HTTP DELETE找不到然而

Question

我說這對我的API部門conrtoller當我運行它的網站上說，它沒有找到，我不熟悉C＃與做任何幫助..

[HttpDelete] 
     public async Task<IHttpActionResult> Remove([FromBody] Department tObj, [FromUri]bool? tagAsDeleteOnly) 
     { 
     _bll.Delete(tObj, tagAsDeleteOnly ?? true); 

     var result = await _bll.Save(); 

     return Ok(new WebResult 
     { 
      Data = tObj, 
      Total = (int)result, 
      Result = result > 0 
     }); 
    } 

錯誤說

{ 
    "Message": "No HTTP resource was found that matches the request URI 'http://localhost:8933/api/Department/Remove'.", 
    "MessageDetail": "No action was found on the controller 'Department' that matches the request." 
} 

請求負載

{Key: 18, Users: null, Projects: null, Status: null, Code: "ppp", Name: "lll", IsActive: true,…} 
Code:"ppp" 
IsActive:true 
Key:18 
Name:"lll" 
Projects:null 
State:2 
Status:null 
StatusMessage:null 
Users:null 

這是前端（REACTJS）

delete(form) { 
    debugger 
    form.State = 2; 
    let id = form.Key; 
    this.props.deleter('department/Remove', form);} 

然後繼續這個AJAX

export const deleter = (url, params) => { 
    return(dispatch, getState, api) => { 
      api += 'api/'; 
     return fetch(`${api}${url}`, { 
      method: 'DELETE', 
      headers: { 
       'Content-Type': 'application/json' 
      }, 
      body: JSON.stringify(params) 
     }) 
     .then(response => response.json()) 
     .then(result => dispatch(departmentResult(result, types.DELETER))); 
    } 
} 

林不知道爲什麼它不讀控制器，因爲除了刪除其他控制器的工作..

如下更改方法;

 [HttpDelete("{tagAsDeletedOnly?}")]  
     public async Task<IHttpActionResult> Remove([FromBody] Department tObj, [FromRoute]bool? tagAsDeleteOnly) // use FromRoute 
     { 
      _bll.Delete(tObj, tagAsDeleteOnly ?? true); 

      var result = await _bll.Save(); 

      return Ok(new WebResult 
      { 
       Data = tObj, 
       Total = (int)result, 
       Result = result > 0 
      }); 
     }
