適用于 .NET 的 Azure 通訊Email用戶端程式庫 - 1.0.0 版

發行項
04/06/2023

此套件包含適用于 Email Azure 通訊服務的 C# SDK。

開始使用

安裝套件

使用NuGet安裝適用于 .NET 的 Azure 通訊Email用戶端程式庫：

dotnet add package Azure.Communication.Email

必要條件

您需要Azure 訂用帳戶、通訊服務資源，以及具有作用中網域的通訊資源Email。

若要建立這些資源，您可以使用Azure 入口網站、Azure PowerShell或.NET 管理用戶端程式庫。

重要概念

EmailClient 提供傳送電子郵件訊息的功能。

使用陳述式

using Azure.Communication.Email;

驗證用戶端

Email用戶端可以使用從Azure入口網站中的 Azure 通訊資源取得的連接字串進行驗證。

var connectionString = "<connection_string>"; // Find your Communication Services resource in the Azure portal
EmailClient emailClient = new EmailClient(connectionString);

或者，Email用戶端也可以使用有效的權杖認證進行驗證。使用此選項時， AZURE_CLIENT_SECRET 必須設定、 AZURE_CLIENT_ID 和 AZURE_TENANT_ID 環境變數以進行驗證。

string endpoint = "<endpoint_url>";
TokenCredential tokenCredential = new DefaultAzureCredential();
tokenCredential = new DefaultAzureCredential();
EmailClient emailClient = new EmailClient(new Uri(endpoint), tokenCredential);

範例

傳送具有自動輪詢狀態的簡單電子郵件訊息

若要傳送電子郵件訊息，請從呼叫或 SendAsync 函式的 SendEmailClient 簡單多載。

try
{
    var emailSendOperation = emailClient.Send(
        wait: WaitUntil.Completed,
        senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
        recipientAddress: "<recipient email address>"
        subject: "This is the subject",
        htmlContent: "<html><body>This is the html body</body></html>");
    Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");

    /// Get the OperationId so that it can be used for tracking the message for troubleshooting
    string operationId = emailSendOperation.Id;
    Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
    /// OperationID is contained in the exception message and can be used for troubleshooting purposes
    Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}

傳送具有手動輪詢狀態的簡單電子郵件訊息

若要傳送電子郵件訊息，請從呼叫或 SendAsync 函式的 SendEmailClient 簡單多載。

/// Send the email message with WaitUntil.Started
var emailSendOperation = await emailClient.SendAsync(
    wait: WaitUntil.Started,
    senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
    recipientAddress: "<recipient email address>"
    subject: "This is the subject",
    htmlContent: "<html><body>This is the html body</body></html>");

/// Call UpdateStatus on the email send operation to poll for the status
/// manually.
try
{
    while (true)
    {
        await emailSendOperation.UpdateStatusAsync();
        if (emailSendOperation.HasCompleted)
        {
            break;
        }
        await Task.Delay(100);
    }

    if (emailSendOperation.HasValue)
    {
        Console.WriteLine($"Email queued for delivery. Status = {emailSendOperation.Value.Status}");
    }
}
catch (RequestFailedException ex)
{
    Console.WriteLine($"Email send failed with Code = {ex.ErrorCode} and Message = {ex.Message}");
}

/// Get the OperationId so that it can be used for tracking the message for troubleshooting
string operationId = emailSendOperation.Id;
Console.WriteLine($"Email operation id = {operationId}");

傳送含有更多選項的電子郵件訊息

若要傳送電子郵件訊息，請從 EmailClientEmailMessage 接受參數的呼叫或 SendAsync 函式的多 Send 載。

// Create the email content
var emailContent = new EmailContent("This is the subject")
{
    PlainText = "This is the body",
    Html = "<html><body>This is the html body</body></html>"
};

// Create the EmailMessage
var emailMessage = new EmailMessage(
    senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
    recipientAddress: "<recipient email address>"
    content: emailContent);

try
{
    var emailSendOperation = emailClient.Send(
        wait: WaitUntil.Completed,
        message: emailMessage);
    Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");

    /// Get the OperationId so that it can be used for tracking the message for troubleshooting
    string operationId = emailSendOperation.Id;
    Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
    /// OperationID is contained in the exception message and can be used for troubleshooting purposes
    Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}

傳送電子郵件訊息給多個收件者

若要將電子郵件訊息傳送給多個收件者，請將每個配方類型的物件新增 EmailAddress 至 EmailRecipient 物件。

// Create the email content
var emailContent = new EmailContent("This is the subject")
{
    PlainText = "This is the body",
    Html = "<html><body>This is the html body</body></html>"
};

// Create the To list
var toRecipients = new List<EmailAddress>
{
    new EmailAddress(
        address: "<recipient email address>"
        displayName: "<recipient displayname>"
    new EmailAddress(
        address: "<recipient email address>"
        displayName: "<recipient displayname>"
};

// Create the CC list
var ccRecipients = new List<EmailAddress>
{
    new EmailAddress(
        address: "<recipient email address>"
        displayName: "<recipient displayname>"
    new EmailAddress(
        address: "<recipient email address>"
        displayName: "<recipient displayname>"
};

// Create the BCC list
var bccRecipients = new List<EmailAddress>
{
    new EmailAddress(
        address: "<recipient email address>"
        displayName: "<recipient displayname>"
    new EmailAddress(
        address: "<recipient email address>"
        displayName: "<recipient displayname>"
};

var emailRecipients = new EmailRecipients(toRecipients, ccRecipients, bccRecipients);

// Create the EmailMessage
var emailMessage = new EmailMessage(
    senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
    emailRecipients,
    emailContent);

try
{
    EmailSendOperation emailSendOperation = emailClient.Send(WaitUntil.Completed, emailMessage);
    Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");

    /// Get the OperationId so that it can be used for tracking the message for troubleshooting
    string operationId = emailSendOperation.Id;
    Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
    /// OperationID is contained in the exception message and can be used for troubleshooting purposes
    Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}

傳送含有附件的電子郵件

Azure 通訊服務支援使用附件傳送電子郵件。

// Create the EmailMessage
var emailMessage = new EmailMessage(
    senderAddress: "<Send email address>" // The email address of the domain registered with the Communication Services resource
    recipientAddress: "<recipient email address>"
    content: emailContent);

var filePath = "<path to your file>";
var attachmentName = "<name of your attachment>";
var contentType = MediaTypeNames.Text.Plain;

var content = new BinaryData(System.IO.File.ReadAllBytes(filePath));
var emailAttachment = new EmailAttachment(attachmentName, contentType, content);

emailMessage.Attachments.Add(emailAttachment);

try
{
    EmailSendOperation emailSendOperation = emailClient.Send(WaitUntil.Completed, emailMessage);
    Console.WriteLine($"Email Sent. Status = {emailSendOperation.Value.Status}");

    /// Get the OperationId so that it can be used for tracking the message for troubleshooting
    string operationId = emailSendOperation.Id;
    Console.WriteLine($"Email operation id = {operationId}");
}
catch ( RequestFailedException ex )
{
    /// OperationID is contained in the exception message and can be used for troubleshooting purposes
    Console.WriteLine($"Email send operation failed with error code: {ex.ErrorCode}, message: {ex.Message}");
}

疑難排解

RequestFailedException會擲回作為任何不成功要求的服務回應。例外狀況包含從服務傳回之回應碼的相關資訊。
