T1.SourceGenerator 1.0.5

We provide following features

• Simple Auto Mapping Clone Object Function
• Simple Auto Mapping any interface to WebApi Client Class
• Dynamic execute SourceGenerator in product Project.

How do I get started ?

First, install T1.SourceGenerator nuget package. Attach AutoMapping Attribute on any class.

using T1.SourceGenerator.Attributes;
namespace MyDemoApp;

[AutoMapping(typeof(Employee))]
public class User
{
    public string Name { get; set; }
    public int Level { get; set; }
    public int Vip { get; set; }
}

public class Employee 
{
    public string Name { get; set; }
    public float Level { get; set; }
    public int Vip { get; }
}

Then in your application code, execute the mappings:

var source = new User();
var dto = source.ToEmployee(); 

If you hope change ToEmployee() method to other extension method, you can do this:

[AutoMapping(typeof(Employee), "CloneToEmployee")]
public class User
{
    public string Name { get; set; }
    public int Level { get; set; }
    public int Vip { get; set; }
}

Then in your application code, execute the mappings:

var source = new User();
var dto = source.CloneToEmployee(); 

How to get Auto Mapping WebApiClient class ?

[WebApiClient(ClientClassName = "SamApiClient", Namespace = "ConsoleDemoApp")]
public interface IMyApiClient
{
   [WebApiClientMethod("mgmt/test1", Method = InvokeMethod.Get, Timeout = "00:00:10")]
   void Test(Request1 req);
    
   [WebApiClientMethod("mgmt/test2", Timeout = "00:00:30")]
   void Test2();

   [WebApiClientMethod("mgmt/test3")]
   Response1 Test3();
   
   [WebApiClientMethod("mgmt/test4")]
   Response1 Test4(int a);
}

Then in your application code, execute the code:

using T1.SourceGenerator;

var client = new SamApiClient(null);

If you prefer a different namespace ("ConsoleDemoApp"), you can custom it.

[WebApiClient(ClientClassName = "SamApiClient", Namespace = "ConsoleDemoApp")]
public interface IMyApiClient
{
    ...
}

If you need constructor injection, you can do it like in the following program example.

[WebApiClient(ClientClassName = "SamApiClient", Namespace = "ConsoleDemoApp")]
[WebApiClientConstructorInject(MyConfig), "myConfig")]
public interface IMyApiClient
{
   ...
}

partial class SamApiClient
{
    partial void Initialize()
    {
        BaseUrl = _myConfig.BaseUrl;
    }
}

Even if you need to specify a variable using a special method for constructor injection, you can do it this way.

[WebApiClient(ClientClassName = "SamApiClient", Namespace = "ConsoleDemoApp")]
[WebApiClientConstructorInject(typeof(IOption<MyConfig>), "myConfig", AssignCode="myConfig.Value")]
public interface IMyApiClient
{
   ...
}

It will produce the following code.

public class SamApiClient
{
    public SamApiClient(IHttpClientFactory httpClientFactory,
        IOption<MyConfig> myConfig)   
    {
        _myConfig = myConfig.Value;
    }
}

run SourceGenerator in product project

Add following code in product project.

using T1.SourceGenerator.Attributes;

namespace ConsoleDemoApp;

[RoslynSourceGenerator]
public class MySourceGenerator : IRoslynSourceGenerator
{
    public void Execute(IRoslynGeneratorExecutionContext context)
    {
        context.AddSource("aaa.g.cs", "namespace ConsoleDemoApp; public enum ProductType { Game, Sport }");
    }
}

then you can use it in product project.

var a = ProductType.Game;
