Abhishek，

Hi Abhishek,

请查看以下堆栈溢出线程:

Please take a look at the following Stack Overflow thread: How can I store Images in Azure Cosmos DB ?

有两种不同的方法可以实现这一目的.

There are a couple different methods for accomplishing this.

1. 使用指向存储在Azure Blob存储(SQL或Table API)上的物理图像文件的链接将元数据存储在Cosmos DB中.
2. 使用表将元数据和图像文件存储在Cosmos DB中API.

我希望这能回答您的问题.

I hope this answers your question.

以下代码示例用于使用 DocumentClient.CreateAttachmentAsync

The following code example is for storing the image file in Cosmos DB with DocumentClient.CreateAttachmentAsync

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/", 
    fileStream, 
    new MediaOptions 
    { 
       ContentType = "image/jpeg", 
       Slug = "myImage.jpeg" 
    });
}

此致
