C# Parser is a package library that allows parsing of C# source code into abstract syntax trees (ASTs) that can be analyzed and manipulated programmatically. It provides a convenient way to retrieve and process information from large C# codebases.

Example 1: Parsing C# code and retrieving method names

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using System;

class Program
{
    static void Main(string[] args)
    {
        // C# code to be parsed
        string code = @"
            class MyClass
            {
                void Method1() { }
                void Method2() { }
            }
        ";

        // Parse code into a syntax tree
        SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);

        // Get the root of the syntax tree
        SyntaxNode root = syntaxTree.GetRoot();

        // Find all method declarations and retrieve their names
        var methodDecls = root.DescendantNodes().OfType();
        foreach (var methodDecl in methodDecls)
        {
            Console.WriteLine(methodDecl.Identifier.ValueText);
        }
    }
}

In this example, we use C# Parser to parse a small C# code snippet and retrieve the names of the methods declared in it. We use the CSharpSyntaxTree class to parse the code into an abstract syntax tree, and then use the DescendantNodes method to find all MethodDeclarationSyntax nodes in the tree. We then retrieve the name of each method declaration using its Identifier property.

Example 2: Renaming variables in C# code

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Syntax;

class Program
{
    static void Main(string[] args)
    {
        // C# code to be parsed
        string code = @"
            class MyClass
            {
                void Method1()
                {
                    int x = 10;
                    int y = 20;
                    int z = x + y;
                }
            }
        ";

        // Parse code into a syntax tree
        SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);

        // Get the root of the syntax tree
        SyntaxNode root = syntaxTree.GetRoot();

        // Find all variable declarations and rename them
        var varDecls = root.DescendantNodes().OfType();
        foreach (var varDecl in varDecls)
        {
            // Get the variable identifier
            var id = varDecl.Variables.First().Identifier;

            // Generate a new identifier
            var newId = SyntaxFactory.Identifier($"{id.ValueText}_new");

            // Replace the old identifier with the new one
            var newVarDecl = varDecl.ReplaceNode(id, newId);

            // Replace the old variable declaration with the new one
            root = root.ReplaceNode(varDecl, newVarDecl);
        }

        // Print the modified code
        Console.WriteLine(root.ToFullString());
    }
}

In this example, we use C# Parser to parse a C# code snippet and rename the variables in it. We first use the CSharpSyntaxTree class to parse the code into an abstract syntax tree, and then use the DescendantNodes method to find all VariableDeclarationSyntax nodes in the tree. We then generate a new identifier for each variable and use the ReplaceNode method to replace the old identifier with the new one. Finally, we print the modified code using the ToFullString method.
