c#之无法使用 SendGrid 触发电子邮件以更改 blob 存储

我是 MS 函数的新手，正在尝试创建一个 C# 函数来在 Azure Blob 存储中添加新文件时触发电子邮件。

下面的代码示例:

#r "SendGrid" 
using Microsoft.Extensions.Logging; 
using System; 
using System.Text.RegularExpressions; 
using SendGrid.Helpers.Mail; 
 
 
public static void Run(string myBlob, string filename, ILogger log, out Mail message) 
{ 
    var email = Regex.Match(myBlob, @"^email\:\ (.+)$", RegexOptions.Multiline).Groups[1].Value; 
    log.LogInformation($"Got order from {email}\n License File Name: {filename} "); 
 
    message = new Mail(); 
    var personalization = new Personalization(); 
    personalization.AddTo(new Email(email)); 
    message.AddPersonalization(personalization); 
 
    Attachment attach = new Attachment(); 
    var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(myBlob); 
    attach.Content = System.Convert.ToBase64String(plainTextBytes); 
    attach.Type = "text/plain"; 
    attach.Filename = "license.lic"; 
    attach.Disposition = "attachment"; 
    attach.ContentId = "License File"; 
    message.AddAttachment(attach); 
 
    var msgContent = new Content("text/html", "Your license file attached"); 
    message.AddContent(msgContent); 
    message.Subject = "Thanks for your order"; 
    message.From = new Email("test3@test.com");   
 
} 

我正在运行函数版本 ~2(检查了应用设置变量)。

我的问题是为什么我收到 Mail 参数错误(out Mail message)？

我上次检查时 SendGrid 安装正确。

以下是显示编译错误的日志:(我不知道为什么它无法识别方法中的 Mail 参数)

2018-11-26T05:46:57.013 [Error] run.csx(8,73): error CS0246: The type or namespace name 'Mail' could not be found (are you missing a using directive or an assembly reference?)

请您参考如下方法:

Mail 是 v1 函数中使用的类，它与 v8 SendGrid SDK 一起使用。而对于 v2 功能，SDK 是 v9，我们使用 SendGridMessage，Mail 不再可用，因此出现错误。

如果您确定已安装 Storage 和 SendGrid 扩展，请尝试下面的代码。

#r "SendGrid" 
 
using System.Text.RegularExpressions; 
using SendGrid.Helpers.Mail; 
 
public static void Run(string myBlob, string filename, ILogger log, out SendGridMessage message) 
{   
    var email = Regex.Match(myBlob, @"^email\:\ (.+)$", RegexOptions.Multiline).Groups[1].Value; 
    log.LogInformation($"Got order from {email}\n License File Name: {filename} "); 
 
    message = new SendGridMessage(); 
    message.AddTo(new EmailAddress(email)); 
    var base64Content = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(myBlob)); 
 
    message.AddAttachment( 
        "license.lic", 
        base64Content, 
        "text/plain", 
        "attachment", 
        "License File" 
    ); 
 
    message.AddContent("text/html", "Your license file attached"); 
    message.Subject = "Thanks for your order"; 
    message.From = new EmailAddress("test3@test.com"); 
}
