CSharp CodeGenerator is a package library used to automatically generate code at runtime based on a predefined set of instructions.

One example of using the CodeGenerator package is to generate a proxy class for a remote service. The generated code will allow the client application to call methods on the remote service as if it were a local object.

Code example:

using System;
using System.Reflection;
using System.CodeDom;
using Microsoft.CSharp;
using System.CodeDom.Compiler;

public class ProxyGenerator {
    public static object GenerateProxy(Type remoteType) {
        var codeProvider = new CSharpCodeProvider();
        var codeGenerator = codeProvider.CreateGenerator();
        
        var typeDeclaration = new CodeTypeDeclaration(remoteType.Name + "Proxy");
        typeDeclaration.IsClass = true;
        typeDeclaration.IsPublic = true;
        
        foreach(var method in remoteType.GetMethods()) {
            var parameters = method.GetParameters().Select(p => new CodeParameterDeclarationExpression(p.ParameterType, p.Name));
            var methodDeclaration = new CodeMemberMethod();
            
            methodDeclaration.Name = method.Name;
            methodDeclaration.ReturnType = new CodeTypeReference(method.ReturnType);
            methodDeclaration.Parameters.AddRange(parameters.ToArray());
            
            var methodInvoke = new CodeMethodInvokeExpression(new CodeTypeReferenceExpression(remoteType), method.Name);
            methodInvoke.Parameters.AddRange(parameters.Select(p => new CodeVariableReferenceExpression(p.Name)).ToArray());
            
            methodDeclaration.Statements.Add(new CodeMethodReturnStatement(methodInvoke));
            
            typeDeclaration.Members.Add(methodDeclaration);
        }

        var unit = new CodeCompileUnit();
        var ns = new CodeNamespace(remoteType.Namespace);
        ns.Types.Add(typeDeclaration);
        unit.Namespaces.Add(ns);
        
        var parameters = new CompilerParameters(new[] { "mscorlib.dll", "System.dll" });
        parameters.GenerateInMemory = true;

        var result = codeProvider.CompileAssemblyFromDom(parameters, unit);
        var proxyType = result.CompiledAssembly.GetType(remoteType.Namespace + "." + typeDeclaration.Name);
        
        return Activator.CreateInstance(proxyType);
    }
}

This code example demonstrates how to generate a proxy class for a remote type specified by `remoteType` parameter. The generated class has the same name as the original type with a "Proxy" suffix. It includes methods that call methods on the remote type using `System.Reflection` and `System.CodeDom` APIs. The `GenerateProxy` method returns an instance of the generated class. The CodeGenerator package is a part of the .NET Framework Class Library.
