これPUTが私のWeb APIのメソッドの呼び出しです-メソッドの3行目（私はASP.NET MVCフロントエンドからWeb APIを呼び出しています）：
client.BaseAddressですhttp://localhost/CallCOPAPI/。
ここにありcontactUriます：
ここにありcontactUri.PathAndQueryます：
そして最後に、これが私の405応答です。
これが私のWeb APIプロジェクトのWebApi.configです。
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "DefaultApiGet",
routeTemplate: "api/{controller}/{action}/{regionId}",
defaults: new { action = "Get" },
constraints: new { httpMethod = new HttpMethodConstraint("GET") });
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
config.Formatters.Remove(config.Formatters.XmlFormatter);私はに渡されるパスダウンストリッピングしようとしたPutAsJsonAsyncのstring.Format("/api/department/{0}", department.Id)とstring.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)運とを。
405エラーが発生するのはなぜですか？

[HttpPut]と、WebAPIコントローラー（ApiController）を使用するということですか？なぜなら、Department（Editメソッド）のフロントエンドコントローラーには[HttpPost]属性があるからです。
@ChrisPrattザ・ValuesController（WebAPIのテンプレートが付属しています1）持っていない

[HttpPut]、などが入れ/ポスト/削除方法の属性...
はい、私はそれがWeb API側でそれらを必要とすることを合理的に確信しています。個人的には、私は常にWeb APIにAttributeRoutingを使用してきたので、私の思い出は少し大ざっぱです。

どうやらそれはWebDAVの問題だったようです。ローカルのIIS（Windowsの機能）をチェックして、インストールされていないことを確認し、インストールされていないことを報告しました...とにかく答えを投稿しました。 .config。

[HttpPut]アクションメソッド定義の前に使用するべきではありませんか？（[HttpPost]および[HttpDelete]適切な場合も同様）
