Azure WCF 服务在 Blob 存储文件上出错

我有一个Windows Azure项目，其中WCF服务作为WebRole。我在 Azure 中有一个存储帐户，我想在其中保存文件。

我的代码在我使用 Azure 模拟器进行测试时工作。

但要知道我遇到了下一个错误：

Could not find a part of the path 'C:'temp'BatchAzure.log'.

我尝试执行的客户端服务：

    string path = @"C:'temp'BatchAzure.log";
    var test = service.SaveGezichtBestand(path, "999999");

我正在使用的方法：

public bool SaveGezichtBestand(string filePath, string memberID)
        {
            bool result = false;
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
            RoleEnvironment.GetConfigurationSettingValue("StorageConnectionString"));
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            // Retrieve a reference to a container 
            CloudBlobContainer container = blobClient.GetContainerReference("facefileblobcontainer");
            // Create the container if it doesn't already exist
            container.CreateIfNotExist();
            //By default, the new container is private, so you must specify your storage account key (as you did above) 
            //to download blobs from this container.
            container.SetPermissions(new BlobContainerPermissions { PublicAccess = BlobContainerPublicAccessType.Blob });
            // Retrieve reference to a blob named "myblob"
            CloudBlob blob = container.GetBlobReference(memberID);
            try
            {
                // Create or overwrite the "myblob" blob with contents from a local file
                using (var fileStream = System.IO.File.OpenRead(filePath))
                {
                    blob.UploadFromStream(fileStream);
                    result = true;
                }
            }
            catch (Exception)
            {
                result = false;
                throw;
            }
            return result;
        }
