【问题描述】：

我在 C# 和 Android 中使用了名为 aws-cognito-dot-net-desktop-app 的 aws-samples 示例：

aws-cognito-dot-net-desktop-app

它运行良好，并且在 Cognito 中正确注册了用户。

要注册用户，请执行以下操作：

bool success = await helper.SignUpUser(etUserName.Text, etPasswordUser.Text, etEmailUser.Text, etPhoneUser.Text);

通过这种方式创建用户，但需要输入发送到用户电子邮件的代码。代码入口如下：

CognitoHelper cognitoHelper = new CognitoHelper();
return await cognitoHelper.VerifyAccessCode(userName, codeSentToMail);

并且用户注册没有问题，也就是说，它工作正常：

现在我想删除任何创建的用户，我正在为其创建一个任务，如下所示：

internal async Task<bool> DeleteUser(string username)
{
   try
   {
      AmazonCognitoIdentityProviderClient provider =
        new Amazon.CognitoIdentityProvider.AmazonCognitoIdentityProviderClient(new Amazon.Runtime.AnonymousAWSCredentials(), RegionEndpoint.USEast1);            

      DeleteUserPoolRequest request = new DeleteUserPoolRequest();
      request.UserPoolId = username;
      DeleteUserPoolResponse deleteUserPoolClientResponse = await provider.DeleteUserPoolAsync(request);
      return true;
    }
    catch (Exception ex)
    {
       Console.WriteLine(ex);
       return false;
    }
}

执行 DeleteUserPoolRequest 时，会引发异常，指示 Amazon.Runtime.ErrorType.Unknown 类型的错误

知道我做错了什么吗？

欢迎任何cmets或建议。

公共静态异步任务 DeleteUserFromAws(string emailId) { 尝试 { AmazonCognitoIdentityProviderClient 认知 = 新的 AmazonCognitoIdentityProviderClient(awsAccessKeyId, awsSecretAccessKey, Region1); CognitoUserPool cognitoUserPool = new CognitoUserPool(poolId, appClienId, cognito); AdminGetUserRequest adminGetUserRequest = new AdminGetUserRequest(); adminGetUserRequest.Username = emailId; adminGetUserRequest.UserPoolId = poolId; AdminGetUserResponse adminGetUserResponse = 等待 cognito.AdminGetUserAsync(adminGetUserRequest); var getUserNameByEmaliID = adminGetUserResponse.Username;

            AmazonCognitoIdentityProviderClient provider =
              new AmazonCognitoIdentityProviderClient(awsAccessKeyId, awsSecretAccessKey, Region1);
            AdminDeleteUserRequest request = new AdminDeleteUserRequest();

            throw;
        }
    }
