示例

//This attachment could be any binary you want to attach. Like images, videos, word documents, pdfs etc. it doesn't matter
using (FileStream fileStream = new FileStream(@".\something.pdf", FileMode.Open))
{
    //Create the attachment
    Attachment attachment = await client.CreateAttachmentAsync("dbs/db_rid/colls/coll_rid/docs/doc_rid/attachments/",

返回

表示 Task 异步操作的服务响应的 对象。

实现

示例

以下示例创建一个新文档,然后为该文档创建新的附件

dynamic d = new
{
    id = "DOC1800243243470"
};

Document doc = await client.CreateDocumentAsync(collectionSelfLink, d);

//Create an Attachment which links to binary content stored somewhere else
//Use the MediaLink property of Attachment to set where the binary resides
//MediaLink can also point at another Attachment within Azure Cosmos DB.
Attachment a = await client.CreateAttachmentAsync(doc.SelfLink, new Attachment { Id = "foo", ContentType = "text/plain", MediaLink = "link to your media" });

//Because Attachment is a Dynamic object you can use SetPropertyValue method to any property you like
//Even if that property doesn't exist. Here we are creating two new properties on the Attachment we created above.
a.SetPropertyValue("Foo", "some value");
a.SetPropertyValue("Bar", "some value");

//Now update the Attachment object in the database to persist the new properties on the object
client.ReplaceAttachmentAsync(a);

//Let's now create another Attachment except this time we're going to use a Dynamic object instead
//of a <see cref="Microsoft.Azure.Documents.Attachment"/> as we did above.
var b = await client.CreateAttachmentAsync(doc.SelfLink, new { id = "foo", contentType = "text/plain", media="link to your media", a = 5, b = 6 });

//Now you will have a Document in your database with two attachments.
