Example 2: In this example, we are using the ChildNodesAndTokens property to get all the variable declarations in a given syntax node. We are then iterating through the collection to print out the identifiers of each variable declaration.csharp using Microsoft.CodeAnalysis; using Microsoft.CodeAnalysis.CSharp; using Microsoft.CodeAnalysis.CSharp.Syntax; using System; class Program { static void Main() { string code = @" using System; class Program { static void Main() { int x = 10, y = 20; Console.WriteLine(x + y); } }"; SyntaxTree tree = CSharpSyntaxTree.ParseText(code); var root = tree.GetRoot(); var variableDeclarations = root.DescendantNodesAndSelf().OfType
