How to get IParseTree in ANTLR4?

antlr, antlr4, c#, parse-tree

Solution

Thanks to the comment of Cv4, this is the code I used:

IParseTree tree = SpinParser.expr();

Problem

I am currently using ANTLR4 in C# but I am facing a problem, I don't know how to get the the object/class IParseTree. I find in C# the fully qualified name here is `Antlr4.Runtime.Tree.IParseTree` but how to get the object? ``` AntlrInputStream inputStream = new AntlrInputStream(sSpinTexte); SpinParserLexer SpinLexer = new SpinParserLexer(inputStream); CommonTokenStream commonTokenStream = new CommonTokenStream(SpinLexer); SpinParserParser SpinParser = new SpinParserParser(commonTokenStream); IParseTree tree = ????? ``` Can you please help?
