jarRoot = @"../vendor/stanford-corenlp-3.8.0-models";

            // Annotation pipeline configuration
            var props = new Properties();
            // Annotation pipeline configuration
            var props = new Properties();
            props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
            props.setProperty("ner.useSUTime", "0");

            try
            {
                CultureInfo ci = new CultureInfo("en-US");
                Thread.CurrentThread.CurrentCulture = ci;
                Thread.CurrentThread.CurrentUICulture = ci;

                var curDir = Environment.CurrentDirectory;
                Directory.SetCurrentDirectory(jarRoot);   
                var pipeline = new StanfordCoreNLP(props);
                Directory.SetCurrentDirectory(curDir);
                // Annotation
                var annotation = new Annotation(text);
                pipeline.annotate(annotation);
                // Result - Pretty Print
                using (var stream = new ByteArrayOutputStream())
                {
                    pipeline.prettyPrint(annotation, new PrintWriter(stream));
                    Console.WriteLine(stream.toString());
                    stream.close();
                }

The error:

System.TypeInitializationException: The type initializer for 'edu.stanford.nlp.pipeline.AnnotationPipeline' threw an exception. ---> System.TypeInitializationException: The type initializer for 'edu.stanford.nlp.util.logging.Redwood' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Configuration.ConfigurationManager, Version=0.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

Stanford.NLP.NET是一个IKVM项目。 IKVM是.NET中的now defunkt Java虚拟机实现。它不支持.NET Standard 2.0，只支持.NET Framework和Mono。

所以你的选择是：

目标.NET Framework或Mono
将Stanford.NLP.CoreNLP Java project移植到.NET Standard
将IKVM.NET项目移植到.NET Standard（最好是开源的，以便其他需要快速浏览.NET Standard中的Java代码的人可以这样做）
使用Pinvoke和普通的C-wrapper调用Java作为中间人，使用JNI加载JVM并公开使用JNI调用Java的函数，如described here
使用Java或another language that Stanford.NLP.CoreNLP supports

在c＃中运行Stanford.NLP.CoreNLP 3.8示例时出现TypeInitializationException
