这是PUT对我的Web API上的方法的调用-方法的第三行（我从ASP.NET MVC前端调用Web API）：
client.BaseAddress是http://localhost/CallCOPAPI/。
这里是contactUri：
这里是contactUri.PathAndQuery：
最后，这是我的405回复：
这是我的Web API项目中的WebApi.config：
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);我试着剥离下来获取传递到路径PutAsJsonAsync，以string.Format("/api/department/{0}", department.Id)和string.Format("http://localhost/CallCOPAPI/api/department/{0}", department.Id)没有运气。
有谁知道为什么我会收到405错误？

@ChrisPratt要清楚一点，您的意思是放在

[HttpPut]WebAPI控制器（ApiController）上，对吗？因为Department的前端控制器（Edit方法）具有[HttpPost]属性。
@ChrisPratt ValuesController（WebAPI模板随附的那个）

[HttpPut]在Put / Post / Delete方法上没有等等属性。–
是的，我有理由确定它需要Web API方面的支持。就个人而言，我一直只将AttributeRouting用于Web API，所以我的回忆有点粗略。

显然，这是WebDAV的问题。.我检查了本地IIS（Windows功能）以确保未安装它，并说它没有……反正我发布了一个答案，基本上从我的网络中删除了WebDAV模块.config。

[HttpPut]在动作方法定义之前不应该使用吗？（[HttpPost]以及[HttpDelete]适当的地方）
