爲<type>的最佳重載的方法匹配具有一些無效參數

Question

我得到一個錯誤，當我打下面的代碼行：

using (_client = new RestClient("url", this)) 

錯誤：最好的重載方法「MyNamespace.RestClient比賽（MyNamespace.MyPresenter，字符串）'有一些無效的參數

我看了上百萬這些「最好的重載方法匹配」的線程，但我的問題似乎是不同的東西。詳細的編譯器輸出說它不能轉換：

MyPresenter [C：\ path \ to \ class \ file]到 MyPresenter [C：\ Windows \ Microsoft.NET \ Framework64 \ v4.0.30319 \ Temporary ASP.NET Files \ root \ 3d988ef4 \ 66e82b30 \ assembly \ dl3 \ 995d0d63 \ 042c184e_aae2cf01 \ ProjectName.DLL]

我不確定這裏發生了什麼問題。類型是相同的。

這裏是我完整的代碼（在ASP.net MVP模式）：

// default.aspx.cs (View class) 
public partial class MyView : Page 
{ 
    private readonly MyPresenter _presenter; 

    public MyView() 
    { 
     _presenter = new MyPresenter(this); 
    } 

    public TextBox OutputText 
    { 
     get { return outputText; } 
    } 

    protected void Page_Load(object sender, EventArgs e) {} 

    protected void GoButton_OnClick(object sender, EventArgs eventArgs) 
    { 
     _presenter.DoStuff(); 
    } 
} 

// default.aspx.designer.cs 
public partial class MyView 
{ 
    protected global::System.Web.UI.WebControls.Button goButton; 
    protected global::System.Web.UI.WebControls.TextBox outputText; 
} 

// MyPresenter.cs 
public class MyPresenter 
{ 
    private RestClient _client; 

    public MyPresenter(MyView view) 
    { 
     View = view; 
    } 

    public MyView View { get; private set; } 

    public void DoStuff() 
    { 
     **using (_client = new RestClient("url", this))** // Error here 
     { 
      _client.DoClientStuff() 
     } 
    } 
} 

// RestClient.cs 
public class RestClient 
{ 
    private readonly MyPresenter _presenter; 
    private readonly string _url; 

    public RestClient(string url, MyPresenter presenter) 
    { 
     _presenter = presenter; 
     _url = url; 
    } 

    public void DoClientStuff() 
    { 
     _presenter.View.OutputText.Text = "Doing client stuff"; 
    } 
}

你有你的參數向後

using (_client = new RestClient("url", this)) 

應該

using (_client = new RestClient(this, "url"))
