请参考以下代码。CertificateEnrollmentManager可用于从个人信息交换（PFX）消息中导入证书。首先，您需要从uri读取远程文件，将缓冲区解析为base64字符串，然后将证书导入到您的商店。
```
            string pfxCertificate = null;
            string pfxPassword = "";

var remoteUri = "http://XXXXXXXX";
            IRandomAccessStreamReference thumbnail = RandomAccessStreamReference.CreateFromUri(new Uri(remoteUri));
            file = await Windows.Storage.StorageFile.CreateStreamedFileFromUriAsync(".pdf",new Uri(remoteUri), thumbnail);

var buffer = await Windows.Storage.FileIO.ReadBufferAsync(file);
            using (DataReader dataReader = DataReader.FromBuffer(buffer))
            {
                byte[] bytes = new byte[buffer.Length];
                dataReader.ReadBytes(bytes);
                // convert to Base64 for using with ImportPfx
                pfxCertificate = System.Convert.ToBase64String(bytes);
            }

await CertificateEnrollmentManager.UserCertificateEnrollmentManager.ImportPfxDataAsync(
                        pfxCertificate,
                        pfxPassword,
                        ExportOption.NotExportable,
                        KeyProtectionLevel.NoConsent,
                        InstallOptions.None,
                        "Test");
```
