根據他的用戶ID獲取用戶的電子郵件地址.net身份

Question

我有以下功能，在過期的鏈接中重新生成確認電子郵件（以完成註冊）。

[AllowAnonymous] 
    [HttpGet] 
    [Route("ResendConfirmationEmail")] 
    public async Task<IHttpActionResult> ResendConfirmationEmail(string userId = "") 
    { 
     if (string.IsNullOrWhiteSpace(userId)) 
     { 
      ModelState.AddModelError("", "User Id is required"); 
      return BadRequest(ModelState); 
     } 
     if (userId.GetHashCode() != null) 
     { 
      var code = await UserManager.GenerateEmailConfirmationTokenAsync(userId); 
      var callbackUrl = new Uri(Url.Link("ConfirmEmailRoute", new { userId, code = code })); 
      string subject = "Please confirm your account"; 
      string body = "Please confirm your account by clicking this : <a href=\"" + callbackUrl + "\">link</a>"; 
      SendEmail(?????, callbackUrl, subject, body); 
     } 
     return Ok(); 
    } 

我怎樣才能從webUsers表中的用戶的電子郵件基於他userid？

Answer 1

您可以從數據庫中使用的UserManager的FindByIdAsync獲取用戶，然後獲得的電子郵件

var user = await UserManager.FindByIdAsync(userId); 
var email = user.Email;
